ORA-00972: identifier is too long

Hi there, we just upgraded from 2.5.8 to 3.3.2, and getting the following error com.mendix.core.CoreRuntimeException: Exception occurred in action '{"amount":20,"sort":[{"direction":{},"memberName":"List.ListAppEntityMxObjectType/MxModelReflection.MxObjectType/Name"}],"formName":"List.ListOverview","returnsCount":true,"offset":0,"type":"RetrieveXPathSchemaRawAction","xpath":"//List.AppEntity"}', all database changes executed by this action were rolled back at com.mendix.core.actionmanagement.CoreAction.c(SourceFile:493) Caused by: d: An exception has occurred for the following request(s): fn (depth = -1, amount = 20): //List.AppEntity Caused by: d: Exception occurred while retrieving data. (SQL State: 42000, Error Code: 972) Caused by: java.sql.SQLSyntaxErrorException: ORA-00972: identifier is too long As you can see from the exception above, we've got a module called List and this in turn has an entity called AppEntity. AppEntity has an association to MxObjectType in the MxModelReflection module. When we add the AppEntity entity to a grid, and browse to it, we get this error. The Grid only has one column which is the MxObjectType's Name attribute. Any ideas? Kind Regards Frikkie

This happens for Oracle when the complete name of some identifier is more than 30 characters long. However if a name turns out to be too long as is likely in your case (List.ListAppEntity_MxModelReflection.MxObjectType or something) the runtime server will shorten the name so it fits, so I'm not sure why this error occurs.

If you can reproduce this issue in a testproject we'd like to see it.
