libgdx disable touch while action is ongoing

Question

I cannot figure out, how to temporary disable the DragListener while there is an ongoing Action on the Actor. When I touch the Actor while there is an ongoing Action it gets interrupted and the new Action is executed, which leads to a "drift" of the Actor. e.g. I shake the Actor, but when it is interrupted, the following Action is based on the interrupted position of the Actor.

Adding Actions inside touchUp method:

RotateByAction rotL = new RotateByAction();
rotL.setAmount(-3);
rotL.setDuration(0.05f);

RotateByAction rotR = new RotateByAction();
rotR.setAmount(6);
rotR.setDuration(0.05f);

RotateByAction rotBack = new RotateByAction();
rotBack.setAmount(-3);
rotBack.setDuration(0.05f);

SequenceAction seq = new SequenceAction();
seq.addAction(rotL);
seq.addAction(rotR);
seq.addAction(rotBack);

temp.setOrigin(temp.getWidth()/2,temp.getHeight()/2);

temp.addAction(seq);

I tried to do something like this inside the Render method of the Actor:

if (this.getActions().size > 0){//or hasActions()
            this.setTouchable(Touchable.disabled);
        }
        else{
            this.setTouchable(Touchable.enabled);
        }

But that leaves the Actor untouchable!

What you should do instead is use Actions.touchable to disable touch at the start of your action and then enable it again at the end. You can also string multiple actions together, using sequence or parallel.

temp.addAction(Actions.sequence(
    Actions.touchable(Touchable.disabled),
    rotL,
    rotR,
    rotBack,
    Actions.touchable(Touchable.enabled)
));
