Thanks Aleksey, it's it.

I have in the oTsql.Connect(), code:
...
this.cconn=oapp.citajini('Database','dbparm','',oapp.cinifile)
this.nrucka = SQLSTRINGCONNECT(this.cconn,.t.)
...
but, in the CursorAdapter in Init method, i have next code:

This.DataSource = sqlstringconnect([dsn=LocalServerRGZ;trusted_connection=yes]) (CursorAdapter's Builder !!!).

It's error, needs: this.DataSource = oTsql.nrucka
