if g_form.isNewRecord set assignment group

[DIVI1]

I need to declare value of assignment group in 'Problem' Table. 

And here is a problem, cause I just want to declare assignment group only for new records, while updating change of the assignment group should be possible.

That's how my client script look like :

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   if (isLoading || newValue === '') {
      return;
   }
 if(g_form.isNewRecord()){
   g_form.setValue('assignment_group', '6ae3f5b21b479850bf327bb5464bcb45');
}
}

After when I'm trying to create a Problem I've got message below assignment group field:

Hi @DIVI1 

Then you should use the default value instead of a BR.

One less logic to evaluate after insert, and you will see the value before the record is saved the first time.

[DIVI1]

Actually it doesn't work like that, cause If I'll declare default value, The user is still able to change it before save ticket

[Peter Bodelier]

If it's not supposed to change, why not set the field read only?

A default value always only is for new records 

[DIVI1]

I mean it should be possible to change in the future, while updating the ticket for example, but not while creating.

In that case, you would need a onLoad Client script, or UI Policy script:

if(g_form.isNewRecord() ){

g_form.setReadOnly("assignment_group",'true');

}
