Trying to write my own component - AGAIN

[Rafael Nami]

Hi everyone, and thanks for the explanations about packing a component.
Im trying to write now a Graphics component. I already have a GraphicFactory, that
receives a model object, and convert its attributes in coordinates. I'm trying to
follow the approach that is described in Core JSF - chapter 12. I just want to know one thing:
1 - How can I add something like:
<e:graphics value="#{bean.getGraphicModel}"/>, where this backingbean method returns this
model object, filling the component with the model object in one fellow swoop.
Did I have to do some Binding code, because it's just a output component.
Did I have to only write the encodeBegin() method in the Tag??

Thanks and Best Regards
