More than one Facelets portlet causes an exception

["Papaioannou, Todd" <tp...@ncr.com>]

I have two portlets that both work when they are loaded into my portal
on their own. I can hammer them to my heart's content as long as only
one is loaded. When I load the second one and try to click on any link,
or do any type of action, the follow exception gets thrown:

Caused by: java.lang.ClassCastException:
com.sun.facelets.el.LegacyELContext
	at com.sun.facelets.el.ELAdaptor.getELContext(ELAdaptor.java:48)
	at
com.sun.facelets.impl.DefaultFaceletContext.<init>(DefaultFaceletContext
.java:82)

ricPortlet.java:396)

It's unclear to me why there would be a class cast exception since I
have checked that every jar dotted around the place is the same version.

I even tried to take all the jars that would have been in WEB-INF/lib
and stick them into tomcat/common/lib/ext but then I get the following
error:

Caused by: java.lang.IllegalAccessError: tried to access field
com.sun.facelets.FaceletViewHandler$NullWriter.Instance from class
com.sun.facelets.FaceletPortletViewHandler.

I guess this precludes the facelet.jar file being loaded by a different
class loader.

I am using facelets 1.1.0a1 and myfaces 1.1.1.

Any ideas what's causing this, or any suggestions on how to resolve it?
Needless to say, this is quite a show stopper!

Thanks
