When selected any item in listbox, my screen objects will be refreshed

[acamli]

Hi everyone,

I have one program about screen and dynamically changed objects.

If I select any value in listbox, my screen will be refreshed and my listbox items will duplicated.

How can I fix that?

Thanks.

      hane1_list TYPE vrm_values,

      hane2_list TYPE vrm_values,

Where did you refresh internal table hane2_list?

[acamli]

hane2_list is not important me. IF I select any value in hane1_list, hane2_list show demo data for me.

But when i select a data in hane1_list, my screen will be refreshed, my selected value will be nulled and hane1_list values will be duplicated.

I don't understand your exact situation, also possibly you have assigned an incorrect data type to your dynpro field.

As you say that "hane1_list values will be duplicated.", sorry to insist, but where did your clear your internal table hane1_list? (logical sequel to Raymond question)
