Updates on model of FormComponents not being displayed after Ajax call

2011-08-31 Thread Jonas Pohlandt 
Hello everyone,

in an AjaxFormComponentUpdatingBehavior callback I make some changes to the 
object which is the target of the CompundPropertyModel of a form. After the 
changes are made, I add the FormComponents (RequiredTextFields) that are mapped 
to the changed properties of the model object to the AjaxRequestTarget. If I 
log the property values to the console, I can see that have the expected 
(changed) values. Unfortunately, the FormComponents do not show the updates 
after the Ajax call returns. Interestingly, the form validation uses the 
expected/changed values after the click on a submit button, even though the 
FormComponents still show the wrong (unchanged) values.

Is there something besides the adding of the respective components to the 
AjaxRequestTarget that I am missing here?

Any help highly appreciated,
Jonas

Hi Jonas, you need to notify those form components about their model value
change.
e.g.
formComponent.modelChanged();
target.add(formComponent);

AW: Updates on model of FormComponents not being displayed after Ajax call

Hi Pedro,

just tried that. Unfortunately it did not work. 
I checked the source: 
public final void modelChanged()
{
// Call user code
internalOnModelChanged();
onModelChanged();
}

Both internalOnModelChanged and onModelChanged are empty in their default 
implementation by Component (which is not overwritten by RequiredTextField or 
any of its superclasses).

FormComponent overrides internalOnModelChanged. I guess the problem is the
raw input cache in the form component. Since you changed the model value,
you also needs to make sure that this user input cache will be discarded.
Try FormComponent#clearInput before add it in the target.
