Description

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."
