JBO-25080 while working with Data Controls
There is a know error while using Data Controls with the same name as packages like same minutes ago this ocurred to me: My package is named xpto.jobhistory and the entity is named JobHistory (case insensitive bug), by default my Entity Data Control reference was named with JobHistory.xml. This situation lead me to a bug when running the .jspx page, these JBO-25080. Hope it helps!
