UIDataAdaptor vs. UIData visitTee small difference
--------------------------------------------------
Key: RF-10154
URL: https://issues.jboss.org/browse/RF-10154
Project: RichFaces
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: component-tables
Affects Versions: 4.0.0.Milestone5
Environment: RichFaces 4.0.X trunk, svn rev. 20913
Reporter: Martin Kočí
Assignee: Nick Belaevski
Priority: Minor
Fix For: 4.0.0.CR1
<r:extendedDataTable var="zeile">
<r:column>
<h:outputText rendered="#{fasole.method(zeile)}"
</r:column>
</r:extendedDataTable>
+
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".
