I have a rally.sdk.ui.basic.Dropdown menu in a Rally App that I would like to change based on user input. So I will call display() on the dropdown menu, and then later I want to change the contents of that menu.
Has anybody done this? When I try, it crashes. I’ve also tried calling destroy() on the dropdown menu and then calling display() on a new menu that I allocate, but that crashes as well with an obscure dojo error.
Any suggestions on how to change dropdown menus on the fly?
I’ve included a very stripped down example below of trying to destroy and then re-display the menu:
<html>
<head>
<title>Incoming Defects by Severity</title>
<meta http-equiv="X-UA-Compatible" content="IE=7" >
<meta name="Name" content="Defects by Severity" />
<script type="text/javascript" src="https://rally1.rallydev.com/apps/1.29/sdk.js"></script>
<script type="text/javascript">
function DefectChart() {
this.display = function() {
var defectVersionDropdown;
var count = 1;
function makeDefectChart(results){
initDefectVersionDropdown();
};
function renderPage() {
var queryConfig = [];
var startDate = '2011-06-06';
var endDate = '2012-02-02';
var queryArray = ['CreatedDate >= "' + startDate + '"', 'CreatedDate <= "' + endDate + '"'];
var versionFilter = defectVersionDropdown ? defectVersionDropdown.getDisplayedValue() : 'ALL';
if (versionFilter != 'ALL') {
queryArray.push('FoundInBuild contains "' + versionFilter + '"');
}
// console.log(queryArray);
queryConfig.push({
type : 'Defects',
key : 'defects',
query: rally.sdk.util.Query.and(queryArray),
fetch: 'Severity,State,LastUpdateDate,CreationDate,OpenedDate,AcceptedDate,LastUpdateDate,ClosedDate,Environment,FoundInBuild'
});
rallyDataSource.findAll(queryConfig, makeDefectChart);
}
function defectVersionChange(sender, eventArgs) {
var version = eventArgs.value;
renderPage();
}
function initDefectVersionDropdown() {
if (defectVersionDropdown != null) {
defectVersionDropdown.destroy();
defectVersionDropdown = null;
}
if (defectVersionDropdown == null) {
console.log('initDefectVersionDropdown');
count++;
var menuItems = [{label: "ALL", value: "ALL"}];
for (var i=0; i < count; i++) {
menuItems.push({label: count, value: count});
}
var config = {
label: "Found In Version:",
items: menuItems
};
defectVersionDropdown = new rally.sdk.ui.basic.Dropdown(config);
defectVersionDropdown.addEventListener("onChange", defectVersionChange);
defectVersionDropdown.display("defectVersionDiv");
}
}
var workspaceOid = '__WORKSPACE_OID__'; if (workspaceOid.toString().match(/__/)) { workspaceOid = XXX; }
var projectOid = '__PROJECT_OID__'; if (projectOid.toString().match(/__/)) { projectOid = XXX; }
rallyDataSource = new rally.sdk.data.RallyDataSource( workspaceOid,
projectOid,
'__PROJECT_SCOPING_UP__',
'__PROJECT_SCOPING_DOWN__');
initDefectVersionDropdown();
renderPage();
}
}
function getDataAndShow() {
var defectChart = new DefectChart();
defectChart.display();
}
function loadRally() {
rally.addOnLoad(getDataAndShow);
}
loadRally();
</script>
</head>
<body>
<div id="defectVersionDiv"></div>
</body>
</html>
Destroying the old one creating and displaying a new one is the correct way to do this. This is a common pattern when developing apps using the App SDK. If you provide a code snipped along with the dojo error you are getting the community can probably be of better assistance.
