    [ https://issues.jboss.org/browse/RF-10154?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12575361#comment-12575361 ] 

Martin Kočí commented on RF-10154:
----------------------------------

This problem appears only if project stage is Development, because myfaces use an extra component walk for debug informations collecting:

Caused by: java.lang.NullPointerException
	at cz.aura.faces.richfaces.Snippet.isRendered(Snippet.java:44)
....
at org.richfaces.component.UIDataAdaptor.visitComponents(UIDataAdaptor.java:1280)
at org.richfaces.component.UIDataAdaptor.visitDataChildren(UIDataAdaptor.java:1307)
at org.richfaces.component.UIDataTableBase.visitDataChildren(UIDataTableBase.java:337)
at org.richfaces.component.AbstractExtendedDataTable.visitDataChildren(AbstractExtendedDataTable.java:138)
at org.richfaces.component.UIDataAdaptor.visitTree(UIDataAdaptor.java:1381)
....
at org.apache.myfaces.view.facelets.tag.ui.DebugPhaseListener._doTreeVisit(DebugPhaseListener.java:310)
at org.apache.myfaces.view.facelets.tag.ui.DebugPhaseListener.afterPhase(DebugPhaseListener.java:286)

please note the DebugPhaseListener which is involved. This is done for RESTORE_VIEW phase too and in that case org.richfaces.component.UIDataAdaptor.requiresRowIteration(FacesContext) returns false.

>  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".
