The frameStyle was unexpectedly null when displaying the trigger in the view to choose trigger panels.
It was good on the stack so I missed that in initial implementation.
Bug showed up once there was another trigger on Beginning of Main Phase, for instance Coalition Relic.
The lack of frameStyle lead to a rendering NPE.
