Hi,  I'm trying to build custom widget, this is my first steps with this and i have two questions regarding The documentation don't mention about it. Maybe you have some advice or simple examples for me.   1) how to retrive by objects associated with not commited object? Or maybe for this i should use other api call? 2) what can i pass (object, list, variable, single or multiple objects/attributes) to MF executed from and how to do it?

1. If you create the "non-comitted object" from server, I don't think that you could retrieve that from client. If you create it from client, surely you already have it.

2. If you already have the mf to fetch the objects, you could use The callback function should have those objects as parameter. I think this way is easier (since there are examples)
