Re: Hivemind eager loading of a service which references tapestry services is not possible

Wed, 25 Apr 2007 18:37:08 -0700 

So my service needs to implement an interface? which?

One possibility is that the service you are contributing does not implement 
the correct interface, though I'm pretty sure there should be checks in
place for that. I wrote the ChainBuilder code in HiveMind a couple of years 
back!

Basically, your contributions are mixed in with Tapestry's and anybody
else's to form a chain-of-command.  The exception inside the constructor
indicates that there was an issue converting the List to an object array (of 
the service interface type) and the most likely cause there is that your
contributed service is the wrong type.

Howard,

At present this is all the output I'm getting, I haven't enabled
Log4j/Logging yet though (haven't decided on the best way to do so).
