Hi Enrique,

CursorAdapter is bound to the DataSession it is created in and it opens cursors in that DataSession.

CLEAR 
SET DATASESSION TO 1
CLOSE DATABASES all

CREATE CURSOR foo (f1 I)

oCA=CREATEOBJECT("CursorAdapter")
oCA.DataSourceType="NATIVE"
oCA.SelectCmd="select * from foo"
oCA.Alias="test"

LOCAL oSession as Session
oSession = NEWOBJECT('Session')
Set DataSession to (oSession.DataSessionId)

?oCA.CursorFill()
?SET("Datasession"), USED("test")
SET DATASESSION TO 1
?SET("Datasession"), USED("test")

Thanks,
Aleksey.
