complex dat

¿Can I pass a complex data to a Custom Widget? for example a B D M(Bussines Data Model)

Hi all

I am a newbie at Bonita 7.2, my problem is: I have created a custom widget that is a Modal Panel or Pop-up to fill in some data from a BDM called communications and then save it in a BDM, the problem is that the parameters or properties you pass to a Custom Widget, only can be one of a reduced set of types, for example:
text
choice
html
integer
boolean
collection
