Thanks! I wrote an exporter based on your script!

Also Ridiculous that is the only decent solution to get selected groups name.
Indeed browsed photoshop PDFs and found nothing for it.
1000 thanks for it! :)
Thanks very much for the solution - worked perfectly!
Regarding the comments about this not being supported via the API - at a purely practical level I agree, and it's annoying that you have to resort to a mixture of grouping trickery and Script Listener output to make this work. One should be able to perform this sort of operation without modifying the state of the underlying document (even temporarily) - it's just a query.
Speculatively: it's implemented this way because the PS API reflects how Photoshop internally thinks about the document. You can't edit more than one active ArtLayer at the same time, so the concept of "selected layers" doesn't really make sense to the underlying system - which the API ostensibly exposes.
Not sure if Adobe provides a script interface to the PS UI, which (if my guess above is correct-ish) would be the place to find / implement this kind of functionality.
Why grouping the layers and then regrouping, doesn't that slow down the script?
One thing, the script's name isnt correct I believe. SInce this groups layers, why not name accordingly.
PS why is that undo() in that loop?
Thank you for sharing this with us!
I'm always intrigued by these mysterious charID / actionDescriptor / executeAction snippets. They always look so machine-generated to me. How do you come up with these seemingly random method parameters? Is there a way to somehow export this from Photoshop/actions?
Thanks,
Peter
Hi @peterceluch- I guess you already found this by now, but anyway - get xtools scripts here (http://ps-scripts.sourceforge.net/xtools.html).
These allow you to convert recorded actions into javascript. From there you can modify the code into useful functions with custom parameters and reuse at will.

Thank you very much, @Picazsoo - I did not know about that!
Thanks for this. It's pretty ridiculous that Adobe didn't provide a simple function that would do this considering how important this kind of thing is for scripting
