Hi Ronald,
is your B component syncronizing bindings?
If so, your B instance should receive a call equivalent to «
b.takeValueForKey(session().authenticatedUser(), “userAccount”); » so you
should comply to KVC for this key (public ivar, get/set method .. your choice)
to get it assigned and available.
If your B component is non-synchronized, then you have to get it whenever you
need it:
« User user = this.valueForBinding(“userAccount”); »
Also, since your B component is in a framework and is aware of the concept of a
userAccount, I would try to keep the dependency as loose as possible and NOT
add coupling directly with the session object.
But if you absolutely have to do it (last resort), it could be done with simple
KVC:
« User user = (User) session().valueForKey("authenticatedUser”); »
or even:
« User user = (User) valueForKeyPath(“session.authenticatedUser”); »
Ways of passing generic/contextual objects from the front-end layer to the
lower end without adding too much coupling is by going through the
editingContext.userInfo dictionary, or through the current thread userInfo
dictionary (see ERXThreadStorage). Those 2 objects are available in most lower
level objects and can be set from the upper level just as easily.
