Unwanted PAI function code

Hi experts,

I got a dynpro with a Input/output field on it which is set to output field only. There is also one button in the application toolbar with a function code "TEST".

When I double click the output field now, PAI is thrown and the function code is filled with 'TEST'. How can I avoid that?

The output field shouldn't be double clickable at all or at least throw a PAI with an empty function code.

Thanks in advance.

Regards,

Tobi
