Could you post some of the XHTML code? Also the full error from the duplicate component ID may be helpful. That component path should directly indicate which component is getting the error (it is in a dataTable, and doesn't have an ID assigned to it).
Also if you are using facelets includes, you have to make sure that IDs are unique for the entire component tree, not just the include. So if you have: <ui:include src="a.xhtml" /> <ui:include src="b.xhtml" /> the component IDs in a and b have to be unique. Since you are having an issue with an auto-generated ID in a data table, I'm inclined to think it is a component binding issue though. On 5/23/07, SiSi'mon <[EMAIL PROTECTED]> wrote:
Thanks, I am not quite sure I understand everything in the article. We have ID's on every component in the xhtml. Not sure how to implement the suggestion for not using session scoped beans.
