By looking at the code I cannot see any reason why the ChartRenderer cannot
get hold of the EL bound value property. Can you put the model inside the
bean for e.g. #{bean.model} for the chartModel and #(bean.component} for the
component.
Another thing that you can try is to get the trinidad source code and debug
the
org.apache.myfaces.trinidadinternal.renderkit.core.desktop.ChartRenderer.encodeAllmethod
to see what the issue is.
