Hi Yong,
This issue has come up before on the bridges-dev list and also an JIRA issue
for created:
http://issues.apache.org/jira/browse/PB-41
The current solution is very simple (as I also commented in PB-41).
define "org.apache.struts.taglib.tiles.CompContext" as render-context attribute
in your struts-portlet-config.xml:
<config>
<render-context>
<attribute name="org.apache.struts.taglib.tiles.CompContext"/>
</render-context>
...
</config>
As you can see in PB-41, I'm also working on a transparent solution which will
not need the above configuration anymore.
That solution is mostly ready but pending a little more testing before I'll
commit it.
I plan to have that included in a soon to be released 1.0.1 version of bridges.
HTH,
Ate
