The ant target, runappserver, is an ant macro included with the gae
sdk.
It does the same thing that dev_appserver does. The problem I'm having
is that the HelloWorld.howdy snippet is suppose to return
<span><a href="?login=">Log in</a></span>
but it doesn't. The only thing displayed is <li>Home<li>
I can trace the running code to the point where S.param("login")
matches Empty,
but that's about it.
Any idea why that is happening?
