Send <column> tag instead of <coll_options>

Hello,
I want to load a grid with 2 combos in 2 columns and the second column should have values based on the first one. To do that I read in the documentation that getCombo() can be used to get combo object and edit it. The problem is that that object is always empty and I think it’s because there’s no tags in XML sent by Connector. Apparently the object doesn’t recognize <coll_options> tag.
So my question is: is there a way of sending based instead of <coll_options> based XML automatically by the GridConnector?
if there isn’t a way, how can I change options on request?

The coll_options must work fine with combos in grid, can you provide a snippet of xml and js code which is not working in your case.

my bad, I was trying methods related to combo excell while using coro excell (like loadXML)
my apologies :wink:
