Internationalized Page Properties in Tapestry 4.1.2

The tapestry application login page has a property that stores a password that the user enters, which is then compared to a value from the database. If the user enters a password with multibyte characters, for example:

áéíóú

... checking the return value of getPassword () (an abstract method for the corresponding property) gives:

áéíóú

Clearly this is incorrectly encoded. Nevertheless, Firebug reports that the page is submitted in UTF-8, so, presumably, the request to submit the form will also be encoded in UTF-8. Checking the value coming from the database leads to the correct row, so it will not be a problem encoding the OS or IDE. I did not override the default value for Tapestry for org.apache.tapestry.output-encoding in the .application file, and the Tapestry 4 documentation indicates that the default value for the property is UTF-8.

So why does Tapestry seem like it encodes an encoding when setting a property?

The appropriate code should be:

login.html

<html jwcid="@Shell" doctype='html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"' ...>
    <body jwcid="@Body">
        ...
        <form jwcid="@Form" listener="listener:attemptLogin" ...>
            ...
            <input jwcid="password"/>
            ...
        </form>
        ...
     </body>
</html>

Login.page

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE page-specification
    PUBLIC "-//Apache Software Foundation//Tapestry Specification 4.0//EN"
    "http://jakarta.apache.org/tapestry/dtd/Tapestry_4_0.dtd">

<page-specification class="mycode.Login">
    ...
    <property name="password" />
    ...
    <component id="password" type="TextField">
        <binding name="value" value="password"/>
        <binding name="hidden" value="true"/>
        ...
    </component>
    ...
</page-specification>

Login.java

...
public abstract class Login extends BasePage {
    ...
    public abstract String getPassword();
    ...
    public void attemptLogin() {
        // At this point, inspecting getPassword() returns
        // the incorrectly encoded String.
    }
    ...
}
