A quick post about Gwt-Ext Charts.

Getting charts to work in GWT-Ext can be a little painful.

There is 3 things you have to make sure you have:

1 

<inherits name=”com.gwtext.Charts”/>

in your <YourApp>.gwt.xml

2

the gwtexux.jar file in your classpath, and of course the jar file should be wherever you are pointing to  ;).

3

Most importantly the swf file that is on wherever you set your express install, in the demo is set to

chart.setExpressInstall("js/yui/assets/expressinstall.swf");

and even tho i had my library where it should, for some reason for me it wasn’t uncompromising to the right path so I uncompressed what i needed to public/js.

Note: Sometimes the charts don’t actually work on hosted mode, so you should compile/browse and its there … in Firefox and Chrome but of course it doesn’t work on ie , this is depending on the version of flash you have.
