#943: ST_ModEdgeHeal : seem don't working
 Reporter:  aperi2007  |       Owner:  strk         
     Type:  defect     |      Status:  new          
 Priority:  medium     |   Milestone:  PostGIS 2.0.0
Component:  topology   |     Version:  trunk        
 Keywords:             |  

 I try this
 select topology.ST_ModEdgeHeal('topo_test',17, 16);

 where 16 & 17 are two connected edges.

 I guess they must heal, but
 instead i have this response:

  ERROR: TopoGeom 2 in layer 1 (topo_test.linee_topo.topo_geom) cannot be
 represented healing edges 17 and 16

 I attach the image of the relation between these edges.
 The red node are first and last node of the edges.
