Unable to remove an IFormValidator from a Form
----------------------------------------------
Key: WICKET-709
URL: https://issues.apache.org/jira/browse/WICKET-709
Project: Wicket
Issue Type: Improvement
Components: wicket
Affects Versions: 1.3.0-beta2, 1.2.6
Reporter: Jim Hunziker
Priority: Minor
It seems that there is no way to remove an IFormValidator from a Form. Because
the fields in my Form are inside Panels (only one of which is present at any
given time), the Form fields are not necessarily children of the Form.
When one of the Form's IFormValidators receives a getDependentFormComponents
call, it (correctly, I believe) returns the form components that it validates.
An exception occurs when getParent is called on these components (in attempt to
find the Form somewhere up the hierarchy) up the call stack.
Since the change in the Panel that's present is made via an Ajax update, the
same update would be able to remove the offending IFormValidator when its Panel
is removed. (That is, if there was a method in Form to remove an
IFormValidator.)
For now, I've hacked it so that my IFormValidator checks whether all its Form
Components all have parents before any of its methods return non-null values.
(I'm not just changing the Panel visibility because then the hidden Panels
would still get validated, and I don't want that to happen.)
