Hi,

So it could be an unconnected link. E.g. if you call diagram.setAllowUnconnectedLinks(true) users will be able to draw links without connecting them to nodes. If you are creating links from code, e.g. by parsing some data files, make sure you have set both Origin and Destination link's nodes.

I can't see that happening when I add this to Containers.js example -

Code
Select All
var link = diagram.getFactory().createDiagramLink(ctr[0], ctr[1]);
link.setSegmentCount(3);
link.setShape(MindFusion.Diagramming.LinkShape.Cascading); 



Let me know what I should change there to reproduce.

Regards,
Slavcho

i am using below property for line,
link.setStrokeDashStyle(MindFusion.Drawing.DashStyle.Solid);
link.setLineAlignment(MindFusion.Diagramming.Alignment.Far);
link.setStrokeThickness(1);
let style = new MindFusion.Diagramming.Style();
style.setBrush(StringHelper.blackColor);
link.setStroke(StringHelper.blackColor);
link.setBrush(StringHelper.blackColor);
link.setHeadStrokeThickness(1);
link.setHeadShapeSize(2);
link.setHeadBrush(StringHelper.blackColor);
link.setHeadStroke(StringHelper.blackColor);


and one more thing i am using elbow connector lines may that's why this happen.

link.setHeadShapeSize(2);
link.setHeadBrush(StringHelper.blackColor);
link.setHeadStroke(StringHelper.blackColor);
 



in Containers.js still does not reproduce, and these properties only affect rendering code anyway. If your app's not setting any other link -related properties, maybe check event handlers like nodeModified / nodeModifying.

I checked in nodemodify event on that nothing is code

i observerd that there is origin and destination for link as well as on node outgoing link avaliable.

when i move that node automatically this link is also moved but showing pointing location different,it is  disconnected.

If the link moves with the node, check if there aren't anchor point coordinates larger than 100 assigned to the node (they are specified as percentage). If using any custom drawing code or custom template, make sure your graphics do fill all of node's Bounds.

If you are programmatically assigning new coordinates to the link's ControlPoints list, you should also call link.updateFromPoints in the end. That updates an internal relative-position field, which is used to determine end point positions later when nodes move or resize.

I have attached two attachment
1)Node_Link_Control_Points:This contain selected node link control points
2)Selected_Link_control_points:This contain selected link control points

In above node and link disconnected but showing incoming link and origini data

While comparing i observed only this difference .
Please suggest me what i can do?

I'm not sure what these screenshots are supposed to show. If they were taken without moving anything but only selecting objects and checking coordinates in debugger, I guess it could mean the node's link is an invisible one, and the clicked link is different that what you expect.

Does that link appear as disconnected only after you move a node, or when you see it initially? If it appears disconnected from the beginning, please post the code that creates it. If disconnecting only when moving, it's probably this -

yes i have used the same updatecontrolpoints but still not fixed this issue.
when i play with node for eg. i am moving node continuously both node origin as well as destination then this issue is reproduced

link only disconnected when i am moving node that is only scenario

Moving the link along with both its origin and destination selected works in my test. Please try editing attached code with your settings until it starts reproducing and send us the result.

Can you please try with this scenario just move node with cursor do not put node on modified just moving to node and at last just put that node on one place and change position of another connected node and check link is disconnected

something like this?

- click container 1
- move container 1 down
- click container 2
- move container 2 up
- click container 1
- move container 1 up
- click container 2
- move container 2 down

works in my test attached to post above. Have you tried that in the container.js sample or only in your project? If containers.js not working on your end, what browser are you using and does it show any errors in console? Are you using latest version of the diagram in your project?
