quotes are lost from validation error message with omnifaces `o:validateMultiple`

Question

I am using Omnifaces 1.7 to validate multiple fields in my JSF 2 form. More precisely, I use the following snippet

<o:validateMultiple 
          id="activiteValidator" 
          components="programmeCreation programmeReport dateEcheance"
          validator="#{activiteControleFacesValidator}" 
          message="L'activité n'est pas cohérente." />

which works as intended except for one small glitch ; the quotes in the error message are lost when the message is shown because the validation error is triggered. This is what I get in the HTML in case of validation failed

Lactivité nest pas cohérente.

If you know what is wrong with this configuration or how I could circumvent that problem, I would be most thankful.

Update : if I try to escape the quote, it still doesn't work. When message="L\'activité", the HTML result is L\activité.

This is caused by the MessageFormat API which is under the covers being used for message formatting (substituting {0}, {1}, etc). The apostrophe (single quote) is actually an escape character.

You need to escape the single quote by another one in order to display it as-is.

<o:validateMultiple 
    ...
    message="L''activité n''est pas cohérente." />

An alternative is to use a curly right single quote.

<o:validateMultiple 
    ...
    message="L’activité n’est pas cohérente." />
