I am using the help-balloons plugin
I would like to use it parametrized. I mean, the messages should come from a properties file. In the documentation appears the following:

```
 <g:helpBalloon code="user.name" suffix=".help"/>

```

*In this last example, the code attribute is used to look up the balloon's title within the message bundle and then the suffix is added to the code (producing user.name.help in our example) as the key to be used for looking up the content of the balloon.*

My question is:

Where should be located this properties file (message bundle)?

Can I have one message bundle per controller?
