Well, I can confirm it The Prototype adapter is borked in 1.0
Using the BorderLayout (I was using /ext-1.0/examples/layout/complex.html to test with), loading a ContentPanel dynamically with something like this:
(or any of the other methods I've tried) to load a page that looks like this:
Using the prototype adapter the script inside the < script> block will not run, but making no other changes to complex.html except for switching the prototype adapter for the YUI adapter the script inside the < script> block will run when loaded.
<p onclick="alert('wth! Inline script works fine...');">Now is the time for all good men to come to the aid of their country</p>
alert( "...but script in a <Script> tag does not run" );
Here are the includes I am using for the adapters, paths verified 1,000 times and known to be good
