ERROR Error: Cannot find control with name: '[object Object]

I'm working with Reactive Forms and I'm trying to pass my form down to child components, but I'm running into the error above. Initially at the top level of the form I was using a FormArray to hold my form and that was working fine before I tried passing it down to the child components. Thanks to this post I now know that the top level of a form should be a FormGroup and the FormArray should be a child of the FormGroup.
So now I am nesting my FormArray inside of a FormGroup and I'm getting the error above. I'm not sure what I'm doing wrong? Below in the relevant code.
// Parent component.ts
ngOnInit() {
if (!!this.rows) {
this.tableForm = new FormArray([]);
this.rows.forEach((row) => {
this.rowGroup = new FormGroup({})
this.columns.forEach(column => {
this.rowGroup.addControl(column.key, new FormControl(row[column.key]));
});
this.tableForm.push(this.rowGroup);
})
this.tableGroup = new FormGroup({
rows: new FormControl(this.tableForm)
})
}
}

Showing changes without refreshing in VueJS

I'm so new in VueJS and still don't control much of its funcionalities,
I'm trying when I update or delete something in my window not need to refresh to see the changes...how can I do it, please?
My functions work perfectly in my controller, just need to solve the question of seeing changes.
Here I post my code if it helps...thank you very much!!
UpdateProfile.vue:
<div class="field">
<label class="label">Schedules</label>
<!--Edit and Delete Schedules-->
<div v-for="schedule in sortedDays(data.schedulesDisplayed)" class="control">
<div class="container">
<div class="field">
<label class="label">Week Day: {{schedule.week_day}}</label>
</div>
<div class="row">
<div class="col">
<div class="row">
Opening Time: <input class="input" type="text" placeholder="Pub schedules" v-model="schedule.opening_time">
</div>
</div>
<div class="col">
<div class="row">
Closing Time: <input class="input" type="text" placeholder="Pub schedules" v-model="schedule.closing_time">
</div>
</div>
</div>
<div class="field">
<div class="buttons is-left">
<div class="button is-info" #click="updatePubSchedule(schedule)">
<span class="icon"><i class="fas fa-save fa-lg"></i></span>
<span>Save</span>
</div>
<div class="button is-danger" #click="deletePubSchedule(schedule)">
<span class="icon"><i class="far fa-trash-alt"></i></span>
<span>Delete Schedule</span>
</div>
</div>
</div>
</div>
</div>
</div>
updatePubSchedule(schedule){
var instance = this;
this.api.put('/pubschedules/update/' + this.data.id, schedule).then(response => {
console.log(schedule);
//data = response.data;
instance = response.data;
});
},
deletePubSchedule(schedule){
var instance = this;
this.api.delete('/pubschedules/delete/' + this.data.id, schedule).then(response => {
//data = response.data;
instance = response.data;
});
},
And in my controller:
/**
* #param Pub $pub
*/
public function updatePubSchedule(Pub $pub)
{
//json_die(request()->all());
Schedule::where([
['pub_id','=', $pub->id],
['week_day' ,'=', request()->get('week_day')]
])->update(request()->all());
}
/**
* #param Pub $pub
*/
public function deletePubSchedule(Pub $pub)
{
Schedule::where([
['pub_id','=', $pub->id],
['week_day' ,'=', request()->get('week_day')]
])->delete();
}

I don't know how you get your initial data but you can have a GET request that gets fresh data from the laravel after you update/delete initial data.
With the response from that request you can update your data.schedulesDisplayed prop.
Important! You need to set the :key attribute in the div that uses v-for rendering like this
<div v-for="(schedule, index) in sortedDays(data.schedulesDisplayed)" :key="index" class="control">
I used the index for the sake of this example but you should use a unique property of sortedDays return.

