[Jung-support] EdgeBetweenness for directed graph

[Frédéric V. <fre...@mi...>]

Hi all,
When trying to apply EdgeBetweenness clustering algorithm on a directed 
graph, two things happened :
1) when removing edge by coloring it in light gray, the predicate colors 
strokes, but also removes arrows : how can I add it back ?
2) when slidding the number of edges to remove, for example 10, the 
algorithme remove 11 edges, making my app crashing, with a 
IllegalArgumentException (Invalid number of edges passed in)
The second thing seems to be linked with the fact that it's a directed 
graph, because when I transform my graph and make it undirected, all 
works fine, like in the demo ...

I really don't understand, and tried a lot of thing ...

Thanks for your help !

Fred
