How to query for all Artifacts of a Milestone - rally

Question

I am attempting to create reports on Milestones using App SDK 2.0 and would like to find all User Stories that have been assigned to the Milestone.
I tried pulling out the Artifacts from a Milestone using getCollection.
Ext.create('Rally.data.wsapi.Store', {
model : 'Milestone',
filters : [ {
property : 'ObjectID',
operator : '=',
value : milestone.get("ObjectID")
} ],
fetch : [ 'Artifacts' ],
limit : Infinity,
autoLoad : true,
listeners : {
load : function(store, records) {
var record = records[0];
var info = record.get('Artifacts');
var count = info.Count;
record.getCollection('Artifacts').load({
fetch : [ 'ObjectID' ],
callback : function(records, operation, success) {
Ext.Array.each(records, function(artifact) {
console.log(artifact.get('ObjectID'));
});
}
});
}
}
});
I get the following error:
Uncaught Rally.data.ModelFactory.getModel(): Could not find registered
factory for type: Artifact sdk-debug.js:7078
From https://rally1.rallydev.com/slm/doc/webservice/, it doesn't seem that Milestones is query able on the User Story or PortfolioItem. I tried it anyway using Tasks syntax and it nothing was returned.
Ext.create('Rally.data.wsapi.Store', {
model : 'UserStory',
filters : [ {
property : 'Milestones',
operator : 'contains',
value : milestone.get("_ref")
} ],
fetch : [ 'ObjectID' ],
limit : Infinity,
autoLoad : true,
listeners : {
load : function(store, records) {
console.log(records);
}
}
});

There is a defect in AppSDK2 that it does not work with abstract types, e.g. Artifact, UserPermissions.
Your first code example ran into that defect.
But your second code example must work. I suspect if it does not work for you it is a matter of scoping. Perhaps the milestone you filter by is not in the project you are scoped to. You may hard code a project ref in the context of the store to make sure it is looking in the right project. I initially tested your code in my default project and it worked as is, and then I modified it as follows to make sure it finds a milestone in a non-default project:
Ext.define('CustomApp', {
extend: 'Rally.app.App',
componentCls: 'app',
launch: function() {
Ext.create('Rally.data.wsapi.Store', {
model : 'UserStory',
context:{
project: '/project/16662089077'
},
filters : [
{
property : 'Milestones',
operator : 'contains',
value : "/milestone/33215216897"
}
],
fetch : [ 'ObjectID' ],
limit : Infinity,
autoLoad : true,
listeners : {
load : function(store, records) {
console.log(records);
}
}
});
}
});
