_17 = null;

if (o.conn && o.conn.readyState == 4)
At unknown location

[statement source code not available]

the response was

<response type="success">

where is the problem?
in FF2 i got no probs with this, maybe my ext-version is to old? i am using ext.1.0.1a

Use ext-all-debug.js so you can step thru the code. Did you set the right content-type for your response (multiple threads re this)?

14 Jun 2007, 10:29 AM
the contenttype is text/xml...

its in Ext.util.JSON the function is

this.decode = function(json){

return eval("(" + json + ')');

whats the problem in parsing an xml response? every post request to the server fails in opera
get-requests are working fine

please somebody gimme a hint :)

If you're reading XML, why is it going thru the JSON eval process? Or are you calling that function manually. Xml is returned as an Xml document, not a string.

15 Jun 2007, 5:57 AM
i think its a string, which is a valid xml, i cannot access the document directly, i have to parse it before...

the livecycle:

filling the form -> submitting -> generating xml-struct on server-side -> return the xml struct -> parsing the string? so it becomes an xml doc

here is the function to parse the xml, maybe theres the error

Jame.helpers.xml.loadXML = function(_xmldata){
// code for IE
if (window.ActiveXObject){
var doc=new ActiveXObject("Microsoft.XMLDOM");
// code for Mozilla, Firefox, Opera, etc.
var parser=new DOMParser();
var doc=parser.parseFromString(_xmldata,"text/xml");
return doc.documentElement;

and the callback function, for "form submit success"

Jame.connection.login = function(f,a){
e = Jame.helpers.xml.loadXML(a.result);
//e = a.result
if(e.getAttribute("type") == "success"){

if the code is wrong, firefox would also return an error! but it doesnt... please help me, maybe my concept is wrong, what can i do so its working properly?

If you're building XML on the server, return an XML document, not a string. There's no pointing wasting the cycles on the client to parse the string into an Xml Dom if you don't have to.

ok got it, it was all the time xml response from the server, dont know why im parsing it again ;) now i use


in FF its still working, but in opera it still fails (with the same error) , there must be something else where. and i cant figure out what or where :(

do you got another tip for me? :D sorry for bugging you

here is the function i added to my form "submit button"

LoginSubmit : function(){
waitMsg:'Please Wait...Connecting...',
success:Jame.connection.login, //callback method if Form.submit was successful

even if my callback function Jame.connection.login is empty opera throws this error :(
