Validation messages HTML formatted, best practice?

[sl0005]

I'd like to inform user about validation problems with HTML-formatted messages, but if I use standard tag h:message, it looks like there is no HTML support in it.

                    <h:outputLabel for="email" value="Email" />
                    <h:inputText id="email" value="#{user.email}"/>
                    <h:message for="email"/>

What is the best solution here to have the error message formatted?

I don't understand really well your question.

What do you mean by HTML Support? You mean change font colors and etc?

I mean do not escape HTML output (like in h:outputText there is an attribute escape).

I want for example to highlight the wrong letters in user input with red background, like this (wrong letters are b and e) :

Some letteres are wrong in "a<span class="wrongLetter">b</span>cd<span class="wrongLetter">e</span>"

 <style>
 .....
 .wrongLetter{
  background-color : #FF3100;
 }
 ......
 </style>

I could not find the way for using standard h:message in my case, so I solved it another way, by using h:outputText instead.

1) HashMap for custom validation messages :

@SuppressWarnings("serial")
@Scope(ScopeType.SESSION)
@Name("msgFactory")
public class WebMsg extends HashMap<String, String>{
     
     @Factory(value = "webmsg", autoCreate = true, scope = ScopeType.SESSION)
     public WebMsg getMessages() {
          return new WebMsg();
     }

     @Override
     public String get(Object key){
          String rez=super.get(key);
          if(rez!=null)remove(key);
          return rez;
     }
     
}

2) Put validation messages in webmsg instead of FacesMessages.instance().addToControl :

//FacesMessages.instance().addToControl("email", "message");
webmsg.put("email", "message");

3) Use h:outputText instead of h:message

                    <h:outputLabel for="email" value="Email" />
                    <h:inputText id="email" value="#{user.email}"/>
                    <h:outputText value="#{webmsg['email']}" escape="false"/>
