Hello everybody!

I use tacos:Tree for displaying tree-view structured data. I have few problems 
and questions about it.

1) We will run our application under WebSphere portal, but we have doubts if 
Ajax will be work in portals at all and in WebSphere portal especialy. Does 
anybudy use tacos components in portals? Maybe it's better to find another 
solution for our problem?

2) !!! If the answer for first question is possitive !!!
I can not submit form with tree, because I get following exception: 
_________________________
Component IvrMenuTreeBuilder/linkNode requires rendering support, but no 
PageRenderSupport object has been stored into the request cycle. This object is 
typically provided by a Body component. You should add a Body component to your 
template.
_________________________
linkNode is a component of AjaxDirectLik type.

In portal we can not use Body component. Is there any other way to do possible 
using AjaxDirectLink?

3) Every time I egt following warnings:
Error performing ajax enhancement on component classorg.apache.tapestry.form.
Submit
InjectAjaxComponentRenderWorker [WARN] Error performing ajax enhancement on 
component classnull
InjectAjaxComponentRenderWorker [WARN] Error performing ajax enhancement on 
component classorg.apache.tapestry.link.DirectLink
InjectAjaxComponentRenderWorker [WARN] Error performing ajax enhancement on 
component classnet.sf.tacos.partial.PartialForeach

etc.

What does it mean?
(I'm using tacos4-beta3 version of tacos library)
