Compiler error with TMap connections "exposed on spawn"

I get a compiler error when I try to create a widget with any kind of TMap as parameter

a TMap of int,float gives me :
Error COMPILER ERROR: failed building connection with ‘Integer is not compatible with Map of Integers to Floats.’ at Create Widget

I can think of some workarounds by triggering events and handeling them in the parent widget, but passing the TMap would be way easier…
Is this a known issue ? Or am I missing something ?

Probably not implemented yet. Get rid of the expose on spawn and use a set node after you created the Widget for now.

I’m having the same issue, seems like a bug.
