PlayThread and setActionThread

Hi there!

Not sure how to fully explain, but here's what i'm trying to do:
1. Move my toon around the map, it has the run animation.
2. I collide with an item, the toon should then play an animation once.
3. When finished playing, toon should go back to the run or idle animation.

My problem is that when i set the animation with playThread() it plays instantly, no blending, and then when the animation has finished the idle animation of my toon is...well messed up.

I play the animation like this:

function Player::playThreadOnce(%this, %anim, %animLen)
{
	%this.playThread(1, %anim);
	%this.schedule(%animLen, "stopThread", 1);
}

Note that i'm a beginner so i really don't know if this is correct... =/

Anyway, after i have called this function i call a function:

%this.schedule(3000, "stopEatAnimation");

...which basically just says:

%this.playThread(0, "root");

When all this is finished the idle animation of my toon is wrong and it also seems halted...

Ok, not sure i'm making myself understood here.. ;)
I belive it resembles of a soldier running, then when shooting he switch to the shoot animation, and then when finished continues with the run animation...

Is there some way to "push" a thread onto another, making it play that one instead, and when it is stopped it continue playing on the underlying thread...?

I've searched around the forums and resources from quite some time now but havn't found any answears to what i'm looking for...

I am very grateful for any help that might shed some light on this...

Thanks in advance!
