Exception Class CX_SY_REF_IS_INITIAL - Dereferencing of the NULL reference

Hi Exerts,

I have enhanced one view and did some modification to remove one button. Now when I go to UI and go to transaction then without adding any value if I press Cancel button then I get followin error:

-

Cannot display view TPMOE/VtsEOL of UI Component TPMOE

An exception has occurred Exception Class CX_SY_REF_IS_INITIAL - Dereferencing of the NULL reference

Method: CL_TPMOE_VTSEOL_IMPL=>DO_PREPARE_OUTPUT

Source Text Row: 124

I checked the code and the entity is empty while calling one of the method. But that piece of code I did not touch.

Any suggestion why is it appearing?

Cheers,
