Can't Reset Form After DropDownChoice OnChange Handled
I have a drop down choice component, and when the selection changes, I udpate
various form fields by Ajax, in the form as follows:
*public HistoryDropDown(final String id, final Map<K, ?> map, final
Component dateField, final
TrackDetailModel model, final TrackAttribute attribute) {
super(id, map);
final String originalValue = model.getOriginalValue(attribute);
add(new AjaxFormComponentUpdatingBehavior("onchange") {
private static final long serialVersionUID = -1;
@Override
protected void onUpdate(final AjaxRequestTarget target) { // When
selection changes
final String newValue = model.getAttributeValue(attribute); // What the
new choice?
if (newValue.equals(originalValue)) { // If back to original value
dateField.setEnabled(false); // Disable date field
model.restoreOriginalDateAndUser(attribute); // Restore original data
} else { // If changing to new value
dateField.setEnabled(true); // Enable date field
model.setDefaultDateAndUser(attribute); // Effective date = today
} // User = current user
target.addComponent(dateField.getParent()); // Re-render fields
}
});
}
*
The updates work fine (the screen re-renders properly), but if I then click
the form's Reset button, nothing happens. I saw some other posts that said I
have to do a form.modelchanged(), but that didn't any effect.

Do whatever is the best for your logic.
If this is a "create form" then use empty Entity. Whatever 'empty'
means in your domain.
If this is an "edit form" then re-fetch the Entity from the DB by its
id and set it as model object.

All you need is an AjaxButton with .setDefaultFormProcessing(false)
and in its onClick(AjaxRequestTarget target) to do:
getForm().setModelObject(new MyEntity());
target.add(getForm());
i.e. set a new empty model object for the form and all its form
components.

Re: Can't Reset Form After DropDownChoice OnChange Handled
Posted by "Richard W. Adams" <RW...@UP.COM>.
Not sure what you mean, exactly. The only alternative I can see it to keep
an "original" copy of the form model (assuming there IS a single) model,
then add an onclick handler() to the reset button, then go back to the
server, overwrite the current model with the original model, then add the
form component to the AjaxRequestTarget so it's re-rendered. This could be
ugly & error prone real fast, especially if all of the form fields weren't
covered by a single model. \
Am I missing something here?

Yes, you can reset the form quite easily, with or without Ajax. I haven't
read the rest of the thread, but if you just reset the object that the
form
is referencing all the fields would stay in sync and be 'reset'.

Re: Can't Reset Form After DropDownChoice OnChange Handled
Posted by Clint Checketts <ch...@gmail.com>.
Yes, you can reset the form quite easily, with or without Ajax. I haven't
read the rest of the thread, but if you just reset the object that the form
is referencing all the fields would stay in sync and be 'reset'.

Re: Can't Reset Form After DropDownChoice OnChange Handled
Posted by "Richard W. Adams" <RW...@UP.COM>.
I've been doing a lot of Googling on this topic & found this page, which
seems to describe exactly the problem I'm having:
http://www.jaxtut.com/Navigation.jsp
It suggests calling resetFromSession(), though it doesn't give an
implementation & this method doesn't seem to be part of Wicket.
Has anyone found a way to reset the form after the model has changed & the
form re-rendered thru Ajax? If there isn't a way to do this in Wicket, is
there a "Wicket wish list" to add it to?

Re: Can't Reset Form After DropDownChoice OnChange Handled
Posted by "Richard W. Adams" <RW...@UP.COM>.
The form just has a standard HTML reset button:
<input wicket:id="reset-button" type="reset" value="Reset" />
There's no special code associated with the button. Should there be? I
looked at "Wicket in Action," but it doesn't seem to address this issue.
