Hi All
Sorry to keep perpetuating this, but I didn't like the widgets in GXT
as much as GWT-EXT, so I'm back on with GWT-GXT.
I've:
1. created a GWT 1.6 project with the plugin.
2. Added gwtext.jar to war/web-inf/lib and to my project dependancies
3. Added the following to my .gwt.xml file:
<inherits name='com.gwtext.GwtExt' />
...
<script src="js/GwtExt.js" />
4. Modified my entry point to show a simple dialogbox:
MessageBox.confirm("Confirm", "Are you sure you want to do that?", new
MessageBox.ConfirmCallback()
{
public void execute(String btnID)
{
System.out.println("Button Click : " + Format.format("You
clicked the {0} button", btnID));
}
});
When I run the app in hosted mode (even following a compile),
everything loads ok but I get the following erro when I click the
button that should show the dialog box:
[ERROR] Uncaught exception escaped

Any idea what I'm doing wrong? Have I missed something in my
configuration somewhere?
