Subject: Re: Query loaded components and services?

   

For this I am looking a way to query Avalon/Merlin for which 
components are currently deployed, and information about them. Do 
anyone have some input on how this should be done from a loaded 
component? (The Console is a Block itself, that is included 
     

in another Block).

There is a small problem; Classloaders. They will protect 
components to reach each other's guts.
   

I figured it would be tricky! One nice feature of Merlin is the isolation of
the components really, but it does create some complexivity in some cases,
such as this one.
 

One possible solution that may work, would be to create the 
console as a LifeCycle extension, as all components will "fly 
by" in those hooks.
   

Thanks for the pointer, I was thinking about this approach. Have not looked
into lifecycle extensions earlier. Looked through it now, and it seems like
it is necessary to tag each component (in the meta information file) for the
lifecycle handler to be called. Is this the case? 

Yes - at least for the moment.
A non intrusive listerner will arrive sometime soon which is probably 
what yor really need.

Stephen.
