[jboss-user] [JBoss Seam] - ClassNotFoundException while invoking EL function during ren

I wrote a simple EL function to retrieve the clientId of a UIComponentBase object -- I'm generating some javascript. The first time I load the page (without a submit), the page generates just fine, including the javascript output that successfully invoked my EL function from a h:outputText element.

However, when I submit the form it throws a ClassNotFoundException (for my EL function class) and generally freaks out after that. Now, obviously it should be able to find the class since it managed to find it on the initial rendering of the page.

Am I missing something about using EL functions in a JSF tag?
