AS5 is not reliably picking up changes in exploded EAR

I have an explode ear file (directory) - see attached file: ear.jpg

When I deploy the exploded ear file to JBoss AS 4.2.3 and later want to update a xhtml file in the exploded ear by my ANT script everything works fine (i.e. I can refresh my browser and see the changes without redeployment of the ear or war):

<!-- Target: deploy.xhtml.to.jboss -->
<target name="deploy.xhtml.to.jboss" description="Deploy xhtml files to JBoss" if="deployed">
<copy todir="${jboss.deploy.dir}/${jboss.context.path}/${war.file.name}/xhtml">
<fileset dir="${view.dir}/xhtml" includes="*/"/>
</copy>
</target>

Because the exploded ear file is not copied to JBoss tmp dir.

But JBoss AS 5 always makes a copy of my exploded ear file and copies it to the tmp dir where it's the current 'working copy/version' used by JBoss AS - see attached file: tmp-ear.jpg
My ANT task will not work anymore because the 'working copy/version' used by JBoss AS now is in the tmp dir and not in the deploy dir.

I really don't want to 'touch' web.xml (or other meta files) to trigger a full redeployment when I need to make changes to my web files (xhtml, css, javascript, images etc.).

Could we please have the 'old' behaviour from JBoss AS 4.2.X implemented into JBoss AS 5 - or is there a workaround to above problem?
