Re: [jgrapht-users] Null Edge

[Mohammad I. <msi...@ua...>]

Hello,

I have found the error. Actually I used similar codes earlier and it gave
correct result so I thought that it may be some problem of libraries. I
figured out that I have included JGraph library which was not there before
and NetBeans imported DefaulEdge from JGraph not JGraphT and that was
causing the problem.

Thanks.
