Daniel Spicar commented on CLEREZZA-460:
----------------------------------------

HI reto,

I am not really sure what you mean.

Are you saying that:

Bundle/Service A registered an SSP x with RenderletManagerImpl.
Service B wants to override SSP x using RenderletManagerImpl.
A is restarted during the override phase (for what reason do you mean? because 
of the unregister call in the update process or by coincidence for some other 
reason?)
B disappears before it finishes overriding?


> Use whiteboard pattern for Renderlets

> The current mechanism for renderlets is overly complex. Instead of describing 
> renderlets in a graph rendelets should be services that have properties 
> indicating the rdf type and the mode-pattern they handle.
> The priority for selecting renderlets should be:
> - type, according to type-priority list
> - length of regex math (the matching regex with the most alphanumeric 
> characters wins)
> - startlevel of the bundle providing the service
