Recording Clips

Hi.
I have created a script that fires a clip with a button press with a condition before firing:

Listeners:
Button was pressed

Block 1
Conditions:
self.song().view.highlighted_clip_slot.has_clip == True
and
self.song().view.highlighted_clip_slot.clip.is_recording == False
and
self.song().view.highlighted_clip_slot.clip.is_playing == True
Actions:
self.song().view.highlighted_clip_slot.stop()
return

Block 2
self.song().view.highlighted_clip_slot.fire()

So that works great – fires (with a button press) to record when clip slot has no clip, fires to play (with a button press) when recording, stops (with a button press) when playing.

But!
That do not work for the first time ableton opens.
At the first time – with empty slot – i press button – clip starts to record and immdiately fires to play. So the clip with minimum length was recorded.

After that – i can work with button fine. I can delete clip – and press to record – i will continue recording unltill the button would be pressed to play clip.

How that issu can be fixed to normal behavior?

Normal behavior is to start recording a clip when empty clip was fired with no immediately fired once again to make clip play.
