[jboss-user] [JBoss Seam] - Session scope causes ArrayIndexOutOfBoundsException

[sysex]

Looks like a bug. I'm not a contributor or anything. Should this be added to JIRA?

This error came up when I first viewed my home page (containing a bean using the @Scope(ScopeType.SESSION) annotation) using Firefox, then switched to a new session with Konqueror hitting the same page.

----------------------------------------------------------

The code says:

   public String[] getNames()

   {

      //yes, I know about the toArray() method,

      //but there is a bug in the RI!

      Set keySet = map.keySet();

      String[] array = new String[ keySet.size() ];

      int i=0;

      for (String key: keySet)

      {

         array[i++] = key;

      }

      return array;

   }

-------------------------------

Guess this bug in RI is causing a bug in Seam. 


By the way, this didn't seem to cause any problems in rendering the page.
