var and varStatus of the UIXCollection stay around during a visit tree call
---------------------------------------------------------------------------
Key: TRINIDAD-1919
URL: https://issues.apache.org/jira/browse/TRINIDAD-1919
Project: MyFaces Trinidad
Issue Type: Bug
Components: Components
Affects Versions: 2.0.0.3-core
Reporter: Andrew Robinson
Assignee: Andrew Robinson
A short-coming of JSF is that there is no provision for resetting the component
environment when the context changes during an invokeOnComponent or visitTree
call. For example, the collection family components in trinidad inject a var
and varStatus variable into the request scope when they are iterating. These
variables are left on the request scope if a visit tree or invoke on component
call is made while the collection is in scope.
I propose to make a change to Trinidad to introduce a new API that components
may interact with that is basically a stack. The idea is that components that
make context sensitive changes would push an object onto a change stack. During
an invoke on component call, or a visit tree call, the stack of changes would
be suspended. Once the invoke on component or visit tree call is complete, the
changes could be resumed.
This way, in the table example, the var & varStatus could be removed during an
IOC/VT call and restored after it is complete.
