Hi Experts,

I am new to FPM  and I am working on LIST UIBB.I am following SAP technical.com link

http://saptechnical.com/Tutorials/WebDynproABAP/GUIBB/List.htm

In step 32, after giving the feeder class and press on OK button , i am getting dump as follows.

" Access Via 'NULL' object reference not possible.

kindly let me where the error  occured.

Best regards,

Narasimha.

Hi Narasimha,

I think bug is in your GET_DEFINITION method , or your implemented interface IF_FPM_UI_BUILDING_BLOCK methods are not active.

Hope this is fine.

Thanks & Regards

Hi Gupta,

Thank you. The problem occured in GET_DEFINITION method.

Since i have not assigned itab to field catalog properly, i am getting this error.

eo_field_catalog ?= cl_abap_tabledescr=>describe_by_data( itab ).

Thanks & regards,

Narasimha.

Hi,

I sometimes have this issue when I change feeder class before removing columns in the configuration.

Do you modify configuration and feeder class several times?

If yes, finish your feeder class and start a new configuration over.

Best regards,

Guillaume
