Description

DynamicTextAreaModel with 'minLength': 0 in "validators" still requires at least one character gets entered, please look into the stackblitz.

const myTextArea = new DynamicTextAreaModel({ id: "myTextArea", label: "My Textarea", validators: { "required": null, "minLength": 0 } });

It behaves like when you have the 'minLength': 1 for the DynamicTextAreaModel validators property.
To fix I totally dropped validators, but would be good if we could keep it and set it to 0 the min length validation was not necessary.

Please advise.

Hello @fbayanati ,

when you have minlength at 0 why even use the validator in the first place?

Seems like a similiar issue to this angular issue here: angular/angular#23749

I think its a problem with the angular validator itself instead of dynamic forms

Thank you for helping out here! I also could not evaluate a legitimate bug here.
