Hi all,

I've been trying to create a custom column in Calibre that displays the virtual libraries to which each book belongs. I want to do this so I can see/use my virtual libraries in Calibre Companion.

I've followed these instructions exactly: http://cc_faq.multipie.co.uk/index.php?solution_id=1023

But it keeps resulting in this error:

Code:

#collection:"=TEMPLATE ERROR maximum recursion depth exceeded while calling a Python object"

After trying it out a few times (and variations based on what I read in the manual on templates), I decided to try the option "Column built from other columns" (without the "behaves like tags" part) and..it worked! I don't understand!

It would be better if I could get this custom column to behave like tags (so each combination is not treated as separate). Am I missing something here? I used the exact same template function. Not sure why I can't get it to work.

I'd appreciate any help or advice!
