value set in form control by Javascript to model object
Hi,
I have wicket TextField. The input is read only and its text is changed by a
Javascript component...
So my question is: how can I set the model object to its new value set by
JS?
The problem as you know is that when trying to submit I get an error because
the object is null:
java.lang.IllegalStateException: Attempt to set model object on null model
of component

This sounds like you didn't provide an empty model.
Just use Model.of("")
