[jboss-user] [JBoss Seam] - My filtered pooledTaskInstanceList
I needed a filtered version of the pooledTaskInstanceList so that i could select tasks
assigned to a given actor pool.
the two actor pools tasks that i needed were CRS_Releaser and CRS_Processor.
i can use following to get my filtered lists
#{cRSReleaserPooledTaskInstanceList}
#c{RSProcessorrPooledTaskInstanceList}
i dont know how "good" my solution is.... any comments would be nice.
anyway i hope this helps someone else out there.

| }
