Ext is not defined

Hello,
I posted this in GWT Forums, but they told me I should post here... So
here it goes:

I am experiencing some trouble using GWT-Ext in hosted mode. I have an
application that uses GWT classes, GWT-Ext and GWT-Extux. Today I
found out using Firebug that there are some JavaScript errors:

Ext is not defined
[Break on this error] Ext.ux.Multiselect = Ext.extend(Ext.form.Field,
{
Multiselect.js (line 3)
Ext is not defined
[Break on this error] Ext.namespace("Ext.ux");
DDView.js (line 5)
Ext is not defined
[Break on this error] Ext.ux.MultiMonthCalendar =
Ext.extend(Ext.Component, {
MultiMonthCalenda... (line 16)
Ext is not defined
[Break on this error] Ext.namespace('Ext.ux.grid');
BufferedGridDragZ... (line 14)
Ext is not defined
[Break on this error] Ext.namespace('Ext.ux');
BufferedGridToolb... (line 21)
Ext is not defined
[Break on this error] Ext.namespace('Ext.ux.grid');
BufferedGridView.... (line 19)
Ext is not defined
[Break on this error] Ext.namespace('Ext.ux.data');
BufferedJsonReade... (line 11)
Ext is not defined
[Break on this error] Ext.namespace('Ext.ux.grid');
BufferedRowSelect... (line 11)
Ext is not defined
[Break on this error] Ext.namespace('Ext.ux.grid');
BufferedStore.js (line 11)
Ext is not defined
[Break on this error] Ext.ux.ManagedIFrame = function(){
ext-ux-miframe.js (line 49)

My application works with Firefox and hosted mode, but not with IE. My
Module HTML and XML are:
<html>
<head>
<title>title</title>
<meta http-equiv="Content-Type" content="text/html;
charset=UTF-8" />

<script type="text/javascript"
src="la.package.Module.nocache.js"></script>


<link rel="stylesheet" type="text/css" href="js/ext/resources/css/
ext-all.css"/>
<link id="theme" rel="stylesheet" type="text/css" href="js/ext/
resources/css/xtheme-gray.css"/>

<link rel="stylesheet" type="text/css" href="css/digitel-
ext.css" /

<link rel="stylesheet" type="text/css" href="css/style.css" />

<script type="text/javascript" src="js/ext/adapter/ext/ext-
base.js"></script>
<script type="text/javascript" src="js/ext/ext-all.js"></script>
</head>

<body>
<iframe id="__gwt_historyFrame" style="width:0;height:0;border:
0"></iframe>
<table cellspacing="0" cellpadding="0" border="0" width="100%"
align="center">
<tr>
<td align="center" id="headerSlot"></td>
</tr>
<tr>
<td align="center" id="contentSlot"></td>
</tr>
<tr>
<td align="center" id="footerSlot"></td>
</tr>
</table>
</body>
</html>

<module>

<inherits name='com.google.gwt.user.User'/>


<entry-point class='la.package.Module'/>

</module>

I figured that the 'Ext' is not defined error could be caused by the
order of the javascript. I tried putting the
la.package.Module.nocache.js script as my final script, which
apparently solves the error. However, in hosted mode nothing is
rendered and it only displays a white screen:
...
<head>
<title>title</title>
<meta http-equiv="Content-Type" content="text/html;
charset=UTF-8" />


<link rel="stylesheet" type="text/css" href="js/ext/resources/css/
ext-all.css"/>
<link id="theme" rel="stylesheet" type="text/css" href="js/ext/
resources/css/xtheme-gray.css"/>

<link rel="stylesheet" type="text/css" href="css/digitel-
ext.css" /

<link rel="stylesheet" type="text/css" href="css/style.css" />

<script type="text/javascript" src="js/ext/adapter/ext/ext-
base.js"></script>
<script type="text/javascript" src="js/ext/ext-all.js"></script>

<script type="text/javascript"
src="la.package.Module.nocache.js"></script>
</head>
...

