Re: facelets taglib for tomahawk and sandbox

Hi!

Please consider adding the following handler for the AliasBean to your
project:
(This is my first Tag-Handler, so I am not sure if there is a more
elegant way - at least the AliasBean works here now)

import com.sun.facelets.FaceletContext;
import com.sun.facelets.FaceletException;
import com.sun.facelets.tag.TagAttribute;
import com.sun.facelets.tag.TagHandler;
import com.sun.facelets.tag.jsf.ComponentConfig;
import org.apache.myfaces.custom.aliasbean.AliasBean;

import javax.el.ELException;
import javax.faces.FacesException;
import javax.faces.application.Application;
import javax.faces.component.UIComponent;
import javax.faces.webapp.UIComponentTag;
import java.io.IOException;

public class AliasBeanHandler extends TagHandler
{
    private TagAttribute valueAttr;
    private TagAttribute aliasAttr;

    public AliasBeanHandler(ComponentConfig tagConfig)
    {
        super(tagConfig);

        valueAttr = getRequiredAttribute("value");
        aliasAttr = getRequiredAttribute("alias");
    }


    public void apply(FaceletContext ctx, UIComponent parent) throws
IOException, FacesException, FaceletException, ELException
    {
        Application app = ctx.getFacesContext().getApplication();

        AliasBean aliasBean = new AliasBean();

        String value = valueAttr.getValue();
        if (UIComponentTag.isValueReference(value))
        {
            aliasBean.setValueBinding("value",
app.createValueBinding(valueAttr.getValue()));
        }
        else
        {
            aliasBean.setValue(value);
        }

        String alias = aliasAttr.getValue();
        if (UIComponentTag.isValueReference(alias))
        {
            aliasBean.setValueBinding("alias",
app.createValueBinding(aliasAttr.getValue()));
        }
        else
        {
            aliasBean.setAlias(alias);
        }

        parent.getChildren().add(aliasBean);
    }
}

Thanks!
Ciao,
