As you know, I have code of my own in this area ;-) L.

Re: ADF Faces javascript rendering
Laurie, We use a Scriptlet API down in : oracle.adfinternal.view.faces.renderkit.core.xhtml.jsLibs ... the basic gist of which is that a Renderer can say hey, I need function foo(), and the Scriptlet API figures out whether that means importing a lib, or writing out an in-place script, and if so, whether it's already been rendered once. Instead of using a Filter to inject into head, we currently blow off the notion that script elements can only be in head. Evil, perhaps, but there's not a browser that really cares, and practical considerations trumped HTML purity. But since the details are hidden inside of the Scriptlets, they could instead just add the scripts to a list that later gets injected by a Filter. Note that this code is currently in adfinternal, which means that it is not a public API, and is not considered legit for code external to ADF Faces to extend. One of my major goals for the ADF Faces codebase is to extract a public API from the current adfinternal rendering APIs, which reminds me I need to post some support for John's api/impl split e-mail... :) -- Adam On 2/21/06, Laurie Harper [EMAIL PROTECTED] wrote: The Tomahawk components 'inject' Javascript file references into the head section of the response by using a filter to buffer and post-process the response.

Re: ADF Faces javascript rendering
Mike, thanks for the link. Yes, I'm familiar with the AddResources stuff in Tomahawk, but was looking for the equivalent functionality in ADF Faces so I can inter-operate with either. L.

I haven't made a full-blown Dojo component yet, but I have used the
af:inputHidden value=#{backingBean.var} id=myId / component of ADF
with Dojo widgets, passing the widget a simple onFoo function along the
lines of 'document.getElementById('myId').value =
MyWidget.getSomeValue();' to sync up the widget with JSF. (note- you
can also submit a display:none CommandButton in this onFoo function, and
do a Partial Page Refresh ... very cool!)
Now, I've just done this hookup with a Facelet--which works fine for
now, can even be packaged into a tag if I want--and not an actual
component, so I can't say what I'd want from a platform perspective to
facilitate this kind of simple Dojo/JS-to-JSF integration. (toDoList[0]
= learn custom components)
Did want to share the pattern, though, as it seems like the kind of
thing MyFaces could facilitate.

I don't see any reason why we can't move that stuff into commons (and actually, I figured it was already in commons), now that we have a commons jar. It's intended as an end-user API. Please open a JIRA issue so we don't forget. You've probably noticed that we're still discussing how commons is going to work :) Maybe it hasn't been done up to this point because the extensions filter isn't included in commons yet. Yeah, that's what I meant; some stuff is in commons already, some stuff is in Tomahawk. Actually, I think most stuff except the filter itself, and maybe the default resource loader impl, are in commons. I added TOMAHAWK-155 to request the filter itself be moved over too. L.