Meteor template not updating on changed data

I'm currently building a nifty little 'talent point distributor' view, similar to what popular RPG games offer. I didn't want a huge wall of HTML code for all the buttons and textboxes, so I created a template to which I pass two parameters:
the name of the stat I want to alter
the initial value of the stat
The template renders correctly, and I notice that when I log the results to the console, the variable seems to be changed correctly. However, the displayed value does not change and will always stay at 0.
Here is the template itself:
<template name="attributeStepper">
<div class="row" style="margin: 1em;">
<div class="col-sm-3 col-md-2">
<h4>{{toUpper attribute}}</h4>
</div>
<div class="col-sm-6 col-md-4">
<div class="btn-group" role="group">
<button type="button" class="btn btn-default btn-value-dec">
<span class="glyphicon glyphicon-chevron-down"></span>
</button>
<button type="button" class="btn btn-default disabled">{{attributeValue}}</button>
<button type="button" class="btn btn-default btn-value-inc">
<span class="glyphicon glyphicon-chevron-up"></span>
</button>
</div>
</div>
</div>
</template>
Here is the helper I defined for the template:
Template.attributeStepper.helpers({
toUpper : function(str) {
return str.substring(0, 1).toUpperCase() + str.substring(1);
}
})
Template.attributeStepper.events({
'click .btn-value-inc' : function(event, tmpl) {
tmpl.data.attributeValue ++;
},
'click .btn-value-dec' : function(event, tmpl) {
tmpl.data.attributeValue --;
}
});
And this is how I call the templates from the actual view:
<div class="panel panel-default">
<div class="panel-heading">
<h3 class="panel-title">Attributes</h3>
</div>
{{ >attributeStepper attribute="strength" attributeValue="0"}}
{{ >attributeStepper attribute="courage" attributeValue="0"}}
{{ >attributeStepper attribute="intelligence" attributeValue="0"}}
{{ >attributeStepper attribute="agility" attributeValue="0"}}
{{ >attributeStepper attribute="dexterity" attributeValue="0"}}
{{ >attributeStepper attribute="intuition" attributeValue="0"}}
{{ >attributeStepper attribute="charisma" attributeValue="0"}}
</div>
I hope you can make any sense out of this and tell me what I'm doing wrong, because I feel like I'm not following the mindset behind Meteor correctly yet.
Cheers!

There is nothing wrong but also nothing reactive in your code. For the attributeValue you should use a template based ReactiveVar which is created at the onCreate Event
Template.attributeStepper.onCreated(function() {
if (! _.isUndefined(this.data.startingValue))
this.attributeValue = new ReactiveVar(Number(this.data.startingValue));
else
this.attributeValue = new ReactiveVar(0);
})
You can use some initialValue from Template as you like
See complete example at the MeteorPad I created for you.
http://meteorpad.com/pad/Zw7YnnW57uuGKcu3Q/MultipleTemplateUsage
This should solve your question
Cheers

Do you have idea about reactive-var in meteor (Meteor Doc) or you can also use Session instead of reactive-var (ReactiveVar is similar to a Session variable)
Have a look at changes as per your code.
Here is the template(.html)
<template name="attributeStepper">
<div class="row" style="margin: 1em;">
<div class="col-sm-3 col-md-2">
<h4>{{toUpper attribute}}</h4>
</div>
<div class="col-sm-6 col-md-4">
<div class="btn-group" role="group">
<button type="button" class="btn btn-default btn-value-dec">
<span class="glyphicon glyphicon-chevron-down"></span>
</button>
<button type="button" class="btn btn-default disabled">{{getAttributeValue}}</button>
<button type="button" class="btn btn-default btn-value-inc">
<span class="glyphicon glyphicon-chevron-up"></span>
</button>
</div>
</div>
</div>
</template>
Here is helpers for your template(.js)
Template.attributeStepper.created = function(){
this.attributeValue = new ReactiveVar(parseInt(this.data.attributeValue));
}
Template.attributeStepper.helpers({
toUpper : function(str) {
return str.substring(0, 1).toUpperCase() + str.substring(1);
},
getAttributeValue : function(){
return Template.instance().attributeValue.get();
}
});
Template.attributeStepper.events({
'click .btn-value-inc' : function(event, tmpl) {
tmpl.attributeValue.set(tmpl.attributeValue.get()+1)
},
'click .btn-value-dec' : function(event, tmpl) {
tmpl.attributeValue.set(tmpl.attributeValue.get()-1)
}
});
Template.attributeStepper.created = function(){...} method called before your template's logic is evaluated for the first time.

