Can't create links with new Flowchart 5.3

Hi Stoyan,

I was trying to use the new Flowchart version to be able to use your great ( 8)) functionalities, but it introduces a bug.

I can't create links anymore. Just to remind you, I have only table nodes. They each have 2 columns with anchor points on the table node's borders 1 for each cell. When a link has been created (i.e. in diagram.LinkCreated), e.link.DestinationIndex is -1. It used to be the row's index. I can't get the information I need anymore... Do you have any idea why it does this? It didn't do it before I switch for the new Flowchart version and I didn't change anything... My old Flowchart version was a custom version that comes from somewhere in March (5.2.0.23855).

Thanks,
Marie

Hi Marie,

I have added a LinkCreated handler to the Entities example, it works fine:

Code
Select All
private void diagram_LinkCreated(object sender, LinkEventArgs e)
{
	Debug.WriteLine(e.Link.OriginIndex);
	Debug.WriteLine(e.Link.DestinationIndex);
}


If you set your tables Scrollable and scroll the rows up or down, do the links move with them? If they stay where they were initially connected, that means they are not connected to a distinct row for some reason, but to the table as a node.

Hi Stoyan,

Sorry for the late answer... It went out of my mind...

However, I now need to fix this problem as soon as possible Tongue.

I was mistaken. It is not the DestinationIndex that was -1 (it is fine), but the DestinationAnchor. The origin is as it was.

I was wondering if you had any idea why the DestinationAnchor is not set anymore in LinkCreated with the new version? It was working before but not anymore and nothing was changed (except for the Flowchart dlls).

I tried looking in my (huge) code to find if I did anything that could interfere but I didn't find anything, especially knowning that it used to work fine and that it is set automatically by your code. Do you have an idea of what could cause that (either from my side or yours)?

If I create nodes programatically, everything is fine. As you mentionned, the links stay connected even if I scroll. I can't test the scrolling with new UI links since I can't create links at all that way.

Thanks again for your help,
Marie

p.s. Another guy from my work will take over my task. He might be the one to answer future posts.

Hi,

Please email to support@mindfusion.eu a test project that shows the problem.

Hi Stoyan,

I work with Marie and I've been assigned the bug.

Unfortunately, I don't have a simple test program for you to repro the problem and I can't send you the problematic part of our projet since it's too big and confidential. But I can save the graph has an xml if it would help.

So, to resume the problem, inside LinkCreated, with 5.2.0, DestinationAnchor is set to the right value but when I switch to version 5.3.2, DestinationAnchor is always -1. Was there any changes in the way DestinationAnchor are set in LinkCreated between version 5.2.0 and 5.3.2 ?

Thanks,
JC

It would be best if you copy the relevant code from the LinkCreating, LinkCreated and ValidateAnchorPoint handler from your main project to a test project to isolate the problem, and email it to us.

Hi Stoyan,

I ran a debug version of your libraries and while stepping through it I found the problem.

When the CompleteCreate function in DiagramLink is called, the variable routedWhileCreating is set to true because we have autoRoute to true. Doing so, the true branch of the if (routedWhileCreating) is taken and that path doesn't contain code to set the DestinationAnchor. But, the DestinationAnchor is set if routedWhileCreating is false and my links are creating as expected.

So my question is, is it up to me to set the DestinationAnchor if I have the autoRoute on ?

Thanks,
JC

Hi JC,

In this case it should depend on RoutingOptions.Anchoring. Are you using a value different than Ignore? If it is different, but the link still doesn't connect to anchor points, I suppose we might have forgotten checking that value in the new router we implemented for you.

Hi Stoyan,

The RoutingOptions.Anchoring is set to Keep and RoutingOptions.IgnoreAnchoring is set to false.

I'll try setting the autoRoute to false to see what it does to the look & feel of the application while I wait for a confirmation if it's a bug or not.

Thanks,
JC

Hi JC,

This version should set the link anchor properties as expected when using the WhileCreating option:

I hope that helps,

Hi Stoyan,

I can confirm that it does work using this version without any modification to our code.

Thanks,
JC

Hi Stoyan,

Would it be possible to get the source code and an installer for this new 5.3.3 beta version ?

Thanks,

Hi JC,

For the source code check the PM page. We'll build v5.3.3 installers next week.
