Error when clicking Enter Button.

Question

Hi,
I have a BSP page with one input field and one submit button.If i place the cursor on the Input field and click Enter button, Im getting the following error:
<b><i>
500 SAP Internal Server Error
Error message: Access not possible using 'NULL' object reference. ( type of termination: RABAX_STATE )
</i></b>.
if i add one more input field im not getting any error msg...and it is fine.
Is it problem with one input field.
