How to Render in AEGP with AE 2015??!!

Hi All,

There is a change in AE 2015 where two separate threads where presented: UI thread and Rendering thread.

Here is my issue:

Let's take a Panelator project as example.

- I've a window with a button.

- The click on this button is recognized as part of an idle hook function

- This idle hook function called within the UI thread.

The question is:

  - If I would like to render as a response to "Click Me" button. How can I do it? 

     Whenever the button action performs any lengthy operation the AE hangs.

Right now, I perform a rendering as a response to the click, but it's not a correct way to work in AE 2015.

So, what is the right way to do it in AE?
