Error with simple triangle adjustment.

Dear Ale=9A,

 i have modified the standard .gkf example to include two fixed points (1 a=
nd 2) and one free point (407) =

 to be adjusted using measured distances (1->407 and 2->407)
=3D=3D=3D
<point id=3D  "1" y=3D" 644498.590 "  x=3D" 1054980.484 " fix=3D"xy" />
<point id=3D  "2" y=3D" 643654.101 "  x=3D" 1054933.801 " fix=3D"xy" />
<point id=3D"407" y=3D"644025.978" x=3D"1054821.167" adj=3D"xy" />
<obs from=3D"1">
   <distance to=3D"407" val=3D "498.750" />
</obs>
<obs from=3D"2">
   <distance to=3D"407" val=3D "388.562" />
</obs>
=3D=3D=3D

This example works as expected, but if if remove the (optional ?) approxima=
te coordinates for point id=3D"407"
=3D=3D=3D
<point id=3D  "1" y=3D" 644498.590 "  x=3D" 1054980.484 " fix=3D"xy" />
<point id=3D  "2" y=3D" 643654.101 "  x=3D" 1054933.801 " fix=3D"xy" />
<point id=3D"407" adj=3D"xy" />
<obs from=3D"1">
   <distance to=3D"407" val=3D "498.750" />
</obs>
<obs from=3D"2">
   <distance to=3D"407" val=3D "388.562" />
</obs>
=3D=3D=3D

then gama-local fails with the "No network points defined" error:

=3D=3D=3D
<error category=3D"gamaLocalException">
<description>GNU Gama - solution ended with error!</description>
<description>No network points defined</description>
</error>
=3D=3D=3D

Is it a bug in the program, or do i misunderstand something ?

Sincerely,
 Oleg.
