How to get a localized message from enum displayed

Question

i have for instance an

enum State { OK, WARN, ERROR }

and a message.properties with following keys:

my.state.OK=Ok
my.state.WARN=Warning
my.state.ERROR=Error

and given a bean with a property of type State, for instance, bean.state, i would like to display the text for the property's state.

something like:

#{text['my.state.' + bean.state]}

this does not seem to be possible just because the + operator does not work on strings.

any work around?

never mind, i got it: `` and `#{text[msgKey]}` – mmoossen Nov 28 '12 at 13:33 — mmoossen, Nov 28 '12 at 13:33

Add an extra property to the enum representing the label key.

public enum State {

    OK, WARN, ERROR;

    private String labelKey;

    private State() {
        this.labelKey = "my.state." + name();
    }

    public String getLabelKey() {
        return labelKey;
    }

}

So that you can reference it as follows:

#{text[bean.state.labelKey]}

This way you don't need to repeat <ui:param name="msgKey" value="my.state.#{bean.state}" /> over all place.
