Re: [WebMacro-user] #bean...scope=session no longer working?

[Rab W. <ja...@ya...>]

I tried your example and it works ok! But, my simple
test bean still refused to cooperate when
scope=session. I've got logging in the constructor and
the test bean is getting instantiated *every* time the
page loads (I don't think this is correct behaviour
for session scope). How can it be instantiated, but my
template not 'see' any methods on the bean?

I'm curious about your comment about my BeanDirective
security, are you referring to something in
webmacro.properties?

Many thanks.
