hi angelo,
you can take a look at the Autocomplete mixin in tapestry-core... this is
a example
of a mixin creating javascript code
a mixin is very much alike a component as it has the same render phases.
for
example a component has a beginRender phase, a mixin too. The difference
is that a mixin can be attached to a component.
if a mixin is added to a component its render phase methods (event) are
called
before the component's methods. if the mixin has the @MixinAfter
annotation it will
be called after (you can attach multiple mixins to a component).
example:
public class MixinA() {
void beginRender() {System.out.println("mixin A")};
}
@MixinAfter
public class MixinB() {
void beginRender() {System.out.println("mixin B")};
}
public class Comp() {
void beginRender() {System.out.println("comp")};
}
@Component @MixinClasses(MixinA.class,MixinB.class)
Comp c;
the outcome will be:
mixin A
comp
mixin B
because mixins are like component you can use the markupwriter to
generate
code or inject services to, for example, generate javascript for the
component
through PageRenderSupport. mixins offer code reuse accross multiple maybe
totaly different compnents (separation of concerns)
i hope this helps ! more is available from the docs and mailing list :)
g,
kris

Hi Kris,
mixin is interesting, is there a simple sample that I can learn from ?
thanks.
