Hi everyone!!

Thanks for all your response.
Everything is now working for me.
I was doing a mistake in the call of the component A in a third one (C) as if A require the binding value. (A is the template that all pages should use).

But i have another question (I don't know if it is best to make a separate post):

Question : What is the best way to make a dynamiq page inclusion system?

I have a lot of custumized components those i would like to listed on a central page (this page use my template).
And i want that depending of the clicked link the corresponding components is load in the content area ofmy central page.

Thanks for your help.

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.

What is your HTML? You need to wire up your binding with the actual method/ivar of your component A:

…
<wo:B userAccount="$account" />
…

and in A.java:

public MyAccountClass account = …;
