Hi Mike
I have an application file as suggested. I modified the js content to load the html content dynamically, and also refering the swf by the relative path for the presto artifacts lying within the file system.
The application fails to lod in Internet Explorer, (have verified it on IE version 6,7 and 8), but it works fine in mozilla and chrome.
In IE i end up getting the error message in the browser
"Failed to load app - could not locate the jsclass - NotificationAuditLog.JS"
Please find attached the app.zip file
Thanks in advance
I think you need to simply add a "loadconfirmation" on your <require> element for js/app.js:
Currently in your App.xml, you have:
Hi
I modified the file as per your suggestion, but still I guess it fails after proceeding partially. Now I get to see a "Loading" banner on top of the browser, followed by the same error message Failed to load app - could not locate the jsclass - NotificationAuditLog.JS.
Earlier it did not show the "Loading" banner on the top, but with the change as suggested, I could only see only this being appended on the top of the eror message, the application still fails to launch. 
Attached the image for your reference.
This is occurring because of an error in your js/app.js file that only breaks in Internet Explorer. For some reason, IE will break (but FF, Chrome and Safari won't) if your javascript contains unnecessary commas. See:
http://www.enterprisedojo.com/2010/12/19/beware-the-trailing-comma-of-death/
for a full explanation.
After I fixed your app.js file the app loaded fine on my system (although it didn't do anything because I don't have the backend NotificationAuditLogMashup that your app calls).
You needed to remove the trailing comma of death on line 65. You should also consider running your code through jslint.
Hi
We have created a custom application which loads an html component and uses it in the presto application.
We have added the js code for loading the same, it works fine in Mozilla and Chrome but fails to load in the IE, it gives an error "Failed to load app - could not locate the jsclass"
Please suggest if we need to add any pluggin, or can we handle it in our code to make this app work in all the browsers
Below is the attached sample form the JS class
NotificationAlert = function(app) {
this.app = app;
instance = this;
var intvl = setInterval(function() {
if (document["AlertsView"] && document["AlertsView"].renderAlertsInTable) {
clearInterval(intvl);
instance.receive();
}
}, 100);
};
NotificationAlert.prototype = {
// *receive method* , this method is called when a publisher sends data to this suscriber
// configured manually in mashboard
receive: function() {
//console.log("receive",data)
var conn = this.app.getConnection(), app = this.app;
jQuery(app.rootElement).find(".waiting").show();
conn.request({
sid: 'Event_Notification_Mashup',
oid: 'runMashup',
header: {
resultFormat: 'xml'
},
},
{
onSuccess: function(response) {
jQuery(app.rootElement).find(".waiting").hide();
var intvl = setInterval(function() {
if (document["AlertsView"] && document["AlertsView"].renderAlertsInTable) {
clearInterval(intvl);
document["AlertsView"].renderAlertsInTable(response.response);
}
}, 100);
},
onFailure: function(err) {
console.log("Service Error:", err);
},
scope: this
});
}
