I linked the button's action attribute with a backing bean to see if I could invoke a method. No luck.
It seems actionListeners aren't triggering the construction of a backing bean, nor are they invoked in already constructed beans. I can only get my backing beans to initialize when they are linked to something like a button's text.
The value of the property '_checkUnload' is null or undefined, not a Function object.
The value of the property '_defaultTZ' is null or undefined, not a Function object.

Turns out I needed to modify my web.xml so that the <web-app> portion had a version="2.4" set. I believe this triggers JBoss to use the correct JSP version. Previously I had 2.5.
While this may have been part of the trouble, I also had modified the adf-faces-impl files to remove the 10_1_3_4 underscores. JDev wouldn't use the library if I didn't. However, this caused a few other problems. So I've got one set of files that work to compile in JDev and I've got another set that is put in the deployment's WEB-INF/lib directory.
