I think there is a typo, and the label is supposed to come from
UIComponent label = getChildren().get(1);

I’m trying the code now.

writer.startElement(“td”, label);

Sorry to have to add to my own post, but a clarification may be necessary. I keep saying “of the component you are overriding.” This is misleading. You are overriding the combination of JSF component and renderer. You are only writing/extending the renderer class.

Erik,
You can specify a custom renderer for a standard jsf tag. I wrote one for the richfaces inplaceSelect.
N.B. I did this for facelets. JSP may need a bit more.
I created a custom taglib.xml file. In there, I define a new tag item. In this item, I specify a component tag. In the component tag, define the component-type tag to match the JSF comonent type you are overriding. In my case, this was: org.richfaces.InplaceSelect. Then, add a renderer-type tag and give it a new type ( com.myDomain.InplaceSelectRenderer ).

Then, in your faces-config.xml, define a render-kit with a new renderer tag. 3 tag are needed for the renderer: component-family, renderer-type, and renderer-class. The component-family needs to match the family of the JSF component you are overriding. The renderer-type must match the type specified in your custom tag definition. The class is the FQN of your renderer class.
I fumbled my way through this, trying different combos. This way worked for me. Hope it helps!

Good and nice post.

I have a problem. Perhaps you can help me.

Your component is self-rendered, but I need to use another class for render.

It seens like tableRow.renderer has no effect in your example.

Can you explain me how to do a not self-rendered component with Facelets? I have tried without any success until now

Thanks in advance.

Hi!

Nice tutorial. How would you go about implementing a custom renderer for a standard jsf html tag with Facelets?

Or, to be precise, is there any way of substituting a custom renderer which doesn’t render a bunch of HTML table tags instead of the standard one, for all instances of h:selectOneRadio, while still retaining all of that tag’s functionality in terms of bean binding, etc.

The documentation on this type of stuff is certainly pretty thin…

Thanks.
