[pgrouting-users] Shortest Path TRSP

[Max Weninger]

Hi again

Ok this is strange. Since the soure vertex is already
checked before the trsp is called. The message you
described comes directly from the C++ impl. of trsp
where it is checked again

Does the values of your source and target columns start from 0?
Since if this is not the case some "renumbering" is done internally
Maybe there is a bug. 

Regards
