Application message bundle

Question

I'm setting up an application level message bundle to handle error messages as described in other threads. I have a question about validator messages and the insertion of maximum and minimum field values. I've seen these examples and I have the following assumptions:
{0} and {1}, these are for numeric range values
'{0}', this is for numbers
"{0}", this is for Strings
So, If I put these in my messages (listed below) am I safe to assume that jsf will replace them with the appropriate values?
Thanks!
javax.faces.component.UIInput.REQUIRED=Please enter a value
javax.faces.validator.NOT_IN_RANGE=Please enter a value between {0} and {1}
javax.faces.validator.DoubleRangeValidator.MAXIMUM=Please enter a value less than '{0}'
javax.faces.validator.LongRangeValidator.MAXIMUM=Please enter a value less than '{0}'
javax.faces.validator.DoubleRangeValidator.MINIMUM=Please enter a value greater than '{0}'
javax.faces.validator.LongRangeValidator.MINIMUM=Please enter a value greater than '{0}'
javax.faces.validator.LengthValidator.MAXIMUM=Please enter a value less than "{0}" characters
javax.faces.validator.LengthValidator.MINIMUM=Please enter a value greater than "{0}" characters

Answer 1

I don't know about the quotation marks and all, seems to print strings just fine for me when I leave the quotes out.
{0}, {1}, {2}, ..., {n} represent array indexes. You'll need a message factory to properly create messages that input the appropriate array elements in the right message spots.
If you don't use the message factory, you'll simply get the message character for character. i.e. "Please enter a value between {0} and {1}"
To create a MessageFactory, just copy the one JSF uses internally. You can find it in the javax.faces.component package (in the jsf-api.jar file).
To get a proper message out of the factory, call it using the getMessage() method. Something like this:
     FacesMessage msg = MessageFactory.getMessage(context,
          "javax.faces.validator.NOT_IN_RANGE", new Object[] {new Integer(1), new Integer(5)});This will return a FacesMessage that contains this message:
"Please enter a value between 1 and 5"
Hope this helps,
