Helmut Lerch updated WICKET-6743:
---------------------------------
Description:
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,
Helmut
