Thanks, good pointers! IncludeNotFound looks like it'd do the
trick, but for every #parse, not just the one I want to make
conditional.
Why is it that $engine.resourceExists($template) throws an exception
rather than returning false?

There's no canonical way of doing this within a template yet, but
there is the IncludeEventHandler which was added in Velocity 1.5.
There is even an IncludeNotFound implementation provided. You may be
able to set up a simpler, exception free solution using those.
Alternately, you could pretty easily create a VelocityTool that did
this.

Hi,
I'd like to have some construct like this in a template:
#if(templateExists($template))
#parse($template)
#end
Is there a canonical/approved way of doing this? I've put the
VelocityEngine into the context and tried:
#if($engine.resourceExists($template))
...
#end
But that still throws an exception when $template does not exist.
I want to
avoid the exception and simply skip #parse'ing if a template does
not exist
Thanks,
Erik
