Since my application has limited database access, I thought not to bring any ORM like hibernate instead use bit of JDBC. Also we are using javax.faces.component.UIData & its getRowData() method to map the table row between UI & managedbean
I don't know to which JIRA I should report this. Kindly help -----Original Message----- From: Mike Kienenberger [mailto:[EMAIL PROTECTED] Sent: Wednesday, October 24, 2007 10:20 AM To: MyFaces Discussion Subject: Re: <t:dataTable> not coming up If it worked in Sun JSF RI and doesn't work in MyFaces (of the same version -- 1.1 vs 1.1 and 1.2 vs 1.2, not 1.1 vs 1.2), please open a JIRA issue. It should work in both places. I don't know how many people really use ResultSets directly with UIData components. I know that I never do this as I always work with an ORM rather than JDBC. So it's possible that the ResultSet model code hasn't been as well tested as other models.
