--------------------------------------
Hi [~sbcd90],
as far as I know, there is nobody working on the issue. However, I haven't seen
any more users except for me who have complained about multiple dimensional
arrays which cannot be used as a key.
If you want to work on the issue, I can assign you the issue.
Cheers,
Till
