[jboss-user] [JBoss Portal] - Re: Is the header a portlet?

[rutfield]

Glad to. It is basically the portletswap iframe for 2.4 with different URL and height/width. I thought I'd try this one first.
This is a trimmed down version that exhbits the issues.
I do not have a jboss-portlet.xml (unlike the samples in the reference guide). If I add a   to my iframe-object.xml, I get an error.

The portal's Admin says it is using the emptyRenderer, but the items still show up.

I'd really appreciate a push in the right direction.
Thanks.
