Well, I played around and I found a solution to my value binding problem.
In the tag I have a setValueBinding method that I copied from the Core JavaServerFaces book. It looks like this now:
public void setValueBinding(UIComponent component, String attributeName,
String attributeValue) {
FacesContext context = FacesContext.getCurrentInstance();
Application app = context.getApplication();
ValueBinding.vb = app.createValueBinding(attributeValue);
component.setValueBinding(attributeName, vb);
// Adding this line of code makes it work
component.getAttributes().put(attributeName, vb.getValue(context));
}
I noticed that the Renderer was getting the value from the component.getAttributes. So I added the put and it started working. I'm not sure if this is what should have been done, but it certainly does the job. The tag extends the UIComponentTag. Since this 1 line fixed the problem I didn't think anyone would need any other code. Let me know if you do though.
As I said, this worked fine with JSF 1.1.01 without the 1 line that I had to add.
Hope this helps someone to figure out what the problem was.
Thanks,
Ray
