Simple way to use parameterised UI messages in Wicket?

Question

Wicket has a flexible internationalisation system that supports parameterising UI messages in many ways. There are examples e.g. in StringResourceModel javadocs, such as thi

Answer 1

When faced with something like described in the question, I would now use:

.properties:

msg=Saving record %s with value %d

Java:

add(new Label("label", String.format(getString("msg"), record, value)));

Why I like it:

• Clean, simple solution
• Uses plain Java and nothing else
• You can replace as many values as you want (unlike with the ${} trick). Edit: well, if you actually need to support many languages where the replaced values might be in different order, String.format() is no good. Instead, using MessageFormat is a similar approach that properly supports this.

Disclaimer: this is "too obvious", but it's simpler than the other solutions (and definitely nicer than my original replaceAll() hack). I originally sought for a "Wicket-y" way, while this kinda bypasses Wicket—then again, who cares? :-)
