If I create a new, valid war from scratch and copy it to standalone/deployments, AS7 will deploy it fine. Further, I can touch it or overwrite it and AS7 will redeploy it. But once I undeploy it, AS7 will never deploy it again, at least not by my touching it.

Also, if I break it and cause a failed deployment, AS7 will never attempt to redeploy it as a result of my updating it. Hence, I can't overwrite an invalid war file with a valid one and have it deploy.

To force a deploy, I must either rename my.war.failed to my.war.dodeploy or use the CLI.
