Wicket component strings

Wicket components have a convenient getString method to load a (translatable string from a properties file associated with the component (or any component in its hierarchy). It also allows you to provide parameters to those strings in the form “${count} new messages” where count is looked up as a property of the model you pass to getString.

Sometimes, however, I’d prefer to just have simple numbered parameters and provide them as varargs to getString(). So, in my properties file, I’d have “${0} new messages” and I’d call “getString(id, 15)” to get “15 new messages”. To do this, you need to add a method something like this:

This method takes your varargs and creates an object array which the standard getString function can use to look up your parameters by index.
