ABAP Function call + strange behaviour

Hello Friends,

I am facing strange behaviour as follows:

I have three input fields with f4 help. I have set EVS in wdinit method of view. ( call RFC function to retrieve the table which i display as f4 help ). so far is okey,

Then some other businss logic implemented which will add more contents in table, thus I again call the RFC to retrieve the new records, ( and in debug mode I can see that the backend gave back the new records ) but when I read the output node, its empty...

any idea what I am doing wrong ?

its more or less same coading which i once call in wdinit, and later in one plugin method .....

Regards,
