Just upgraded from 6.0.0 to 6.0.4..

When a placing a node into a container, then collapsing the container, the connections to the node inside of the container float below the container..

Cannot reproduce that in the Demo -> Containers step. What properties should we set to see the problem?

Nevermind, ran the installer and found it. Will try to reproduce the issue in the demo app.

Nevermind. It was something in our code and not yours.

I was able to crash the Demo app..

Open the Demo application, and go to the Links/Form preservation example.

Create a container.

Place the three purple tools in the middle inside of the container, and then collapse it.

Now move the collapse container around.

The links will draw all over the place before the overview window gets a red X and the following exception is thrown:

Code
Select All
System.OverflowException: Overflow error.

It seems the combination of links' Dynamic + RetainForm properties does not work that well when the link target nodes are inside a folded container. If you need to use RetainForm, you could toggle link.Dynamic off or on from respectively ContainerFolded / ContainerUnfolded event handlers as a work-around. Our developer will try to fix that in next few days.

I hope that helps,
Stoyan
