Hello,
I have bug with this behavior in Construct 2 r229
In Construct 2 r226 all works great, but in r229 I have error at "Button click":
Javascript error!
TypeError: this.getCurrentEventStack(...).current_event is null
http://localhost:50000/preview.js, line 3787 (col 17)
This may be a bug in Construct 2 or a third party plugin or behavior - please report it to the developer following the bug report guidelines. Subsequent errors will be logged to the console.
