In day-to-day use JDeveloper always make some weird things by itself... Here I'am showing how to solve the most common one, the Data Control Palette got hidden somewhere in the darkness... Screen showing the Palette: Altough I was not able to reproduce the problem I know how to solve it, you just have to go to Window Menu and click "Reset Windows to Factory Settings", that'll fix some lost tag in one of JDeveloper configuration XML's.

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!
