Re: Label update after change of radiochoice by ajax not working
I've added a jira-issue (https://issues.apache.org/jira/browse/WICKET-2806) for this. Cheers Per - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Label update after change of radiochoice by ajax not working
Hi *,
i have a courious situation here. My TestHomePanel is running green, but in
browser the label is not updated. If i remove the css-class from the choices it
works as expected. It seems that the lookup of the radios in the group is not
working. But i don't find the place in code to check.
Is someone seeing the cause or knows where the radios in the group will be
handled?
Cheers

Re: RadioChoice and Ajax to display a panel of dropdowns
Hey Jeff,
did you override this?
/**
* Override this method if you want onBeforeRender to be called even
when your component is not
* visible. default this returns false.
*
* @return boolean, if true then onBeforeRender is called even for
none visible components,
* default false.
*
* @see Component#onBeforeRender()
*/
protected boolean callOnBeforeRenderIfNotVisible()
{
return false;
}
If you add a visible and an invisible panel you have to override this on
the invisible one.

Per
I want to create a list of radio buttons [I have that working] and an
ajax event to fire whenever a radio button is clicked [I have this
working]. If the radio button matches the one I am interested in then I
want to display additional information that must be filled in. A radio
button selection is required.
I cannot get the additional information to display when I add the
component back to the target. I think it is because the additional
information is originally set to not visible so the output markup id is
not written out. How would I go about doing this? It seems pretty
standard. Do I need to use panels and swap the appropriate panel [1 -
empty panel, 2 - panel with additional info] into the target when
needed? That seems like a lot of code to do something fairly simple.
My code is below.
Thanks.

Only a shot in the dark, but is
typeBox.setOutputMarkupPlaceholderTag(true) helping? You could use it
instead of
setOutputMarkupId(true), because its done there to. Otherwise i would
have to create a testcase for this situation.
There are different places to get informations:
- search this list
- read the wiki
- check the examples
- read a wicket book (many good out there)
It's all explained on the website. Or do you expect them elsewhere?

RE: RadioChoice and Ajax to display a panel of dropdowns
Adding the call to that method seemed to solve the problem.
The places you mentioned are the usual places to look for information.
However I searched the list, read the wiki, checked the examples, and
looked through some books. I also tried to google what I was trying to
do.
It just seemed like this was a pretty common thing to do and I would
have thought an answer would have been found much quicker.
Do you recommend any books in particular. I have Wicket in Action and
have ordered Pro Wicket. Are there other books that I should be
looking at?
Thanks.
