addCell(Link)

[che]

Hi there,

I draw many elements using "jsonObject = graph.toJSON();" this line.

Then I saved jsonObject in Mongo and load it on graph but only link is not presenting.

Here is the jsonObject.

And I used following code to draw link.

````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````

elements.cells.forEach(element => {

            if(element['type'] == "link") {

                graph.addCell(element);

            }

        });

````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````

I thought problem was target and source elements is existing yet. So, I draw other rec and custom elements first and draw link later but end up with this error message.

 

Do you know what does this message mean?

Many thanks!

It means that the source or target of a link does not exist in the graph.

link.set('target', { id: 'non-existing-element-id' }); would throw the same error.
