What happened?

Hi Team,

We are getting "Cannot read properties of null (reading 'length')" issue on form control fields like "ix-textarea" or "ix-input" having two way binding in angular with null value.

In this case the control does not appear on form/screen, attached the snippet.

Can we handle null check at ix framework side so that at least form control should be seen on the screen.

we are using below version:

"@siemens/ix": "2.7.0",

"@siemens/ix-angular": "2.7.0",

"@siemens/ix-icons": "2.2.0",

What type of frontend framework are you seeing the problem on?

Angular

Which version of iX do you use?

2.7.0

Code to produce this issue.

<ix-textarea
          id="text-area-for-{{ fieldName }}"       
          [(ngModel)]=null?
</ix-textarea>
