Hi Fabio!

Normally when i must to execute some method of a form or a datasession object from another session i pass an extra parameter to that method, and that parameter is the datasession to use. So, in the method i save the datassisonID of method's owner, so i set the new datasession and after all i restore the original datasessionid.

If you can't change the parameters on your method you could test a public variable (*BLEAH*) or a Common datasesisonproperty attached to _screen.

Sorry for my bad English 8)... i write better in italian.

PS: Your e-Mail address is ok ? because i tried to contact you but i never received a response.
