Stopping character animation while it is looping

I have a character in a scene which, when entering the room, is in a "sleeping" infinite looping animation, but when the main character clicks on it, it should stop the sleeping animation and switch to a "wake up" animation.

I have tried to do this with the hide animation action, the unload animation, and also using lua directly (stopAnimation(Animations['lisa_sleep']) but nothing seems to work.
The character keeps sleeping forever and the left click to make it switch animation is never registered.

I also tried to set a fixed number of loops on the sleep animation to see if the infinite loop was the problem, but I got the same result - while the sleep animation is running, I cannot interact with the character and make it stop.
When the sleep animation is not running, I can start the wake up animation just fine.
Btw - the animation is set to play without the "wait for animation to finish" flag, but I have tried also with the flag without success.

Thanks in advance, any hint or help would be really appreciated since I am not really sure what I am doing wrong. :S

Create an additional outfit with the character sleeping as the idle animation & the wake up animation inside of the outfits character animations, then swap the outfit back to the default outfit after playing the wakeup animation. Should work ok.

This works perfectly, thank you.
