null from CayenneRuntime.getThreadInjector()

Hello.

I am playing with serialization of cayenne objects in trunk. This is the first time I do (java) serialization of cayenne stuff. On deserialize I get the following.

org.apache.cayenne.CayenneRuntimeException: [v.3.2M1-SNAPSHOT Aug 23 2012 08:32:28] Can't attach to Cayenne runtime. Null injector returned from CayenneRuntime.getThreadInjector()
	at org.apache.cayenne.BaseContext.attachToRuntimeIfNeeded(BaseContext.java:141)
	at org.apache.cayenne.BaseContext.getEntityResolver(BaseContext.java:197)
	at org.apache.cayenne.Cayenne.buildId(Cayenne.java:529)
	at org.apache.cayenne.Cayenne.objectForPK(Cayenne.java:383)

It looks like I should do a CayenneRuntime.bindThreadInjector(Injector), but how should I create the Injector?

Regards,
Tore Halset.

Hi Tore,

Injector is encapsulated in CayenneRuntime, so... 

ServerRuntime runtime = // assume you have that, since you started Cayenne somehow..
Injector i = runtime.getInjector();
