doesnt make sense? why have an indirection for a model which is already itself an indirection.

> Would be handy, e.g. for labels which are to display different strings depending on runtime logic.
> Ex:
> new Label("conditionalLabel") {
> public IModel getModel() {
> return new StringResourceModel(condition?"mystring.yes":"mystring.no", this, null);
> }
> }
> Workarounds I can think of are:
>  * using a PropertyModel, pointing to a getter outside conditionalLabel
>  * overriding onBeforeRender in order to re-set the model before each time the component is rendered
> Both options do not seem very straightforward to me.
