injecting state object in custom engine service

["Mazhar, Osman (Home Office)" <ma...@lls.org>]

I am trying to inject/set a state object, defined in the same xml file, into
a custom engine service as follows:

 

<set-object property="myObject" value="state-object:myObject"/>

 

And I get the following error:

 

No object provider exists for prefix 'state-object'

 

I have already tried using prefix 'state' and that doesn't work either.

 

Any ideas what prefix to user here?

Try:

<set-object
  property="appStateMgr"
  value="service:tapestry.state.ApplicationStateManager"/>

Then:

class YourCustomEngine ... {
  Object getMyObject() {
    return getAppStateMgr().get("myObject");
  }
}

However, by default it's quite difficult to use a hivemind service
as the engine because there is general no particular reason to do 
that.
