Remove all TestCases associated to a TestSet - extjs

Question

With Rally SDK 2.0 APIs, I want to associate new TestCases to a given TestSet. To do this I :
initialize a store:
me.selectedTestCasesStore = myTestSet.getCollection('TestCases',{...});
Remove all items (I don't want to keep them):
me.selectedTestCasesStore.removeAll();
Add the new TestCases
me.selectedTestCasesStore.add({'_ref':aTestCaseRecord.data._ref});
Then synchronize
me.selectedTestCasesStore.sync({...});
Step 1 is OK : console.log(me.selectedTestCasesStore) shows me the collection in data.items[].
Step 2 seems OK as a console.log(me.selectedTestCasesStore) shows me nothing in data.items[] (previous records are gone).
Step 3 is OK because added test cases which were not present at step 1 are now in the collection
Step 4 : Called function is "success"
BUT... only new TestCases are added, the old ones are not removed, as if step 2 has no effect. What's wrong in my code ? I extract the part of the concerned code :
// me.selectedTestCasesStore : my store, with old TestCase associated to a TestSet.
// It is initialized with something like :
// me.selectedTestCasesStore = myTestSet.getCollection('TestCases',{...});
//
// selectedTestCasesArray : an array of records with the new TestCases to assign to the test set.
_removeAllFromSelectedTestCaseStore:function()
{
var me = this ;
console.log('In _removeAllFromSelectedTestCaseStore');
me.selectedTestCasesStore.addListener({
clear : me._addSelectedTestCasesToSelectedTestCaseStore,
scope : me,
});
// Remove all associated TestCases from selectedTestCases store
me.selectedTestCasesStore.removeAll();
},
_addSelectedTestCasesToSelectedTestCaseStore:function()
{
var me = this ;
console.log('In _addSelectedTestCasesToSelectedTestCaseStore');
console.log(' After remove, store is now :',me.selectedTestCasesStore);
// Add each check TestCase to selectedTestCases store
for (var i=0; i < me.selectedTestCasesArray.length; i++)
{
// Add it to the collection
me.selectedTestCasesStore.add({'_ref':me.selectedTestCasesArray[j].data._ref});
}
console.log(' After add, store is now :',me.selectedTestCasesStore);
// Synchronyze
me.selectedTestCasesStore.sync(
{
success: function(batch, options) {
//success!
console.log(' Success', me.selectedTestSetStore);
},
failure: function(batch, options){
console.log(' Faillure :(', me.selectedTestSetStore);
},
});
},
Thanks for your help !

This works for me instead of removeAll():
var testcases = testCaseStore.getRange();
_.each(testcases, function(testcase) {
testCaseStore.remove(testcase);
});
Here is the full js file that empties the test case collection on a test set before adding a new test case
Ext.define('CustomApp', {
extend: 'Rally.app.App',
componentCls: 'app',
launch: function() {
console.log("launch");
Rally.data.ModelFactory.getModel({
type: 'TestSet',
success: this._onModelRetrieved,
scope: this
});
},
_onModelRetrieved: function(model) {
console.log("_onModelRetrieved");
this.model = model;
this._readRecord(model);
},
_readRecord: function(model) {
var id = 16805375409;
console.log("_readRecord");
this.model.load(id, {
fetch: ['Name', 'FormattedID', 'TestCases'],
callback: this._onRecordRead,
scope: this
});
},
_onRecordRead: function(record, operation) {
console.log('name:', record.get('Name'));
console.log('test cases:', record.get('TestCases'));
if(operation.wasSuccessful()) {
var testCaseStore = record.getCollection('TestCases', {
autoLoad: true,
listeners: { load: function() {
var testcases = testCaseStore.getRange();
_.each(testcases, function(testcase) {
testCaseStore.remove(testcase);
});
testCaseStore.sync({
callback: function() {
console.log('test cases after removeAll():', record.get('TestCases'));
}
});
testCaseStore.add({'_ref':'/testcase/14469886070'});
testCaseStore.sync({
callback: function() {
console.log('test cases after add():', record.get('TestCases'));
}
});
}}
});
}
},
});
