I think you have a misunderstanding of what default datasession means. It doesn't mean the DS in main application (maybe default DS confuses many people the same way). I don't know how would you name it in a better way but think of this:
from that form with a private DS you call a modal form with DS set to default. That 'default' is your form's private DS and not the DS that we have we launch VFP.

Anyway you meant to access to a cursor in another DS, you need to switch. While swithiching you wouldn't use &.

set datasession to thisform.datasessionID

or for others:

lnSession = set('datasession')
* ...
set datasession to m.lnSession

Alternative might be to save result in an ADO stream for example or recordset which you would be able to access from any session and get as a cursor idf you need using CA.
ADO is a simple alternative and there others like XML, array ...
