How to make a custom component reRendered by a4j

[pfreitas]

Hey Fellows...

I created a plain custom component that extends javax.faces.component.html.HtmlGraphicImage...

What I want to do is reRender my component when a click in a a4j:commandLink. So I put the id of my component on the reRender list. Now when I click in the commandLink it calls the encodeBegin method of my component... I change some variables and as result the URL of src attribute should change... but nothing happens to the page... it's not being rerendered...

there is something I need to do for the changes I make in encodeBegin takes effect on the page??


sorry for possible english mistakes I commited... I came from BraziL!!

Thx!!!

I found the solution....

just for the records....

i should call these methods RenderBase.doEncodeBegin implementation:

getUtils().encodeId(context, component);
 getUtils().encodePassThru(context, component);
 getUtils().encodeAttribute(context, component, CHART_DATA_PARAM_NAME);

I still don't know what encodePassThru does... but it might do something...
the jump of the cat I guess is that encodeAttribute call...
so ... it works now... when I put my component's Id on a command link reRender list.... it does update my things on client side...
