7:55 a.m.
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?
