Have you compared what you have with the examples? Check here:
and the source code is here:
Can you send me your portlets, please?
It's actually not currently possible to graphically edit the coordination information without first "salting" the page coordination metadata with a -object.xml file.
I've opened a JIRA for it: https://jira.jboss.org/jira/browse/JBPORTAL-2288
I am facing a similar problem using the graphical tool as explained in the reference manual for JBoss 4.3.
The problem I am facing is that the
<implicit-mode>tag is not being accepted by the dtd:
http://www.jboss.org/portal/dtd/portal-object_2_6.dtd. It is also not accepting the tag. Please advise on how to use the coordination related tags in the dtd.
Also I want to know that which object.xml should have these coordination tags: source or target portlet??
