[Wicket-user] Problem with javascript initialization order and header contributions
Hi, I have some javascript with initialization code that needs functions from wicket-ajax.js. However, my javascript is loaded (and run) before wicket-ajax.js. The javascript is added in a component as follows: add(HeaderContributor.forJavaScript(this.getClass(), AutoLogout.js)); Is there a way to force header contributions to load in a certain order? Or, is there a way to run the initialization when all javascript has been loaded? The (old) thread http://www.nabble.com/header-contribution-ordering-tf1768566.html did not provide an answer.

Oh, and euh, I am using a Wicket pre-1.2.5 snapshot from 2007-01-23. Erik van Oosten wrote: Hi, I have some javascript with initialization code that needs functions from wicket-ajax.js.

Sort of. HeaderContributors are designed so that if you add them twice,
they only render once (so you can have multiple components on the page
share the same contributor).
Unfortunately, wicket-ajax.js is rendered as a kind-of composite
HeaderContributor, so you can't just go like this:
add(HeaderContributor.forJavaScript(AbstractDefaultAjaxBehavior.JAVASCRIPT);
...as you'll get two of them. :-(
This may well work, actually, but it's not very nice.
We should probably get AbstractDefaultAjaxBehaviour to add its stuff as
proper HeaderContributors so that this works.
Would you like to open a JIRA issue for this? I expect it affects both
1.3 and 2.0, and won't be fixed for the 1.2.x branch. :-)
Or, is there a way to run the initialization when all javascript has
been loaded?
You can use the window.onload event and hook into that. If you're using
prototype, something like:
Event.observe(window, onload, function() {
doStuff();
});
I doubt it'll fix your problem though.

Al

You can use the window.onload event and hook into that. If you're using prototype, something like I am not using prototype. I 'fixed' it with by hacking the onload attribute on one of my templates.
