Subject [jira] Created: (JS2-509) Portlet Preferences are not stored on a user by user basis
Date Thu, 09 Mar 2006 17:56:39 GMT
Portlet Preferences are not stored on a user by user basis
----------------------------------------------------------

         Key: JS2-509
         URL: http://issues.apache.org/jira/browse/JS2-509
     Project: Jetspeed 2
        Type: Bug
  Components: Portlet Entities and Preferences  
    Versions: 2.0-FINAL    
 Environment: Tomcat 5.5, JDK 1.5, Jetspeed 2.0
    Reporter: Aaron Evans


Portlet Preferences are not stored on a user by user basis.

Looking in the database, it looks as though the preferences are being associated with the
fragment ID for the portlet of the psml page.

I am pretty sure that the intention of the portlet spec is to enable the storing of preferences
on a user by user basis.  But apparently this is not possible in jetspeed unless the user
creates a new portal page?

The data I see in the DB seems to support this:

I login as user A, and I have a portlet preference  for one of my report portlets called reportTimeZone.
 By default is set to US/Eastern.

User A edits his portlet preferences and sets the reportTimeZone to be US/Pacific.

Looking in the prefs_property_value table, can see the newly created value.  It has node ID
2875 and value US/Pacific.  The property name is 0, I assume that this is the index in the
array if it were multi-valued.

I then look in the prefs_node table for a row with node_id=2875.  The row is present and the
full path of the node is:

 /portlet_entity/reports-3/no-principal/preferences/reportTimeZone/values

Note that reports-3 is the fragment ID for the portlet fragment in the psml page.

However, instead of 'no-principal', I would have expected to see the user name of user A.

So now I log in as user B and go to edit my portlet preferences and the value of the reportTimeZone
preference is set to US/Pacific, not the default US/Eastern I would have expected.

So I then, as user B, set the reportTimeZone to US/Central and update my preferences.

Sure enough, it overwrites the value in the prefs_property_value table to US/Central.

So, in order to get the behaviour I need, I would have to generate portal pages for each user
and vary the id of the portlet fragment?   This does not seem like a good solution to me.


Further, in my environment, users are not permitted to create their own pages and customize
them. I am simply providing a form in the doEdit method of my portlet to allow users to customize
the behaviour of the portlet.

So, in my environment, imagine I had a weather portlet on a portal page.  If someone sets
their preferred city to be Bangkok, then *all* users will get weather for Bangkok!

This does not seem right to me...
