jThe latest jQPie has been released, you can download it http://projects.cyberlot.net/trac/jqpie/wiki/WikiStart.
The main thing in this release is the addition of an auto complete and a grid example based of the extjs library, One thing to keep in mind the css files provided by extjs will overrun pretty much any css you have, the main one being ext-all.css, It seems some things are set in here that are required for the examples to work but at the same time it styles pretty much every element in existence.
