Hello people, any more ideas? Again: It's only happening if I immediately submit the form after entering one letter in the AutoCompleteTextField (condition: overridden method getChoices must return at least one entry).
The exception is thrown in AbstractRequestCycleProcessor in line 416 (Wicket 1.3.5). The class tries to retrieve the component by the relative component path and the component is null. Therefore an exception is thrown. I have a second problem (maybe the same cause) with auto complete text fields. If I enter one letter, wait about 0,25 seconds and submit the form, then -the panel containing the auto complete text field will be removed from the view -the new panel is shown via ajax -the div (containing the choices) of the auto complete text field appears without the text field in the new panel. Would appreciate any answers. Thanks in advance, Leigh ________________________________ Von: Phil Grimm <phil.gr...@gmail.com> An: users@wicket.apache.org Gesendet: Montag, den 9.