I am using gwt-1.4.61 (linux), gwtext-2.0.1, and gwtextux-0.1.1
Could anyone please help me on this one?

Thanks a lot!

Hi David,

"I figured that the 'Ext' is not defined error could be caused by the
order of the javascript."

Yes, thre browser need to load first the Ext resources...

I noticed that you didn't post a complete module definition (perhaps
you want to resume), but this a piece of code taken from the GWT-EXT
tutorial (http://gwt-ext.com/wiki/index.php/
Tutorial:Introduction_to_GWT-Ext_2.0#Configuring_Your_Application)

<inherits name='com.gwtext.GwtExt' />

<entry-point class='com.mycompany.mypackage.client.HelloWorld' />
<stylesheet src="js/ext/resources/css/ext-all.css" />
<script src="js/ext/adapter/ext/ext-base.js" />
<script src="js/ext/ext-all.js" />
</module>

"However, in hosted mode nothing is
rendered and it only displays a white screen"

Perhaps, as the resources are relative, they are not relative to the
host... :-/

I hope it helps...
regards,

Leo

Hi Leo,
thanks for your attention.
Yes, in fact that is not my complete module definition. I revised it
according to the tutorial, removing the javascripts from the html and
declaring them on the module xml. My current configuration is:

Module XML:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

<entry-point class="la.integra.ui.gwt.client.ConfModule"/>

<stylesheet src="js/ext/resources/css/ext-all.css"/>
<stylesheet src="js/ext/resources/css/xtheme-gray.css"/>

<servlet class="la.integra.ui.gwt.server.ServiceLoggerImpl" path="/
gwt/services/ServiceLogger"/>
<servlet
class="la.integra.ui.gwt.server.ServicePropertiesEditorImpl" path="/
gwt/services/ServicePropertiesEditor"/>

</module>

The html is:
<html>
<head>
<title>Modulo de Configuración. Integra</
title>
<script language='javascript'
src='la.integra.ui.gwt.ConfModule.nocache.js'></script>

</head>

<body>
<iframe id="__gwt_historyFrame" style="width:0;height:0;border:0"></
iframe>

</body>
</html>

With this configuration, everything works ok on hosted mode but the
'Ext' is not defined remains.

I could not move the script declaration to the body since it doesn't
work in hosted mode, I raised the loglevel of the shell and it seems
that the request for the module javascript is never made. I also
watched the logs when the javascript order is [ext, my module]. There
are a lot of requests but one request never occurs:
[TRACE] Request 40: http://localhost:8888/la.integra.ui.gwt.ConfModule/hosted.html

Leo: what do you mean by "Perhaps, as the resources are relative, they

are not relative to the

host..."?
Maybe you mean that when using hosted mode the resources are not
found? I don't think this is the problem since changing the order of
the javascript fixes the problem on hosted mode.

Best regards,
David

David... reviewing your exception trace, I think that your problem is
that the gwt-ext-ux library is old... (you said that you're using
gwtextux-0.1.1). Try to use the last one, (not from "Latest Builds"
link, download it from the gwt-ext-ux project - the zipped project).
I'm using the gwtextux-0.2.
Perhaps that is the solution.

Let me know...

Leo

Leo, I tried your suggestion but it didn't solve the problem. Perhaps I should also upgrade to gwt-ext 2.0.3?
Although I fear that something else could break, I will try to upgrade. But first, I will try the sample applications on browser and hosted mode. I'll keep you updated...

Thanks a lot...
David

Hi Leo

I am currently using gwt-ext-ux in version 0.2 , but i still got the
exact wrong message in normal web mode , but it is fine in hosted
mode. I don't know why, is it possible that it is caused by the
compatibility problem between gwt-ext-ux and gwt-ext ? because i am
using gwt-ext in version 2.0.2 not the latest 2.0.3
