Description

When using StringResourceModel one can add property expression into the resourceKey.
As documentation states: expression will be evaluated if the model parameter is not null.
But when parameter is null, with given example:

new StringResourceModel("my.resource.${my.propertyValue}"), myModel);

one can expect the need to provide

my.resource.null

resource key (same case as with DropDownChoice).
In fact, Wicket is searching for

my.resource.${my.propertyValue}

(literarily) instead which is just wrong.
