[jboss-user] [JBoss Seam] - My filtered pooledTaskInstanceList

[harpritt]

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.

  |     private List pooledTaskInstanceList;
  | 
  |     //could make this filter on more than a single actor..really this is a group

  |     @Factory("cRSReleaserPooledTaskInstanceList")
  |     public List cRSReleaserPooledTaskInstanceList() {

  |         List taskInstanceList = new ArrayList();

  |         while (pooledTaskItr.hasNext()) {
