Re: RadioChoice and Ajax to display a panel of dropdowns
The books you mentioned are the places to look at. If i google "wicket component not visible" the third entry brings up the solution. And in the list this question was answered quite often. But it surely depends on search phrase. But now it's answered again. At least here you will get almost ever an answer. Cheers Per 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.

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?

If you add a visible and an invisible panel you have to override this on

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.
