Question

How do I correctly create internationalized labels for my form components so that when displaying feedback messages an internationalized field name is displayed instead of the name of the field in the java code?

I’ve read this:

https://cwiki.apache.org/WICKET/everything-about-wicket-internationalization.html

as well as the documentation for wicket’s xhtml tags:

https://cwiki.apache.org/WICKET/wickets-xhtml-tags.html

<label wicket:for="name">
     <wicket:label>
         <wicket:message key="label.name"/>
     </wicket:label>
</label>
<input wicket:id="name" type="text" wicket:message="placeholder:label.name" />

This results in the following error:

Last cause: Expected close tag for '<wicket:label>' Possible attempt to embed 
component(s) '<wicket:message key="label.name"/>' in the body of this 
component which discards its body

If I replace the wicket:message with some arbitrary text it displays the text in any associated feedback messages.

(There’s a related jira issue: https://issues.apache.org/jira/browse/WICKET-3903 however I still do not understand what has been done to fix this and what I must do …)

Just found out there is a way to do this in java:

add(new TextField<String>("name").setRequired(true).setLabel(new Model<String>(getString("label.name"))));

Is it possible to somehow do this in a more comfortable way?

Answer 1

I just tested the following:

<form wicket:id="form">
        <label for="input"><wicket:message key="input">some input</wicket:message></label>
        <input wicket:id="input" type="text" name="input">
        <input type="submit" value="submit">
 </form>

And in the java class:

Form<HomePage> form = new Form<HomePage>("form"
                              , new CompoundPropertyModel<HomePage>(this));
    wmc.add(form);

    TextField textField = new TextField("input");
    textField.setRequired(true);
    form.add(textField);

In the property file I provided:

input=SomeInputField

This led to the following screen (if I leave the requiered field empty and press submit.

Is this what you are looking for?
