JBO-27122: SQL error during statement preparation

Today Morning, when i tried to run one of my OA page in R12, get into this strange error message : JBO-27122: SQL error during statement preparation.

The sql statement was perfect, just copied the sql statement into the sql developer it works great. Based on my further research found that its bug in the oracle JDeveloper 10.1.3.3.0.

Oracle SQL Developer problem - enter / backspace / delete button not working

I extensevily use Oracle SQL Developer, one fine morning the enter key, backspace and delete button inside the SQL query editor stopped working all of a sudden.

I tried restarting the Oracle SQL Developer, even restarting the computer, but the problem persisted.

so I just went and searched in oracle forums and found the simple solution

To resolve the problem you have to go to:
Tools -> Preferences -> Accelerators -> Load Preset -> Default -> OK
