Mike,
In this incarnation of the problem there appears to be some bad html
characters generated in the get() method. The script is now being
dumped to the browser window with the stack traces. I've include all
of the output.
Look for this chunk of code in the get method.
----------------------------------------------------------------------
// require a trailing slash.
var path;
path = context.getRequest().getPathInfo();
<b> if (path.charAt(path.length-1) != '/')
</b> {
app.redirectTo(context,path+"/");
return;
}
-----------------------------------------------------------------------
Any ideas?
