copySelection exception when the selection contains links

[aspirio187]

Hi,

After using e.diagram.commandHandler.selectAll(), which will select links and nodes, if you try to use the function e.diagram.commandHandler.copySelection(). The app will crash and display this error:

Cannot read properties of null (reading 'iteratorValues')
TypeError: Cannot read properties of null (reading 'iteratorValues')

I tried to only select nodes and copy, it does work. It is however, possible to select all and remove.

I am using GoJS with ReactJs.

The parameters allowCopy, allowDelete and allowLink are all set to true during diagram initialization.

// set your license key here before creating the diagram: go.Diagram.licenseKey = "...";
const diagram = new go.Diagram({
  allowCopy: true,
  allowDelete: true,
  allowLink: true,
  initialAutoScale: go.AutoScale.UniformToFill,
  ...
})

Thanks for reporting this. What version of GoJS are you using?

[simonsarris]

We've been able to reproduce this. A fix will be out with the next version, released probably some time in the coming week.

This has been fixed in 3.0.2, which we just released. Thank you for reporting it.
