Application objects which can be wrapped must not access public methods
internally
----------------------------------------------------------------------------------
Key: MYFACES-2787
URL: https://issues.apache.org/jira/browse/MYFACES-2787
Project: MyFaces Core
Issue Type: Bug
Components: JSR-314
Affects Versions: 2.0.1-SNAPSHOT
Reporter: Jakob Korherr
Assignee: Jakob Korherr
Some time ago there was an issue with Trinidad that was caused by a wrapper
which added some functionality to the standard implementation (MYFACES-2641).
The problem was that the standard implementation (of ViewHandler in this case)
used other public methods internally via this.method() instead of invoking them
on the wrapper. Thus the wrapper was circumvented which led to loss of the
additionaly functionality.
I now finally took a look at all those affected classes and found some similar
issues, which could cause problems in wrapped environments. One of them is in
ViewHandlerImpl when getting the ViewDeclarationLanguage via
this.getViewDeclarationLanguage(). This should be done by
facesContext.getApplication().getViewHandler().getViewDeclarationLanguage().
