Hi, did you find a solution? I had the same issue. My sql developer version is 3.0 - so oracle suggested that the version is the issue. But i don't have issue with other databases. Please share your solution. Thanks
If you have a question or issue you need help with then create your own thread and post ALL of the particulars of your use case including: full sql developer version, database name and full version and an EXACT set of steps that you use to reproduce the problem.
