Cannot deploy exploded ear - could not be opened, does it exist?

I am evaluating v10 and am hitting a small problem that I cannot seem to solve.  I can build my project and generate the artifact correctly (.ear) file, but recieve the following error message when I try and deploy my exploded ear file to the JBoss application server:

[2011-03-15 11:46:07,291] Artifact myStuff:ear: Artifact is being deployed, please wait...
org.jboss.deployment.DeploymentException: url file:///home/me/IdeaProjects/MyStuff/out/artifacts/myStuff.ear/ could not be opened, does it exist?


I know the exploded ear directory is being created correctly.  I can see it on the file system (in my projects directory structure) and everything looks correct.  I can also directly copy and paste the exploded ear directory into my JBoss deploy directory and the appserver spins it up just just fine.  It is only when I try to deploy using the IntelliJ IDE v10.  Oddly enough, It works correctly in v9.

Has anyone see this before? Have i missed a check box some where in the latest version?

- Thanks
