> 2 places where error reporting can be improved is in 
> 1.  UIXComponentELTag.doStartTag()
> We could add a try/catch around the super.doStartTag(), do some severe logging (eg.log a scoped id) in response to exceptions, and re-throw. 
> 2.  UIXComponentELTag.createComponent()
> This might be a reasonable place to detect the cases where a component that you pull out of a component binding during createComponent() is already attached to some component tree- and thus the (severe) error is justified.
