Custom cost crash #2

Closed laurensversluis closed 7 years ago

laurensversluis commented 8 years ago

When I use custom cost the analysis freezes at 50%. At one point QGIS crashed after a long wait. The cost column in the network layer has a feature with value 0. Could this be the cause of the problem? Are you by any chance dividing by the cost value? I know several network algorithms break if cost is 0, e.g. pgrouting or igraph.

This is not the case any more. I tested with a custom cost column with 0 (zero) and NULL values and it concluded the analysis.
