Deborah, when will this course be available?
deborahk — December 29, 2016 @ 10:26 am
I completed the course last week, but with the end of year holidays, it most likely won’t be published until after the new year. Thanks for asking!
deborahk — January 27, 2017 @ 4:49 pm
This course was published on January 10th, but did not show up in the library until January 12th. Thanks again for asking.

Hi Deborah,
I was wondering if a course about Reactive Forms will be available on PS?
Thanks.

Hi Deborah –
Thanks for explaining in detail, need more about TypeScript.
deborahk — December 29, 2016 @ 10:27 am
What do you need more about TypeScript? I can point you to some TypeScript courses on Pluralsight …

Hi Deborah,
course is great
just finish Dynamically duplicate input elements module and would like to know how can i remove/delete an item from the FormArray.
Thnaks
deborahk — January 27, 2017 @ 4:58 pm
Your could add a deleteAddress() method similar to the addAddress method. In that method, use the techniques presented here to remove the item from the addresses array: http://stackoverflow.com/questions/5767325/how-to-remove-a-particular-element-from-an-array-in-javascript
Does this help?

You can remove the last address added to the array like this:
component.html:
Remove Address
component.ts:
removeAddress(): void{
this.addresses.removeAt(this.addresses.length – 1);
}

Hi Deborah,
I am trying to dynamically create ‘Address’ FromGroup by providing array populated from DB but its not creating required input address group. If my array contains 3 addresses and while creating root FormGroup I also init my FormArray with 3 addresses then it creates and bind the addresses objects otherwise it does not.
What I am trying to do is that my root FormGroup would have blank formArray (e.g. addresses: this.fb.array([])) and it dynamically create FormAddress on the basis of provided array.
Could you please help me on this to how to do this ?
Thanks.

I’m not sure I understand how this is different from the example in my application? Doesn’t it do exactly that?
I don’t get notified of posts to my blog. Could we continue this conversation here: https://app.pluralsight.com/library/courses/angular-2-reactive-forms/discussion
Then we can narrow down what you need that is different from the sample application.
Thanks!

Hey I have tried npm install and it runs correctly but not all the folders and files get installed. For instance in your video “Setting up an Angular 2 Applicaiton” the typings folder is not created. And when I run npm start I get a whol bunch of errors. but the main error is “sh: tsc: command not found”.
deborahk — February 20, 2017 @ 10:18 am
What code are you using? the Start code from my github? Or code from somewhere else? If you are running newer code (like newer files from the Angular seed QuickStart), then you will not get a typings folder anymore.
If you are running my code from github, try npm install again and let me know if it displays any errors.

Saw your Angular 2 Reactive Forms, great video. But when am validating a textbox its showing error in the console “Cannot read property ‘required’ of null”.
Thanks
Gopal — February 7, 2017 @ 2:15 am
Sorry, solved the issue, it was my mistake.
Thanks
deborahk — February 20, 2017 @ 10:18 am
Glad you found it!

Hello Deborah,
Your Angular2 – Reactive Forms is great on Pluralsight. I have a question about the final version.
How would I display the Sign-Up form from a button click in another component (i.e. a modal dialog)?
Thanks
deborahk — February 20, 2017 @ 10:23 am
Thank you for the kind words about the course. Depending how you set up your application, you should be able to use routing.

Deborah,
Hope all is well the reactive forms appears to have vanished from Github.
Regards,
Perry

I see the code here: https://github.com/DeborahK/Angular2-ReactiveForms
