get model data after change event

[tommybernaciak]

Is this possible to get model data after the diagram is changed? What I try to do is handle onModelChange event for ReactDiagram component. It returns data of go.IncrementalData type which should return me modelData but I never receive it. I receive all other properties like insertedNodeKeys, modifiedNodeData etc. I could build up an updated model using those data but I assume that model should be already available using modelData property, am I right?

The IncrementalData will include a "modelData" property only if the Model.modelData shared object had been modified. https://gojs.net/latest/api/symbols/Model.html#modelData
