> org.richfaces.component.UIDataAdaptor.visitTree(VisitContext, VisitCallback) with VisitHint SKIP_UNRENDERED (in render response phase for example)
> Problem: org.richfaces.component.UIDataAdaptor.visitDataChildren(VisitContext, VisitCallback, boolean) calls visitComponents(getFacetsAndChildren(), visitContext, callback);-> it will visit h:outputText component and test if is rendered -> #{fasole.method(zeile)} but no row available -> calls fasole.method with null parameter and causes an unexpected NPE
> j.f.c.UIData does not visit column chidren for -1 rowIndex (null rowKey in RichFaces), UIData.visitTree JavaDoc says: "Take no action on non-UIColumn children".
