Conversation (Access) is lost when jsf validation fails
-------------------------------------------------------
Key: ORCHESTRA-28
URL: https://issues.apache.org/jira/browse/ORCHESTRA-28
Project: MyFaces Orchestra
Issue Type: Bug
Components: Conversation
Affects Versions: 1.1
Reporter: Stefan Glase
Priority: Critical
I am loosing my conversation the bean CategoryController is in, when
required-validation in the view fails.
Without further investigation it looks like it can be explained in the
following way: Orchestra uses a proxy-class to notice calls to
bean-methods,-getters or -setters while in the conversation and when there is
no direct access to the bean from the view, the access scope will be lost.
That is fine in standard cases but when calls only go to the extending class
this behaviour should be considered wrong.
