XML.Load timeout in flash lite 2.x

[captain_planet]

Hi.

I'm using XML to display a latest news feed on my mobile app. I use the example here:
http://wiki.forum.nokia.com/index.ph...arse_XML_files

Everything works great, but if (for example) my web server is not responding (say the web server is down) the xml.load must poll the web server for about 20 seconds or more trying to connect, delaying my app from loading. I'd like it to try to load the xml file for 5 seconds and if it doesnt get a response from the web server then carry on loading the app.

I've looked into adding a timeout using these methods:
http://www.gskinner.com/blog/archive...timate_as.html
and Loadvars onHTTPStatus

but none are supported in flash lite 2.x. Can anybody suggest another approach please?
Thanks for any help.

You can simply create a setInterval for 5 seconds, after you attempt to load the external XML.
When the timer event fires, check if XML.data = null, if so you can conclude that webserver is down.

Ahhh, ok. Interesting. Thanks. I've just knocked this code up, but can't test it right now. I hope it's what you mean, and I'll see if it works later:

stop();

// create a new XML object
var myPhoneXML = new XML(); 
//Text nodes that contain only white space are discarded
myPhoneXML.ignoreWhite = true; // define the onload handler
myPhoneXML.onLoad = function(success) 
{	
if (success) {		
	//do something
} else {		
	//do something else
}}; 

// load the XML file into the myPhoneXML object
myPhoneXML.load("http://www.website.com/whatever.xml");

setInterval(
myPhoneXML.onData = function(src){
	if (src == undefined) {
		this.onLoad(false);
		//did not load ok
	} else {
		this.parseXML(src);
		this.loaded = true;
		this.onLoad(true);
		//loaded ok - call onload
	}
}
,5000);

Not exactly.
Don't put any onData handler in the interval function. Just check the property.
onData handler is invoked when the XML is completely loaded.

[captain_planet]

Which property are you both referring to? If i try:

setInterval(
function(){
if (xml.data == null) {
trace("null")
}else
{
trace("not null")
}
}, 1000 );

i get "There is no property with the name 'data'"??

[captain_planet]

hmmm....i have a feeling that you guys are talking about using shared objects......

[captain_planet]

OK, i guess effectively i could just use a couple of booleans as opposed to checking the data of a shared object like below, right? I think it would work in principle. But this brings me on to my next question.

xml.load gets called.
A prompt appears on the mobile saying "Connect to network?" or similar

Is there any way to wait for a user selection here? Because using setInterval like below just carries on after 5 seconds even if the user hasn't made a selection?

Thanks.

stop();

var blnLoaded : blnLoaded = false;

// create a new XML object
var myPhoneXML = new XML(); 
//Text nodes that contain only white space are discarded
myPhoneXML.ignoreWhite = true; // define the onload handler
myPhoneXML.onLoad = function(success) 
{	
if (success) {		
	blnLoaded = true;
} else {		
	blnLoaded = false;

}}; 
// load the XML file into the myPhoneXML object
myPhoneXML.load("http://www.website.com/whatever.xml");

setInterval(
function(){
if blnLoaded == false
{
    //continue instead of waiting
}
}
,5000);

I'm wondering if setting the 'script time limit' to 5 seconds under Publish Settings would be better than using SetInterval.....anybody used this? Thanks...

Please set a variable parameter after url... So, you can get updated data.

Even you can also use YQL to easy load query data.
