problems with form submits and AJAX modal window

[Alexander Elsholz <al...@widas.de>]

hi,

i've problems with submitting my form in a modal window. when i use the same
component (surrounded with a panel) directly on a page everything works fine. 

the problem is, that all component-models are set to null.

in the request-map i found these parameters:
-random:0.5499189677089167
-button:"1"
-forme_hf_0:""


here are the ajax-debug messages:
  INFO:
INFO: Initiating Ajax POST request on
?wicket:interface=:6:pnlPanel:modal.test:content:content:form:btn.test.test:1:
IActivePageBehaviorListener:0:-1&wicket:ignoreIfNotActive=true&random=
0.20329140486022013
INFO: Invoking pre-call handler(s)...

and a bit stacktrace:

Can't convert null value to a primitive class: int for setting it on

i also have an onchange-behavior on a dropdownchoice, where i en- and disable
other fields. that works fine in both cases, page and modal window.

thanks alex
