Creating .as class in Flash Builder for movieclip stored in SWC

[Palladian]

I need to use movieclips created in Flash Professional CC in my Flash Builder project. I have exported my .fla file as an .swc and included it in my Flash Builder project. The movieclips for which I DON'T need a custom .as class import without a problem. But the movieclips that need to be linked to an .as class don't appear. I have tried the following, using my ThoughtBubble movieclip as an example:

1) Giving the .fla with the ThoughtBubble movieclip access to ThoughtBubble.as so that the movieclip doesn't create a dummy ThoughtBubble.as file.

2) Denying the .fla access to ThoughtBubble.as so that the movieclip is forced to create a dummy ThoughtBubble.as class.

Either way, the ThoughtBubble movieclip does not appear in the list of movieclips in my swc when imported into my Flash Builder project.

3) I also tried removing my ThoughtBubble.as file from my FlashBuilder project and THEN importing the swc. The ThoughtBubble movieclip does show up in the list of swc assets--BUT when I try to create a ThoughtBubble.as file, I get the following error: "ThoughtBubble.swc already exists."

What am I doing wrong? How can I link my ThoughtBubble movieclip with ThoughtBubble.as in Flash Builder?

Here is a screenshot of my fla publish settings:

And a screenshot of my ThoughtBubble movieclip properties:

Thanks in advance!
