     [ https://issues.apache.org/jira/browse/WICKET-1491?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sergey Derugo updated WICKET-1491:
----------------------------------

    Description: 
1. Create ModalWindow and don't set property *content* , for example:
{code}
package test.demo.webcontrols.popup;

import org.apache.wicket.extensions.ajax.markup.html.modal.ModalWindow;

public class DialogMessage extends ModalWindow {
    public DialogMessage(String id) {
        super(id);

        setTitle("popups.notification.header");
        //setContent(new InformationMessageContent(getContentId()));
    }
}
{code}

2. Create instance of DialogMessage and call method *show* - exception is thrown: 
message - WicketMessage: Error creating page for modal dialog.

Using this exception it's impossible to understand what is wrong. Either exception message should be more detailed.
