Cascading dropdown problem

[poni]

Hi!
I made one extra group (objekt's) , and join it with it's element in one form which have it's own group (contract's) and element's.Group "objekt's" has own parent_id.Turned on "merge rows", and tried connect with data in one another table , but cascading dropdown with element in joined group evidently not works.Cascading dropdown in "domestic" group works fine.How can I solve this problem.Excuse me for my frequently appearance,but I must work.
BTW.How many cascading dropdown elemet's may I have in one form (or list).
Thanks!

Unfortunately, so must we, and we really can't provide the level of support you need for free.

I'm joking with that ",but I must work" .Question is not for commercial purpose.
Anyway thanks!
