Let your component implement IHeaderContributor and add the line of
javascript in the renderHeader method

Hello everyone,
I have a small problem. I have a wicket component and the idea is that the
programmer can add numerous messages to it and whenever the component is
rendered (is added to a requesttarget probably) some javascript is
executed to iterate over the messages and displays them.
I thought that I could simply override onBeforeRender(), or
onAfterRender(), but I simply can't figure out how to append javascript.
Basically I just want to have a line of javascript executed, like
messagebox.displayMessage('asdasdasd').
Before someone asks why I just don't add a label with the message, the
messagebox is dragable, fades after a while and should display messages
for a set amount of time (before the next message is displayed) and should
also be used on client side without requests.
Any thoughts? Help would be appreciated.
The last resort would be to give the requesttarget to the component and
append javascript directly, but that seems more complicated then
necessary.
