FlowLayout.Arrange method hangs

Hi there

I'm having a problem with the FlowLayout.Arrange method, it seems to hang in some scenarios.

This issue can be easily recreated using the ProcessLayout example:

    Press Arrange button to put nodes in lanes.
    Delete link from ‘Client Credit OK?’ node to ‘Process task’ node.
    Create link from ‘Accept task’ node to ‘Process task’ node by dragging from ‘Accept task’ node to ‘Process task’ node.
    Press Arrange button to put nodes in lanes.
    Execution hangs on the ‘FlowLayout.Arrange(diagram)’ line of the arrangeButton_Click sub in Mainform.

Is this a bug or am I doing something stupid (very possible..)

Thanks

Tom

Right, that's a bug in our code. Our developer will fix it in the next few days and we'll send you an updated version.

Hi,

This version should fix the problem:
https://mindfusion.eu/_temp/flowlt.zip

It also lets you left-align the groups. To do so, add this code:
rules.NodeRules.VerticalDisconnectedGroupsAlignment = true;

For the next official release we'll probably change the property type to some enum to allow for more types of alignments.

I hope that helps,
Stoyan
