How To Use I18N Messages In A Grails Plugin -


i've added new exception plugin:

class unzipexception extends runtimeexception {     string message     string defaultmessage     string filename }  . . .          else {             throw new unzipexception(                 message:"grailsant.unzipexception.badfile",                 defaultmessage: "invalid zip file: ${zipfile}",                 filename: zipfile)         } ...

and in plugin's messages.properties have:

grailsant.unzipexception.badfile=invalid zip file: {0}

two questions:

  1. how {0} filled in filename?

  2. can application override grailsant.unzipexception.badfile message?

(1) seems has done app:

try {   . . . } catch (org.grails.plugins.grailsant.unzipexception e) {      flash.message = e.message      flash.args    = [e.filename]      flash.defaultmessage = e.defaultmessage }

(2) yep, if message.properties in app has same key plugin, app's values used.
