Help needed regarding insert a record

Question

Hi,
I have designed a page to insert employee records.
After pressing the "Apply" button is giving the following error :
The requested page contains stale data. This error could have been caused through the use of the browser's navigation buttons (the browser Back button, for example). If the browser's navigation buttons were not used, this error could have been caused by coding mistakes in application code. Please check Supporting the Browser Back Button developer guide - View Object Primary Key Comparison section to review the primary causes of this error and correct the coding mistakes.
Cause:
The view object CreateAM.EMP_Create_VO1 contained no record. The displayed records may have been deleted, or the current record for the view object may not have been properly initialized.
Please help me in resolving this error.
Thanks,
Swaroop

Hi shiv,
I have created a EO attached it to EMP table. Created VO, atteched to that EO.
and My controller code is :
