Thanks, that should be usefull, but doesn't help on the issue that to get an
instance of a component it must be injected somewhere, and that somewhere's
template must have every component that eventually you will use (because I
can't inject a component in a class whose template doesn't have it), so it
will always load every posible component...
And this is one main problem: i wanna use an injected component that it's
not on any template on a explicit way. Is there any way to get an instance
of a component that is not present on any template?
By the way, there says:
"The component may have been injected via the Component annotation, or may
have been passed to the as a parameter".
I don't know how to pass a Component as a parameter in a phase render
method, I tried:
Object beginRender(MyComponent myComponent) { ... }
but myComponent variable is always null there...
What do you think?
Regards,
John
