Callback function reports timeline passed as a parameter is undefined

[MSCAU 8 Likes (Newbie)]

(I am trying to use two separate timelines for open and close animations. I have two tests set up which have the same error.)

 

I pass references to timelines to my callback functions. When I pass them as timeline instances, the callback function reports that they are undefined. I can work around it by passing the names of the timelines as strings but that is clumsy. What am I missing? You'll need to have the console open to see the errors. They also manifest themselves after a few toggle actions as timelines don't get reset properly.

Hmm. I think it's because at the time I'm setting up the callback for tl4, tl5 hasn't been declared yet and the tl4 callback expects tl5 as a parameter. I'm happy to take suggestions on how best to structure this!

Here is how you can do it so you won't have to pass parameters or even need callback.
