System.ArgumentException in LinkRouter.RouteLinks()

When calling TheFlowChart.LinkRouter.RouteLinks(linkCollection) I am sometimes seeing the following exception (with stack trace):

Quote:
System.ArgumentException: Unable to sort because the IComparer.Compare() method returns inconsistent results. Either a value does not compare equal to itself, or one value repeatedly compared to another value yields different results. IComparer: 'MindFusion.Diagramming.NeighborComparer'.

I think that was a breaking change in .NET 4.5, and our developers rewrote NeighborComparer for one of the recent Flowchart.NET releases. You could either build for older .NET versions, upgrade to latest version of the control, or I could send you our current NeighborComparer code if you have the source code.

I hope that helps,
Stoyan

We are going to upgrade to the current beta, once it is out of beta, or a version after that. If the fix is in there we should be okay..

Hi,

Could you send the code of the update NeighborComparer ? That would be very helpful.

Thanks

Hi,

This offer was to customer on active maintenance, your company will need to renew support subscription if you expect support and patches. We implemented QuickRouter 6-7 years ago specifically for you guys (documented in this thread), but we can't really afford providing you with free support forever after Smiley

Makes sense Smiley due to internal miscommunication, I have trouble knowing what our agreement is or was...

Thanks,

Théo

Last questions:
- in which version has this been fixed ? We're using 5.6.1, but I've been told we had v5.6.3 somewhere.
- If that's not enough, are you willing to give us any hint to fix it ourselves ? Sadly, I think I won't be able to convince people to spend money...we're too busy giving it to "this big company holding the 3d modeling/animation monopoly" -_-

Thanks

I think it was fixed in v6.0.4. Support and upgrades for one developer would cost you something like $250 for an year. But ok, if you are in such bad situation we will give you latest comparer code as one-time service, you can find it on private messages page.

I hope that helps,
Stoyan
