[jira] Created: (TRINIDAD-1078) Application View Cache is broken

Application View Cache is broken 
---------------------------------

                 Key: TRINIDAD-1078
                 URL: https://issues.apache.org/jira/browse/TRINIDAD-1078
             Project: MyFaces Trinidad
          Issue Type: Bug
          Components: Components
    Affects Versions: 1.0.7-core
         Environment: Jdeveloper 10g,
OC4J 10g,
MyFaces 1.1.5,
JSF 1.1
            Reporter: Mark Robinson


The application view cache is broken.  When multiple users are using a site with it enabled and they both execute a query at the same time the environment will allow data from user A's session into user B's session.  This likely made it into production because it's a race condition bug rather than a functional bug.

Execution example:
User A and user B execute a function at the same time which modifies a display table of theirs.
Back-end function runs and updates the DB as expected
User A gets the result they expect(correct rows in the table)
User B also gets the result user A is seeing.

Resolution:
Disable Application View cache in web.xml

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

I created JIRA Issue TRINIDAD-1492 to log an error if USE_APPLICATION_VIEW_CACHE is true. If it gets fixed, this error can be deleted.

(Also see JIRA Issue TRINIDAD-1487 Improve the application view cache)
