Re: [T5] GenericSelectModel Problem
you save my life ! I keep thinking that the problem is at the idField (because the error message) , and I does not realize that the labelField is the culprit here ... the name is correct but I didn't hv a getter/setter for the labelField ! troubleshooting for 1 week , finally solved ... hurray, thx thx all ...

Re: [T5] GenericSelectModel Problem
Just a quick hint: check if the name of your bean attributes are correct when you pass it to the GenericSelectionModel (labelField and idField). In my implementation, when the names are wrong, the list shows the toString() method.

Re: [T5] GenericSelectModel Problem
Don't know if this will help your but we had a similar issue (not using the beanmodel though), we used to override toString() in an EnumSelectModel but found this no longer works, the solution was to implement a properties file instead to do the mapping...
