------------------------------------
Summary: MarkupContainer.streamChildren() not working with form?
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
Hi,
not sure if it is an error, but do me it seems a strange behavior. It seems to
me that after 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,
Helmut
