Thank you for your answers. The solution works for that case. But my real case it's different and the bug with the range slider OnChange event block me.
I've attached the new oml with Screen2 (the workaround) and with a button that execute a JS interval. If you start the debug, you will notice that the OnChange event is called every second. You also can see that if you move the second slider, this return to the initial value each second.
Therefore, I need to notify this to OutSystems, how can I do it? vía support ticket?
