------------------------------
Status: Open (was: Patch Available)
> 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?
