Blueprint Interface not working with UMG
I thought I knew how to use a Blueprint Interface but apparently not. I've got a main widget with a child widget of a search field.
I created an interface with a function called FirstNameSearchCommitted then inside my search field widget I add the interface and then call the FirstNameSearchCommitted function with an interface call.
Inside my parent widget, I create the event for FirstNameSearchCommitted and run a simple print string but it never fires.
I've noticed that the target pin for the interface call is a faded yellow/green which I've never seen before (normally it's blue) but I can't seem to plug anything into the target slot so I just left it as self, which I thought would work.
Anyone know what I'm doing wrong?
How else would you communicate with a parent widget from within the child if you don't always know what the parent will be?

You do need a target for it. If the child widget implements the interface, then place a reference to the child widget and pull off from there to create the FirstNameSearchCommited node.
