Karsten Winkler commented on WICKET-5777:
-----------------------------------------
*Test-Scenario:*
* use Wicket Quickstart with M4
* change HomePage.html (e.g. add a link) and wicket:head meta:
{code:title=HomePage.html}
<!DOCTYPE html>
<html xmlns:wicket="http://wicket.apache.org";>
<wicket:head>
<meta http-equiv="X-UA-Compatible" content="IE=10; IE=9; IE=8; IE=7;
IE=EDGE"/>
</wicket:head>
<body>
<a href="#" wicket:id="foo">a dynamic link</a>
</body>
</html>
{code}
* change HomePage.java e.g. add an AjaxLink (change from static to dynamic)
{code:title=HomePage.java|borderStyle=solid}
package com.mycompany;
import org.apache.wicket.ajax.AjaxRequestTarget;
import org.apache.wicket.ajax.markup.html.AjaxLink;
import org.apache.wicket.request.mapper.parameter.PageParameters;
import org.apache.wicket.markup.html.basic.Label;
import org.apache.wicket.markup.html.WebPage;
public class HomePage extends WebPage {
private static final long serialVersionUID = 1L;
public HomePage(final PageParameters parameters) {
super(parameters);
}
@Override
protected void onInitialize() {
super.onInitialize();
add(new AjaxLink<Void>("foo") {
@Override
public void onClick(AjaxRequestTarget
ajaxRequestTarget) {
}
});
}
}
{code}
* start application in Tomcat 7
* press CTRL-R on HomePage -> error
* repeat with with M3 -> no error
Thank you...
