ST_ModEdgeHeal : test not connected edge

[aperi2007]

Hi,

testing select topology.ST_ModEdgeHeal('topo_test',1, 5);

where 1 and 5 are two not directly connected edge (there are an edge #2 between).

the response is:

ERROR: TopoGeom 7 in layer 1 (topo_test.linee_topo.topo_geom) cannot be represented healing edges 1 and 5

ISO suggest this message: "SQL/MM Spatial exception – Nonconnected edges"
