But still can't figure out why the error is happening on calling diagram.saveToString


Are you still getting same error after renaming your style() function, or just wondering why it was happening before that? If you have a custom link.style() method in your links, it will confuse our writeStyle method called when saving to XML, because it looks for some appearance attributes in link.style objects.

Well, it is definitely an error is in instantiating custom diagram link, since custom class has no properties or style function in it, only inheritance  and that method overrid (DrawLinksBehavior.prototype.createLink = function (origin, point) ), so it seems, i need to specify some parameters or god know what. Is there a way to figure out that?
What this error means "Key type not supported." ?

And the source of it was this thing:

this liner in custom diagram link (backend) is causing an issue:

this.Shape = LinkShape.Cascading;

is it something wrong with that liner?

an error:
An exception of type 'System.Reflection.TargetInvocationException' occurred in MindFusion.Diagramming.DLL but was not handled in user code

Hi. I noticed a problem - diagram.saveToString(MindFusion.Diagramming.SaveToStringFormat.Xml) does not save <GridPointSize>1</GridPointSize> node. Before calling this method, I have checked that diagram.getGridPointSize() returns valid value.

Hi,

This build adds it to both JSON and XML serializers -
https://mindfusion.eu/_beta/jsdiag_gridpointsize.zip

Hi. Thanks! Well, I faced another problem with diagram xml saving. After saving, <GridColor> node has value #00000000. After loading this diagram grid disappears. I edited xml and changed <GridColor> value to #1B000000 (also black) and grid became visible.

I tried it with other colors and made the conclusion, that if first two digits is 00, after loading xml, then grid is not visible.

Maybe there are some problems with saving or processing AARRGGBB color codes?

As I understand, the problem is, that color should not be saved with two leading zeros, it makes grid transparent

Another problem with .saveToString() is that it doesn not save <AdjustmentHandlesSize>8</AdjustmentHandlesSize> node (inside <Properties> node)

Without it, adjusment handles is not visible

Seeing that #1B000000 value, do you work on same project as Vitaly here ?
http://mindfusion.eu/Forum/YaBB.pl?num=1487930193

You will have to use the new assemblies from zip file from end of that thread, they implement some fixes for saving colors with semi-transparency. If you don't use ASP.NET version but stand-alone JavaScript library, make sure you replace the common.js file with one from jsdiag_gridpointsize.zip. If that does not work, please let me know the original color value string you are assigning to GridColor.

Regards,
Slavcho

Updating dlls solved problem with grid color, but not solved problem with adjustment handles.
