Duplicate id problem
---------------------
Key: TOMAHAWK-454
URL: http://issues.apache.org/jira/browse/TOMAHAWK-454
Project: MyFaces Tomahawk
Type: Bug
Environment: Windows XP, Eclipse 3.1, MyEclipse, Tomcat 5.0.28
Reporter: Sreedevi
I am using myfaces tomahawk and tiles to design an application.
In one page i have a panelgrid with a listbox that contains a list of items,
and the selected item should be moved to the right list box on click of the
move button. This happens without any error. I'm doing server-side validation
to check if the right listbox is empty. if i don't select any item and submit
the page, the error is displayed on the page. But if i subsequently try to add
an item to the right side list box i get the foolowing error:
javax.faces.FacesException: ServletException in '/example/tilesLayout.jsp':
ServletException in '/pm/PmProfileAdd.jsp': cannot add component with id
'select' and path : {Component-Path : [Class:
javax.faces.component.html.HtmlPanelGrid,Id: select]} to its parent component.
This might be a problem due to duplicate ids.
How do I fix this problem?
