[jboss-user] [JBoss Seam] - DataModel selection gives wrong value in multiuser/concurren

Hi, My DataModel or DataModelSelection is not behaving properly in multiuser operations. Lets say I have populated a DataModel with 5 entities. Now, I render this list with JSF DataTable on UI (for user 1) At the same time, user 2 starts the application and views the same list with 5 entities. Now user 1 deletes entity 1 from the list and gets the refreshed list with 4 entities. But user 2 does not know about the modification done to the list and tries to view the details of entity 1 (which is not there in the list). But after selecting entity 1 of previous list, user 2 is getting the details of entity 1 of the refreshed list (previously entity 2). How can I solve this problem ? I could think of maintaining a class level variable which would keep a track of modifications to the list (DataModel), similar to what version number does in Hibernate. But that would be a crude way of doing a workaround. Is there any standard way of handling this situation ?
