Hi everybody,  
  
With pgdjektra postgress module i'have some problems with our   
postgis datas.  
  
When i insert datas in postgis after i create 3 new column source_id target_id   
and edge_id... after i run assign_vertex_id function but when i try to run   
create_graph_tables function i obtain the seguent error:  
  
ERROR:  una chiave duplicata viola il vincolo   
"prova_route_2_edges_source_key" (key duplicated)  
CONTEXT:  SQL statement "INSERT INTO prova_route_2_edges (id, source, target)   
VALUES (50, '44', '45')"  
  
because in prova_route_2 data table i have not only a unique source_id   
target_id combination but more.  
  
I obtain the same error with very fine tollerance value in assign_vertex_id   
function  
  
the_geom column if MULTILAYERSTRING.... and SRID -1 
 
with some data (not more rows like 376) i don't have problem, is there a 
limitation in the numbers of rows? 
 
Can you help me?  
  
All the best   
Walter
