Usage of ApllicationState Object
Hello
I have a question about the usage of an ApplicationState object.
Can I use the @ApplicationState only in the com.application.tapestry.components and com.application.tapestry.pages packages?
Or is it also valid in for example com.application.tapestry.beans package?
Because I have an ConversationManagerImpl class the isConversationsExists() always returns false.
When I call conversationManager.startConversation(..) it prints false.
package com.application.tapestry.beans
public class ConversationManagerImpl implements ConversationManager {
@ApplicationState(create=false)
private Conversations conversations;
private boolean conversationsExists;
public boolean isConversationsExists() {
return conversationsExists;
}
public String startConversation(Object target) {
if(!conversationsExists) {
conversations = new Conversations();
}
System.out.println("conversation exists: " + isConversationsExists());
}

That's absolutely correct for the @ApplicationState annotation, but you
can still get and set ASO values using the ApplicationStateManager service.

afaik you can only use ASO's from pages, components, mixins or base
packages.
(from http://tapestry.apache.org/tapestry5/guide/component-classes.html)
"Component classes must exist within an appropriate package (this is
necessary for runtime code transformation and class reloading to
operate).
These packages exist under the application's root package.
For pages, place classes in root.pages. Page names are mapped to classes
within this package.
For components, place classes in root.components. Component types are
mapped to classes within this package.
For mixins, place classes in root.mixins. Mixin types are mapped to
classes within this package.
In addition, it is common for an application to have base classes, often
abstract base classes, that should not be directly referenced. These
should not go in the pages, components or mixins packages, because they
then look like valid pages, components or mixins. Instead, use the
root.base package to store such base classes."
