Cancel edit dialog removing shape and dataItem

[Ralph]

Hello, 

I have come across an issue where shapes are being removed from the diagram when I choose to cancel the edit dialog. The issue seems to be tied to the schema of the dataSource. If I provide a mapping for the 'id' of elements in the dataSource using the cancel button on the edit dialog causes the shape and element to be removed: http://dojo.telerik.com/osOmA/7 

If this mapping is removed then the shapes function as expected.

Thanks

Hello Ralph,

You should change the id field to "id" to avoid the problem:

schema: {
    model: {
      id: "id",
      fields: {
        id: { from: "Id", type: "number", editable: false },
        Text: { type: "string" }
      }
    }
}

The from option basically replaces the original field so "Id" will no longer be defined.

Hi,

Thank you for the response, which does work around the problem. However, could you please enlighten me as to what the point of the mapping is in this case then? It seems like anything other than the following configuration seems to break the diagram. Even leaving this mapping off causes the diagram to break. 
model: {
  id: "id",
  fields: {
     ...
  }
}

Thanks

Hello again,

I am not sure if I understand the issue. What other configurations have you tried? 
Mapping the id field is not absolutely necessary. It will be done automatically by the model when setting the id option so you could use either:

model: {
  id: "id",
  fields: {
    id: { from: "Id", type: "number", editable: false },
    Text: { type: "string" }
  }
}

or:

model: {
    id: "Id",
    fields: {
        Id: { type: "number", editable: false },
        Text: { type: "string" }
    }
}

in the specific scenario.
