> Key: WICKET-6743
> URL: https://issues.apache.org/jira/browse/WICKET-6743
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 8.6.1
> Environment: Tomcat 8.5
> Reporter: Helmut Lerch
> Priority: Major

> Hi,
> not sure if it is an error, but do me it seems a strange behavior. It seems to me that if there is a form in the a container the stream for streamChildren() stops.
> Code StreamChildrenPage.java
> {{public class StreamChildrenPage extends WebPage {}}{{public StreamChildrenPage() {}}
> WebMarkupContainer cont1 = new WebMarkupContainer("container1");
> cont1.add(new Label("label1", Model.of("Label 1")));
> Form<Void> form = new Form<Void>("form");
> cont1.add(form);
> form.add(new TextField<String>("text", Model.of("")));
> add(cont1);
> WebMarkupContainer cont2 = new WebMarkupContainer("container2");
> cont2.add(new Label("label2", Model.of("Label 2")));
> add(cont2);
> add(new Label("label3", Model.of("Label 3")));
> }
> @Override
> protected void onInitialize() {
> super.onInitialize();
> streamChildren().forEach(t ->
> { System.out.println(t.getClass() + " id: " + t.getId()); }
> );
> {{}}}
> Code StreamChildren.html:
> {{<!DOCTYPE html>}}
> {{<html xmlns:wicket="http://wicket.apache.org">}}
> {{<head>}}
> {{<meta charset="UTF-8">}}
> {{<meta name="viewport" content="width=device-width, initial-scale=1">}}
> {{</head>}}
> <body>
> <div wicket:id="container1">
> <div wicket:id="label1" ></div>
> <form wicket:id="form">
> <input wicket:id="text" />
> </form>
> </div>}}
> <div wicket:id="container2">
> <div wicket:id="label2" ></div>
> </div>
> <div wicket:id="label3" ></div
> </body>}}
> {{</html>}}
> Output:
> {{class org.apache.wicket.markup.html.WebMarkupContainer id: container1}}
> {{class org.apache.wicket.markup.html.basic.Label id: label1}}
> {{class org.apache.wicket.markup.html.form.Form id: form}}
> {{class org.apache.wicket.markup.html.form.TextField id: text}}
> If form (and TextField) are not added in java (and removed from html) the following output is obtained:
> {{class org.apache.wicket.markup.html.WebMarkupContainer id: container1}}
> {{class org.apache.wicket.markup.html.basic.Label id: label1}}
> {{class org.apache.wicket.markup.html.WebMarkupContainer id: container2}}
> {{class org.apache.wicket.markup.html.basic.Label id: label2}}
> {{class org.apache.wicket.markup.html.basic.Label id: label3}}
> {{class org.apache.wicket.markup.html.internal.HtmlHeaderContainer id: _header_}}
> Am I missing something?
> Thanks,
