'$wnd.Ext.StatusBar' is null or not an object

[PeteF]

Hi all,

I have installed gwt-ext through Maven plugin for eclipse. I am using
gwtext version 2.0.5.

I have added the following to MyApplication.gwt.xml:

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

<stylesheet src="GwtExt.css" />
<script src="js/GwtExt.js"></script>

I have also added the following to MyApplication.html:

<script type="text/javascript" src="js/GwtExt.js"
charset="utf-8"></script>

I am using some getext windgets and everything passes compilation.
When I run my application, I get the following error pointing to the
first line of code where I am using the gwtext widget:

Any ideas as to what I am missing and/or how I can fix this? Any help
would be greatly appreciated.

Hi

Take a look at my latest post to the "GWT 1.6 and GXT" thread I
started yesterday. It might help you get a bit further.

Thanks for your reply. I took a look at your posting and the entire
thread. The only js file I can find with the downloaded gwt-ext jar is
GwtExt.jar. All the postings related to this that I have found talk
about other javascript files (like gwt-all.jar, etc.) that I cannot
find in my downloaded 2.0.5 jar. Any other thoughts?

Thanks,
Payam

More specifically, I cannot find the following in my download gwt-ext
jar file:

/js/ext/resources/css/ext-all.css
/js/ext/adapter/ext/ext-base.js
/js/ext/ext-all.js

The only css file I can find is: GwtExt.css

I cannot find any ext directory as part of my download. The only
javascript directly under js directory is: js/GwtExt.js which I have
included in my MyApplication.gwt.xml file. There are other javascript
files under the following directories. Do I need to include any of
them if I want to use the code I have found at: http://gwt-ext.com/demo/#basicArrayGrid

/js/map/
/js/pagebus/
/js/sh/
/js/yui/


I am using gwt 1.6.0.

Any help would be appreciated.

Hi

No worries, although I haven't been any help yet.

I obviously have my environment configured incorrectly. Would you be so kind as to describe your setup in detail so I can make mine the same, please?

I am using Maven to get the libraries. Here is what I have in my
pom.xml for gwt-ext:

<repository>
<id>gwtext</id>
<url>http://www.gwt-ext.com/maven2/</url>
</repository>

<dependency>
<groupId>com.gwtext</groupId>
<artifactId>gwtext</artifactId>
<version>2.0.5</version>
</dependency>

The rest of my setup is included in my posts above.

Hope this helps. Please let me know whether you run into the same
issue when setting it up this way.

Again, take a look at my other thread. Nick has solved the problem for
us. I suspect you'll have to modify your maven script to get gxt-2.0.2
as well......

Assuming you're using gwt-ext, take a look at my blog: paulgrenyer.blogspot.com.
