Problem with pass parameter Using @Environmental
I have a 2 nested component.
I pass Parameters Using @Environmental service.
Code in Outer Component:
void beginRender() {
environment.push(MyData.class, data);
}
void afterRender() {
environment.pop(MyData.class);
}
Code in inner Component
@Environmental
private MyData data;
It works well.
Then I want to put my first component in an ProgressiveDisplay,
When should I call environment.push() ?
I try like this:
In my outer Component:
@OnEvent(EventConstants.PROGRESSIVE_DISPLAY)
void onLoad() {
environment.push(MyData.class, getData());
}
I think this would work, but if it works, where should I call environment.pop()?
I got an Error:
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's strange that It says MyData not found, but there are MyData in availableValues.
Many Thanks.

It's the object, not null.
It's strange that on the error page there is org.test.MyData, but I can't get it.
Now I use Tapestry 5.3-beta-21, It works when I use Tapestry 5.2.6.

The Enviroment is tied to a ThreadLocal in the Request, so if you
don't pop MyData manually, it should be cleared out automatically when
the Request ends.
I'm not sure why MyData is not found on the Environment Stack - does
getData() return an actual object or a null?
