Max Starets commented on TRINIDAD-2369:
---------------------------------------
This issue is a manifestation of TRINIDAD-2368. Because teh REMOVE event is not
fired when the component is moved out of the facet, Mojarra's partial code
sees two consequitive ADD events for the same component.
> Mojarra 2.1.18 partial state saving incompatibility when moving a facet
