i have a problem in a WD application, when i execute a certain RFC, the model node in the controller mapped to that RFC (model), does not fill itself with the data that the RFC suppose to bring as a result. it seems to get lost in some point (the data). i check and all seems to be fine. I bind the node, then i execute it and later i invalidate it. It's not a role problem i've checked already, and the RFC in the backend when i run it, shows me data. Anyone knows what could this be?...
