Ok, try this
add( new AbstractBehavior() {
@Override
public void renderHead(IHeaderResponse response) {
super.renderHead(response);
response.renderJavascript("<some dynamically
generated JS>", "<uniqueID>");
}
}
);
Every time the component (to that the AbstractBehaivor is added) is redrawn
(eg. Initally or after an AjaxUpodate) the dynamically generated javascript is
renderedinto <HEAD>.
If you want to make sure that it is not rendered twice from another component
with thie AbstractBehavior, just add some "uniqueID" in the renderJavascript
call.

Betreff: Re: Dynamic javascript generation
I need to include this dynamic js in my header with <script> tag like this
in gmail:
<script src="?view=page&name=browser&ver=zpwhtygjntrz
<view-source:https://mail.google.com/mail/?view=page&name=browser&ver=zpwhtygjntrz>"></script>
Some behaviour of that script depends on my session data on server side.
I think that its not very complicated
But I dont want to hardcode it to my html page, because urls and paths my
changes. Dealing with resources provides more reliable configuration etc..
