saveToString throws Cannot read properties of undefined (reading 'toString')

Hi there,

When I am trying to save data in serialized string format in JSON format like this:

Code (Javascript)
Select All
var stringDiagramData = diagram.saveToString(MindFusion.Diagramming.SaveToStringFormat.Json);


then it works great.

But if I chose XML format like this :

Code (Javascript)
Select All
var stringDiagramData = diagram.saveToString(MindFusion.Diagramming.SaveToStringFormat.Xml);

then it throws me following error:
VM254:1 Uncaught TypeError: Cannot read properties of undefined (reading 'toString')

Perfect it works thanks!

Also I have one more concern? When I am trying to drag item they are not in sync therefore it is difficult to drag items, as shown in the attached pics.


Also when I hover mouse over the diagram node or path, they are out of sync, you can see in attached pic the resize arrow is out of sync.

Thanks

Are those custom mouse cursors, or some magnification effect of your screenshot app? If using custom cursors, make sure you haven't assigned wrong images. Otherwise please attach a minimal sample reproducing that.
