Re: How to stop (w/o exception)

Instead of the macro I'd just put it in an if statement.  Maybe I can try/catch stop exception in my servlet, but I may not always want to catch that.  There should be a [#abort /] directive or something to do that.

You could enclose your template body in a:

[#macro actuallyRenderThePage]
...
[/#macro]
[@actuallyRenderThePage/]

and then use [#return] from within the macro body. Of course, that
doesn't address more complex situations, as stopping gracefully from
several levels of macros or includes. In these cases [#stop/] is the
only reliable mechanism -- you'll just have to catch and ignore it at
your point of Template.process() invocation...
