Answer 1

If you look up the default.deleted.message key in your messages.properties you'll see it looks like

default.deleted.message={0} {1} deleted

Simply add a new line with the key and value you want.

inbox.deleted.message={0} messages deleted

and use it in your controller

flash.message = message(code: 'inbox.deleted.message', args: [deletedMessageCount])

Of course, you'll need to define a value for deletedMessageCount before using it.

Answer 2

You could do this:

    def device = MessagingDevice.findByPhoneNumber(params.phoneNumber)

    // invoke deleteFromDevice on domain object, which returns number of objects deleted
    def count = messageInstance.deleteFromDevice(device)
    if (count) {
        flash.message = message(code: 'default.deleted.message', args: [message(code: 'message.deleted.label', default: '{0} Messages deleted'), count])
        redirect(action: "phone", params:[phoneNumber:params.phoneNumber])
    }

and in your messages.properties

message.deleted.label={0} deleted

Answer 3

in code:

int count = 5 //number of deleted messages

flash.message = message(code: 'default.deleted.messages', args: [message(code: 'messages.label', default: 'Messages'), count])

in messages.properties:

messages.label=Messages
default.deleted.messages={1} {0} deleted
