RussianPlease take a look at the code in this post, where Mark uses promises, and builds three separate Rally.data.wsapi.Stores and only after all the data is there _makeGrid(resultArray) is called.
Loading grid only after "all" the data stores have loaded
Question
I have this code that loads a data store for all stories that contain each of the names from an array.
var prefix_set = [list of names]
for(var i=0;i<prefix_set.length;i++)
_get_stories_of_feature(prefix_set[i]) //this function creates a data store
I am storing all the data into a global array and creating a data store which is passed to a grid in the end. The problem is that my grid loads up with incomplete data (the grid loads up even before all the data has been loaded into the global array).
Here's my code:
Ext.define('CustomApp', {
extend: 'Rally.app.App',
componentCls: 'app',
items:[{ xtype: 'container', itemId: 'print_button_box', padding: 5},{xtype: 'container', itemId: 'grid_box'}],
count: 0,
globalStore: null,
totalDataLength: 0,
gridCounter: 0,
launch: function() {
var me = this;
this.globalStore = null;
this.gridCounter = 0;
this.totalDataLength=0;
this.count = 0;
this._addPrintButton();
list = [];
//Write app code here
var prefix_set = ["Epic:","Arch:","Refa:","Innov:","Spike:","Producer:","Dependency:","Consumer:"];
var i;
for(i=0;i<prefix_set.length;i++){
this._get_stories_of_feature(prefix_set[i],prefix_set.length,i);
}
},
_addPrintButton: function() {
var me = this;
this.down('#print_button_box').add( {
xtype: 'rallybutton',
itemId: 'print_button',
text: 'CSV',
disabled: false,
handler: function() {
console.log('globalStore ',me.globalStore);
me.exportGrid(me.globalStore);
}
});
},
_onClickExport: function () {
if (document.getElementById('grid_box')) {
//Ext.getBody().mask('Exporting Tasks...');
console.log('inside export');
setTimeout(function () {
var template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-' +
