Subject RE: PortletBrowseAction.java

I have copied the Jetspeed Development list into the discussion.  This is 
the preferred mechanism for questions of this nature.

In answer to you questions, I am not sure how the Group attribute on 
categories was originally supposed to work.  You assessment of how it should 
work seems plausible to me, but unfortunately, that is not how it works 
currently.  I believe that David Sean Taylor helped with the category 
implementation and may have more insight.

When I wrote the portlet browsing filter functionality, I intentionally set 
it up to work this way.  The reason is that is the way the customizer's 
category filter has worked in the past.  I did not want to change the 
behavior of the customizer filter and did not want to have a filter that did 
not work the same way in the portlet browser.

If you wish to change it, I would suggest doing the following (off the top 
of my head).  Add a new filterPortlets method to the PortletFilter that 
takes a user as a parameter.  Change both CustomizerSetAction and 
PortletBrowserAction to make use of this.

If you do make any changes and wish to seem them incorporated into Jetspeed, 
please create a bug/enhancement report in JIRA 
(http://nagoya.apache.org/jira) and add a patch file with you changes.

Thanks.

Jeremy Ford.
