Can't get a simple button working
Feeling pretty dumb here... I'm trying out the App Editor, and I've made a button which receives some data and calls a Python script which prints the data... and that's all! And when I click this button it calls the Python script, but then it never comes out of the "Loading" state. I've tried returning True from the Python script, I've tried attaching a Transformer to do 
myButton.loading=false .... I just can't figure it out. There must be something very basic I'm doing wrong
