Sorry, I do not have look into the code deeper. It should work, but you should care in you case about the following:

The expression:

 datastr : childStr[row_id-1]

Can not be evalueted good - I think the better way will be:

 datastr : childStr[parseInt(row_id,10)-1],

The reason for this is the row_id is interpreted as string and not as number.

Currently subgrid does not accept xmlstring and jsonstring parameters.

I will try to correct this in final 3.4 release

Thank you

Regards
