I have a zone, and many nested components in it. I pass objects to these components by Environmental Service.
The first time page render is ok. But when I click an Action link which will refresh the zone, I can't get Environmental Object. And I get an Error like this: org.apache.tapestry5.ioc.util.UnknownValueException No object of type org.test.MyData is available from the Environment. availableValues Environmentals: org.apache.tapestry5.RenderSupport org.apache.tapestry5.ValidationDecorator org.apache.tapestry5.internal.services.DocumentLinker org.apache.tapestry5.services.ClientBehaviorSupport org.apache.tapestry5.services.FormSupport org.apache.tapestry5.services.Heartbeat org.apache.tapestry5.services.javascript.JavaScriptSupport org.test.MyData It says No object of type MyData is available, but in availableValues, there is my MyData. strange. I use tapestry-rc-3 now. But it works when I use tapestry 2.6.
