[Zope3-Users] Problem creating custom z3c.pagelet error page

[andrew]

Hi Roger,

I finally got it sorted. The class providing the error handling needed
to implement our view marker interface, so the solution was:

class VortexNotFoundPagelet (NotFoundPagelet):
    
    zope.interface.implements (IVortexBrowserView)

and:

	<z3c:pagelet
	    name="index.html"
	    for="zope.publisher.interfaces.INotFound"
	    class=".VortexNotFoundPagelet"
	    layer="vortex.layer.IVortexBrowserLayer"
	    permission="zope.Public"
	    />

	<z3c:template
	    template="notfound.pt"
	    for=".VortexNotFoundPagelet"
	    layer="vortex.layer.IVortexBrowserLayer"
	    />

I'm not sure if this will apply to anyone else, but I post it simply to
close the loop. And I should add that pagelets are very cool :-)

Cheers, Andrew.
