Freemarker Tips

I like FreeMarker. It's simple, functional and pretty fast tool.
In project we are using Freemaker with SpringMVC.

To work with message bundle are used few macros, one of them is spring.messageArgs. So today I've spent some time on searching how to pass argument to it. There was only one argument and, obviously, I was expecting that this macros could be used in next way:
<@spring.messageArgs "some.message.key" "argumentValue"/>

Unfortunately it's not so easy :(. The macros is calling method that accepts arguments as an array of objects. And string "argumentValue" isn't an array. So I found next simple solution:
<#assign args = ["Ruslan"]/>
<@spring.messageArgs "" args/>

where = Hello {0}!

Another interesting thing about Freemarker is the way you can print numbers. If you want to print number value in argument X as a regular number rather than formatted number, you may do it in next way ${X?c}. I always forget to add ?c suffix and later receive many errors. Fortunately, it's possible to use #{X} that has the same effect. I found that it saves my time.
