Question

When I make a quick wsapidatastore for user story, it works:

Ext.create('Rally.data.WsapiDataStore', {
            model: 'User Story',
            autoLoad: true,
            listeners: {
                load: this._onArtifactsLoaded,
                scope: this
            }
        });

But if I change it to Artifact, I get an error:

Ext.create('Rally.data.WsapiDataStore', {
            model: 'Artifact',
            autoLoad: true,
            listeners: {
                load: this._onArtifactsLoaded,
                scope: this
            }
        });

Console says:

Uncaught TypeError: Cannot call method 'replace' of undefined sdk-debug.js:104071
Ext.define._buildTypeInfo sdk-debug.js:104071

It looks like there is a error in the model factory.

If you need a workaround you can use this line of code to add artifact as a legit type.

Rally.data.ModelTypes.types.artifact = 'artifact';
