Ajax question
I have a question that I hopefully someone will be able to answer.
I have created a Wicket based framework on top of YUI Context menu in
wicketstuff (menu2). Everything works as expected. It can be used on
Tree/Table for those that are interested.
However, the issue that I have come across is that the menu stops working
when I send back the component that the contextmenu is "listening" on. I
understand that the DOM has changed and the menu needs to be recreated to
reestablish its association. What I don't know is what is the best way to
reestablish the contextmenu. I resend the Javascript to recreate the menu
but that doesn't work. Is there something that I am missing? How do I have
the YUI ContextMenu (in Javascript) re-listen on the recently sent
component?
Thanks in advance,
- Doug
P.S. If you are interested in having a ContextMenu for your Wicket
Application, please check out package
org.wicketstuff.yui.markup.html.menu2.contextMenu. Please be aware that
this is a work in progress but does work. There is also a working example
in the wicketstuff-yui-examples. I hope to have an example for Tree up very
soon.

FYI...there is a working example of this problem in the

Gerolf...thanks for the tip. Very useful tool.
Anyway I figured out a workaround. I placed my tree in a div and had the
menu listen on the div for contextmenu events. Even though I resend the
tree in an Ajax call, the contextmenu still works without resending the menu
creation stuff.

you definitely want to use firefug [0] for that purpose.

My Behavior extends AbstractDefaultAjaxBehavior which implements
IHeaderContributor.
There are no components involved except the one that is to be "listened" in
on for client side clicks.
At this point, I am not sure what I need to do to debug. Is there any JS
debugging tools that I could use in Firefox that anyone would recommend?

You should make your component implement IHeaderContributor. Or your
behavior, depends on how you implement your menu. Then you don't have
to worry about AjaxRequestTarget.

I just found this.
With a AjaxRequestTarget, you can get the HeaderResponse.
Unfortunately, it still doesn't work :-(

Have your component implement IHeaderContributor and override
void renderHead(final IHeaderResponse response);

I am using 1.3 (Trunk).
I am calling AjaxRequestTarget.target.appendJavascript() right after i call
AjaxRequestTarget.target.addComponent(). Is this the right approach?
Do I have access to IHeaderResponse in an Ajax call?
Thanks

Hi, what wicket version are you using and how do you re-invoke the
javascript on ajax update? if you are using wicket 1.3 the best way to
do invoke the javascript is using
IHeaderResponse.renderOnDomReadyJavascript (works on regular page
refresh and also on ajax update).
