FBI Freestyle Helper Sample Implementation

Hi Guys, I´m looking for sample code to implement the   /BOFU/CL_FREESTYLE_BOPF_HELPER class inside a Freestyle GUIBB  Component added to enhance EHHSS_INC_REC_GAF_V3 FPM Application.

I tested a simple enhancement to the business object  ehhs_incident, and I had good results adding some fields to the screens, but I wan´t to develop a some Freestyle GUIBB  WDA components to have more control over the logic and data.

I don´t know how to instance the model api to read or write some data.

My Freestyle GUIBB Component:

Enhancement of EHHS_INCIDENT Business Object:

Added Freestyle GUIBB:

Result "the embedded GUIBB Freestyle Component", but I don´t know how to access model data of the business object layer:

I appreciate some advice, thanks!!!
