Re: Trying to write my own component - AGAIN
Thanks Bruno, I'm studying the source since yesterday :).
I was trying to code it in the encodeBegin, but nothing displayed. I'll try
to code in the encodeEnd() method, following the schedule like you said.

I think that the best option to see how to implement a component isdirectly check out the sources for the tomahawk/sandbox components.Every component has the component, tag, and renderer implementation.You can check the

the model to the value attribute (I guess it should be something likevalue="#{bean.graphicModel" (without the getter)). Take a look at theschedule component, as it accepts a custom model object.The encodeBegin is optional as long as your component does not render
any children. When a component has children, the method encodeBegin iscalled before and the encodeEnd afterwars. In your case, I guess youonly need the encodeEnd in your renderer object (recommended).HTH,

Trying to write my own component - AGAIN
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: , 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 Rafael Mauricio Nami
