JSF 1.1: Placeholder {0} of required inputText won't be replaced - jsf

Question

I have the following JSF code for a required input textfield:
<h:inputText id="System"
label="System"
value="#{MyBean.system}"
maxlength="2"
required="true">
Then when the user does not input the value for this field, the following message is displayed: "{0}: A value is required." The issue is: JSF is not replacing the placeholder {0} with the inputText's id, as it was supposed to do.
I have this kind of code all over my system and it was previously working well. Recently I switched to a build using Maven and I'm likely to have changed the version of some lib, which is now causing the application not to work properly. I tried to make sure the versions of the libs declared in my POM match the ones I had before but even son this problem sticks.
The JSF-related libraries declared in my POM are the following (plus I'm using JBoss 4.0.5 GA):
<dependency>
<groupId>org.apache.myfaces.core</groupId>
<artifactId>myfaces-api</artifactId>
<version>1.1.7</version>
</dependency>
<dependency>
<groupId>org.apache.myfaces.core</groupId>

</dependency>
<dependency>
<groupId>org.richfaces.ui</groupId>
<artifactId>richfaces-ui</artifactId>

</dependency>
Any clues?
Thank you!

This is not available in JSF 1.1. This was introduced in JSF 1.2.
Upgrade to JSF 1.2. It's 100% compatible on a JSF 1.1 environment. Additional bonus is that many, many logic and performance bugs are fixed in latest JSF 1.2.
