How can i change lang attribute in html markup tag?

Hello,

i'm new to wicket and the mailing list. I already checked the search 
machines but didn't found anything.

i have to migrate a jsp. In the jsp there is a html tag like this:
<html xmlns="http://www.w3.org/1999/xhtml" 
xmlns:wicket="http://wicket.apache.org/dtds.data/wicket-xhtml1.4-strict.dtd" 
lang="${prefLang}" xml:lang="${prefLang}">

The ${prefLang} was an attribute from the session scope. I already saw that 
wicket provides a language in session to.

Now my question: What is the wicket way for accessing the session locale and 
provide it in the markup (for lang attribute)?

Thanks for helping me.
Mike

Great Martin. Thanks alot it works as expected.

My solution:
LocalizedHtmlTag.java
import org.apache.wicket.behavior.SimpleAttributeModifier;
import org.apache.wicket.markup.html.WebMarkupContainer;

public class LocalizedHtmlTag extends WebMarkupContainer {

     public LocalizedHtmlTag(String id) {
         super(id);
         String language = getSession().getLocale().getLanguage();
         add(new SimpleAttributeModifier("lang", language));
         add(new SimpleAttributeModifier("xml:lang", language));
     }

     @Override
     public boolean isTransparentResolver() {
         return true;
     }
}

MyPage.java
public class MyPage extends WebPage {

     public MyPage() {
         add(new LocalizedHtmlTag("html"));
     }
}

MyPage.html
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html wicket:id="html" xmlns="http://www.w3.org/1999/xhtml" 
xmlns:wicket="http://wicket.apache.org/dtds.data/wicket-xhtml1.4-strict.dtd">
</html>

Yes, sorry.
You need to override
#isTransparentResolver()

WebMarkupContainer htmlTag = new WebMarkupContainer("html") {
        public boolean isTransparentResolver()
{
return true;
}
};

But i couldn't find

WebMarkupContainer.setTransparentResolver

There is only a Border.setTransparentResolver in wicket 1.4.15

Try with :

in .html:
<html wicket:id="html">
....

in .java:
WebMarkupContainer htmlTag = new WebMarkupContainer("html");
htmlTag.add(new SimpleAttributeModifier("lang",
getSession().getLocale().toString());
htmlTag.setTransparentResolver(true); // check the javadoc of this method

With further investigation i found a hint on using an IMarkupFilter.

Is there an example with this for my problem?

Thanks
Mike
