This exception is reported when the ExtJS files don’t get included for some reason. This is discussed frequently in the Gwt-Ext forums and Google group.

Take a look at this thread for example: http://groups.google.com/group/gwt-ext/browse_thread/thread/21e9cd5a15b69093. A search of the forums should lead you to more such discussions.

Thank your reply. Thanks, Abhijeet

However I tested through your reply, I got following message.

com.google.gwt.core.client.JavaScriptException: JavaScript ReferenceError exception: Ext is not defined

I include SHA1.js file into my .gwt.xml file:

This including is true, isn’t it? What can I do?

Thanks,

Hi Khadaa, I am doing good. Thanx! And hope the same for you.
I had a look at Jeff Howden’s sample that you linked above. To use it, you will need to include the SHA1.js file from http://ext.vosandhowden.com/ux/crypto/Ext.ux.Crypto.SHA1.js in your host HTML. Then you need to write a native method to invoke the Javascript hash function

public native String hash(String message)/*-{
	return Ext.ux.Crypto.SHA1.hash(message);
}-*/;

You can then invoke this method to get the SHA1 hash of a string:

String hashValue = hash(textField.getText());
hashTextField.setValue(hashValue);

Didn’t get a chance to test this. See if it works.

Hello Khadaa,
You can request enhancements at the forums or better, create issues for them / add them to the UX project yourself!
I have created the issue for HTMLEditor at http://code.google.com/p/gwt-ext-ux/issues/detail?id=26.
I am not sure if Ill be able to make some time to take it up immediately. Hopefully someone else will.

In the meantime, you can include the JS files in your project and use some JSNI to get it working temporarily. Forum users will definitely render any help needed.

Abhijeet.
