    ClassCastException: java.lang.Long when viewing home page.

    Gary Pinkham Newbie

      ok. Apologizes early if I don't post the right info... I checked the forums and the Jira and don't see this issue so I'm betting it's me.. but here goes..

      I used Seam generate-entities to create a bunch of crud pages.. all went well. I have tried this again with the same DB several different times with no luck. It seems to generate the entities just fine, deploys and starts up but when I try to view the home page I'm presented with a "java.lang.ClassCastException: java.lang.Long" I've tried it with both 1.3Alpha (which worked the 1st time) and with 2.0Beta1. I'm using SQL Server 2005 and the SprintA TDS driver.

      Since there is so much code I didn't create I'm really not sure where to look for the issue. So any suggestions would be greatly appreciated. Also note that I had this error on a different entity.. I removed it from the included DB tables.. regenerated and now the next entity has the same issue so I know it wasn't a particular entity.

      Here is the Stack Trace:

            You can't have a minus in the name of a Seam component.

              That was it!! Many thanks Gavin! Now that I know this and I look at the project which worked (knxconfig) and the 4 that didn't (knx-seamui1 thru knx-seamui4) it makes sense to me!

              Thanks again.

                np, its Seam's fault for not validating the name very well

                Would you do me a favor and report in JIRA that Seam should validate component names and eliminate things that aren't valid EL identifiers?

                Thanks
