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

             Summary: FacesContext.getCurrentInstance().getPartialViewContext().getRenderIds() return immutable when empty
                 Key: TRINIDAD-2387
                 URL: https://issues.apache.org/jira/browse/TRINIDAD-2387
             Project: MyFaces Trinidad
          Issue Type: Bug
    Affects Versions: 2.1.0-core
         Environment: Windows Vista
            Reporter: Clément
            Priority: Blocker


I'm facing an "UnsupportedOperationException" when trying to add a dynamique Id in RendersIds of partialViewContext (FacesContext.getCurrentInstance().getPartialViewContext().getRenderIds().add("MyCompId");).

As Balus C said : "It appears that FacesContext.getCurrentInstance().getPartialViewContext().getRenderIds() returns Collections#emptySet() when there are no render IDs. This is however immutable! This totally explains the exception you're facing.(...) The javadoc clearly says that the returned collection must be mutable."
