Link from/to value type in 3.0

GoJS
1

Hi,

When i used GOJS 2.3, i used to have the link from/to as strings, for example : “from” : “44545”

Now i see that i have to treat them as integers, namely change all my JSON files to from/to : int

Any work around

Strings should work just fine, as long as your data is consistent, and you are using strings everywhere, for example this will work:

  myDiagram.model = new go.GraphLinksModel(
    [
      { key: '1', text: 'Alpha', color: 'lightblue' },
      { key: '2', text: 'Beta', color: 'orange' },
      { key: '3', text: 'Gamma', color: 'lightgreen' },
      { key: '4', text: 'Delta', color: 'pink' }
    ],
    [
      { from: '1', to: '2' },
      { from: '1', to: '3' },
      { from: '2', to: '2' },
      { from: '3', to: '4' },
      { from: '4', to: '1' }
    ]
  );

But if the Node keys are numbers, and the from/to are strings, you will have trouble.

Strange,

cause in GOJS 2.3 i was able to mix string and int, as keys

In 3.0, I had to replace all the from/to to int cause the node key is int

We changed our backing data structures to use the built-in JS Map and Set (originally released in 2015, now widely available), the built-in JS map treats "1" and 1 as different keys, while our Map (created in 2010) did not. We mention this issue in the Changelog as a potentially incompatible 3.0 change:
