Clément created TRINIDAD-2387:
---------------------------------
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."
