[jira] [Commented] (MYFACES-3144) [PERF] Cache renderer in
UIComponentBase

Jakob Korherr commented on MYFACES-3144:
----------------------------------------
> Is there any method which is always called as first if component will executed/rendered?
MyFaces internally yes, but if you use extensions for custom JSF comp-libs it might be different. We should not rely on an invariant like that!
