[ http://issues.apache.org/jira/browse/MYFACES-985?page=comments#action_12361830 ]
Mathias Broekelmann commented on MYFACES-985:
---------------------------------------------
what version of myfaces do you use?
> UIData with multihierarchical children inside produces NPE
> ----------------------------------------------------------
>
> Key: MYFACES-985
> URL: http://issues.apache.org/jira/browse/MYFACES-985
> Project: MyFaces
> Type: Bug
> Components: Implementation
> Environment: Tomcat 5.0
> JDK 1.4
> Reporter: Andrew Kharchenko
> Attachments: UIData NPE Sample.rar
>
> I've found incorrect UIData behaviour under MyFaces which produces NullPointerException on runtime and which works fine under Sun implementation.
> Here it is:
> I have a custom component which is extentor from UIInput. This component has UIPanel extentor component as child which is added to children list of UIInput component on rendering.
> For one's turn, UIPanel extentor has one more UIInput extentor component as child which is added to children list of UIPanel component on rendering.
> This component works fine standalone, but when it is added to UIData, I have NPE on runtime. Here is the part of listing:
> java.lang.NullPointerException
> at javax.faces.component.UIData.restoreDescendantComponentStates(UIData.java:223)
> at javax.faces.component.UIData.restoreDescendantComponentStates(UIData.java:235)
> at javax.faces.component.UIData.restoreDescendantComponentStates(UIData.java:235)
> at javax.faces.component.UIData.restoreDescendantComponentStates(UIData.java:235)
> at javax.faces.component.UIData.setRowIndex(UIData.java:178)
> I will also attach sample component's classes, definitions and test page if it will be granted after issue creation.
