[Wicket-user] update propertyModel value to null
Hello,
textarea wicket:id=myString rows=10/textarea
FormComponent myStringComp = new TextArea(myString, new
PropertyModel(this, myString));
myStringComp.add(new AjaxFormComponentUpdatingBehavior(onchange){
protected void onUpdate(AjaxRequestTarget target) {
myString
// do stuff
}
});
Using ajax, almost everything seems to work. If I clear the textarea and tab
out, the String myString does not change to null or an empty string, it
retains the previous value.
What am I missing?
Thanks,

Re: [Wicket-user] update propertyModel value to null
onblur has the same outcome as onchange.
Updates to myString that grow it, or shrink it work fine as long as there is
something in the textarea field. Clearing the field retains the previous
value.
BTW, this is using 1.2.4
any other ideas?
On of my coworkers suggested overloading the setMyString method.
To this end, I created:
public void setMyString() {
this.myString = null;
}
this had no affect.

Hi Shawn,
Could you check that you have a single, properly nested form element
in the html? I vaguely remember someone having problems with this.
Erik.

Re: [Wicket-user] update propertyModel value to null
Hello Erik, The form element is there. Hello Igor, I will have check with our software architect before I can upgrade to the 1.3x branch. I am moving on to other functionality for the time being. Thanks to both of you for your assistance. Any other suggestions?

Re: [Wicket-user] update propertyModel value to null
use wicket's ajax debug console to see what the url request is then set a breakpoint in AjaxFormComponentUpdatingBehavior.onEvent and walk it, see why its not setting the value to null -igor On 1/23/07, Shawn Tumey [EMAIL PROTECTED] wrote: Hello Erik, The form element is there.

Re: [Wicket-user] update propertyModel value to null
The input is returning to the server as an empty string .
The field is required, so when the onEvent method checks
protected final void onEvent(final AjaxRequestTarget target)
{
final FormComponent formComponent = getFormComponent();
boolean callOnUpdate = true;
try
{
formComponent.inputChanged();
formComponent.validate();
if (formComponent.hasErrorMessage())
{
formComponent.invalid();
}
else
{
formComponent.valid();
formComponent.updateModel();
}
}
catch (RuntimeException e)
{
callOnUpdate = false;
onError(target, e);
}
if (callOnUpdate)
{
onUpdate(target);
}
}
the component is set as invalid and the model is not updated.
I am not concerned if the component is valid at this stage of the game, I
simply have other models I need to update based on what is (or is not) in
this component.
I understand what it is doing, but I believe it is a mistake to not update
the model. Especially since onUdate is still being called with the old
unupdated values.
