I've posted a question on the IceFaces forum as follows:
I'm hoping someone can take a look as I'm not sure exactly where the problem lies.
All was working until I tried to put in the OnDemandRenderer of IceFaces.
All help is appreciated in advance!!
While I didn't end up using the OnDemandRenderer I did get resolution of my problems using Seam, Icefaces and Macromedia / Adobe flash components inside tabs and/or panel stacks in icefaces + seam.
For an answer to this please see the following icefaces post:
