You should be able to cast the ones you pass in, but I'm still not
totally sure how you're doing this.
Could you send a code snippet or just commit the code you're working
on in an inactive state (ie not called by anything)?
BTW, in general for the AJAX stuff my thought was to add new widget
elements to the screen definition for new types of UI elements, like
an AJAX combo-box that does server-side lookups as the user is typing
things in. I think we already have another combobox that is pre-
populated when the page is loaded, but I'd rather have these be
different in the screen definition XML so that both could be used and
it would be easy to switch between them.
In other words, I don't know if there is any place where we would
override the default functionality, I'd rather add these as new
features with new XML elements (or attributes to extend existing ones)
and make them otherwise independent of the existing stuff.

I'm working on modifying the screen widgets to support Dojo (or any
other third party library). I set up the widgets to get their
rendering classes from a factory method instead of using the new
operator. The factory method uses the ObjectType.getInstance(...)
methods to create the class instances.
Everything works great except for one thing. Some of the rendering
classes have constructors that take
javax.servlet.http.HttpServletRequest
javax.servlet.http.HttpServletResponse
arguments. When I use the request and response objects found in the
screen widget context as arguments for the
ObjectType.getInstance(...) method, an exception is thrown - because
the objects don't implement the correct interfaces:
java.lang.NoSuchMethodException:
org
.ofbiz
.widget
.html
.HtmlFormRenderer
.<init>(org.apache.catalina.connector.RequestFacade,
org.apache.catalina.connector.ResponseFacade).
Those classes implement the javax.servlet.ServletRequest and
javax.servlet.ServletResponse interfaces - which are the super
interfaces of the ones needed for the constructor.
I'm stuck. I don't know where to go from here.
Any ideas?
