T5.1: componentSource with an activation context

[Jack Nuzbit <fn...@googlemail.com>]

Hi,

Is there a way to create Pages and initialise their activation context at a
service level?

ComponentSource can give me Component instances but casting it to my page
instance results in a ClassCastException due to the different classloaders.
Is there a way I can set an activation/event context in this component using
existing Tapestry services?

This thread does mention that I could use an interface defined outside of
the component/page/mixin packages but it feels like there might be a way to
hook into the existing tapestry context behaviour...

Thanks in advance for any help.

Cheers,

Jack

Thanks Thiago, that's just what I was looking for.

I'm curious about what you're trying to accomplish here. :)

I'm essentially trying to build a managed flow of pages. I have some core
workflow functionality but it varies across different apps and would like to
centralise the configuration in a contribution on a per-app basis. Sounds
fun right? :)

You can try doing exact the same thing components do to trigger events:  
the ComponentResources triggerEvent(...) method in your returned page  
instance. To get the ComponentResources for a given Component, use  
getComponentResources(). Never tried it myself, though.
