Symptoms

You developed an ADF application with one "Model" project and multiple "ViewController" projects
(all dependent on the same model).

When you deploy the application to a standalone WebLogic Server 11g (10.3.2), you can access
both web applications.
However, when you then open a second browser session and try to access the two webapps,
one of them now gives a 404 error - it's as if it has disappeared.

It's always the same webapp that becomes inaccessible. Also, when the second browser session
is receiving a 404, the first browser session can continue to access both webapps
(even though one of those webapps returns 404 errors to other sessions).

There is no error added to the WebLogic log files when you receive the 404 error;
however the earlier (successful) attempts to use the webapp are adding the following error to the log:
:

oracle.adf.controller.internal.metadata.xml.MetadataResourceXmlImpl
Transient state added to StateManager.  State may not be serialized.  State id:  yourPageDef.yourVO__dataModel


MDS (MetaData Services) is enabled in your Projects.
