How to show task revisions in custom grid?

Question

I have a custom grid that displays open tasks filtered by (Owner = [email protected]).

I would like to include the last revision for each task in a custom grid, but the Revision column is not available on the settings dialog. How to traverse from Revision History to individual revisions?

Answer 1

It can't be done with a custom grid, but can be done with a custom code. Here is an app example that populates a grid based on a selection in the UserSearchComboBox , and then displays the last revision of a selected task on a click event.

You may copy the html file into a custom page from this github repo:

Here is the js file:

Ext.define('CustomApp', {
    extend: 'Rally.app.App',
    componentCls: 'app',

        launch: function() {
        var context  = this.getContext (); 
        var currentProject = context.getProject()._ref;
        var panel = Ext.create('Ext.panel.Panel', {
                layout: 'hbox',
                itemId: 'parentPanel',
                componentCls: 'panel',
                items: [
            {
                    xtype: 'rallyusersearchcombobox',
                    fieldLabel: 'SELECT USER:',
            project: currentProject,
                        listeners:{
                            ready: function(combobox){
                                this._onUserSelected(combobox.getRecord());
                           },
                           select: function(combobox){
                if (this.down('#c').html !== 'No task is selected') {
                Ext.getCmp('c').update('No task is selected');
                }
                                this._onUserSelected(combobox.getRecord());
                           },
                            scope: this
                        }
                    },
            {
