[ http://issues.apache.org/jira/browse/MYFACES-985?page=comments#action_12361940 ]
Andrew Kharchenko commented on MYFACES-985: -------------------------------------------- Attached component is just a sample. The real component is a DateChooser which consists with text field, button and popup calendar. DateChooser is extended from UIInput and has popup panel (UIPanel extentor) as child. For one's turn, popup panel has Calendar (UIInput extentor) as child. That's all. In addition, I've tried to move children addition to component's constructor from component's renderer and it helped. So, I think this request can be resolved. Thanx. > 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 > Assignee: Mathias Broekelmann > 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.