show element in template if owner meteor js

I am writing a messaging app which has a delete / edit function for a user for a given message that is submitted. What I would like to do is write something like:
{{#if currentUser._id === this._id}}
<!-- Show -->
{{/if}}
But this is probably wrong I have a template written for the message record:
<template name="message">
<div class="row message-row">
<div class="col-md-12">
<div class="message-container">
<div class="message-avatar">
<img src="{{userAvatar}}">
</div>
<p>{{message}}</p>
<div class="message-time">{{prettifyDate time}}</div>
<!-- this is the div to hide / show based on the conditional -->
<div class="message-controls">
<button class="btn btn-link btn-xs" type="button" id="deleteMessage"><i class="fa fa-trash-o"></i></button>
<button class="btn btn-link btn-xs" type="button" id="editMessage"><i class="fa fa-edit"></i></button>
</div>
<!-- end -->
</div>
</div>
</div>
</template>
And I am using the following in my client.js
Template.messages.messages = function() {
return Messages.find({}, { sort: {time: -1} });
}
But at this point I am stuck

Assuming your message documents have a userId field, you can simply do this:
Template.message.helpers({
isOwner: function() {
return this.userId === Meteor.userId();
}
});
and:
{{#if isOwner}}
<!-- controls -->
{{/if}}
You could also make a more flexible, reusable global helper for this:
Template.registerHelper('isCurrentUser', function(userId) {
return userId === Meteor.userId();
});
<!-- in this example, the document might have an `ownerId` field rather than `userId` -->
{{#if isCurrentUser ownerId}}{{/if}}
Of course, you also need to validate the updates on the server with the allow/deny API or with custom methods.

how to generate list dynamically in angular.js

can you please tell me how to create list dynamically in angulat.js..Actullly I am able to make list when user press add button and fill the field .
In other words ,Please check this fiddle whenever you fill the fields it generate a row.And you can get Id when you click the row .Fiddle http://jsfiddle.net/wc4Jm/6/
Now I am trying to do this using bootstrap model .in other words on button click first I show a pop up screen then there is "add" button .on click that it generate the row.but I am getting "undefined".My I insert the model div inside the controller ? here is
http://jsbin.com/vubojoxo/4/
Why I am getting this error ?
XMLHttpRequest cannot load file:///C:/Users/asd/Desktop/angular/angularproject/dialog.html. Received an invalid response. Origin 'null' is therefore not allowed access.
I am getting this error when I used plunker..and run in my desktop ..
I make this html ?

js code:
var myApp = angular.module('plunker', ['ui.bootstrap']);
myApp.controller('DialogDemoCtrl', function($scope,$dialog) {
$scope.items = [];
$scope.activeItem = {
id:'',
name: '',
content: ''
};
$scope.addItem = function () {
$scope.activeItem.id = $scope.items.length + 1;
$scope.items.push($scope.activeItem);
$scope.activeItem = {}; /* reset active item*/
};
$scope.getId = function (item) {
alert('ID: '+item.id);
};
$scope.openPopupScreen = function () {
alert('Check Open pop up screen');
$dialog.dialog({}).open('dialog.html');
};
});

Check this Plunker
In this example i used angular-ui library which wraps bootstrap's modal to angular
based on this StackOverflow Answer
ModalDemoCtrl
$scope.items = [];
$scope.getId = function(item) {
alert('ID: ' + item.id);
};
// This opens a Bootstrap modal
$scope.open = function() {
var modalInstance = $modal.open({
template: $scope.modal_html_template,
controller: ModalInstanceCtrl
});
modalInstance.result.then(function(newItem) {
// On modal success
newItem.id = $scope.items.length + 1;
$scope.items.push(newItem);
}, function() {
// On modal cancelation
});
}
ModalInstanceCtrl
$scope.name = '';
$scope.content = '';
$scope.ok = function() {
var response = {
