Pedro Santos commented on WICKET-3512:
--------------------------------------
The main cause is also that TransparentWebMarkupContainer is resolving its
parent child components to their grandchildren even when its parent container
declared an homonymous component in markup, meaning that he is the one who
wants to render the component, and that it should not be resolved to
grandchildren. I'm preparing an patch fixing and exposing this bug with another
test case.

> Key: WICKET-3512
> URL: https://issues.apache.org/jira/browse/WICKET-3512
> Project: Wicket
> Issue Type: Bug
> Affects Versions: 1.5-RC2
> Reporter: Robin Shine
> Assignee: Pedro Santos
>
> Put below simple pages into a Wicket web application:
> TestPage1.html:
> <html>
> <head>
> <title>title</title>
> </head>
> <body>
> <div wicket:id="test1"></div>
> <wicket:child></wicket:child>
> </body>
> </html>
> TestPage1.java:
> package com.example.test;
> import org.apache.wicket.markup.html.WebPage;
> import org.apache.wicket.markup.html.basic.Label;
> public class TestPage1 extends WebPage {
> public TestPage1() {
> add(new Label("test1", "test1"));
> }
> }
> TestPage2.html:
> <wicket:extend>
> <wicket:enclosure child="test2">
> <div wicket:id="test2"></div>
> </wicket:enclosure>
> <wicket:child></wicket:child>
> </wicket:extend>
> TestPage2.java:
> package com.example.test;
> import org.apache.wicket.markup.html.basic.Label;
> public class TestPage2 extends TestPage1 {
>
> public TestPage2() {
> add(new Label("test2", "test2"));
> }
> }
> TestPage3.html:
> <wicket:extend>
> <wicket:enclosure child="test3">
> <div wicket:id="test3"></div>
> </wicket:enclosure>
> </wicket:extend>
> TestPage3.java:
> package com.example.test;
> import org.apache.wicket.markup.html.basic.Label;
> public class TestPage3 extends TestPage2 {
>
> public TestPage3() {
> add(new Label("test3", "test3"));
> }
> }
> Here TestPage3 extends TestPage2, and TestPage2 extends TestPage1. Both
> TestPage2.html and TestPage3.html contains a <wicket:enclosure> tag. Now
> mount TestPage3 and access it, below errors will be generated:
> Message: The component [Component id = test2] was rendered already. You can
> render it only once during a render phase. Class relative path:
> org.apache.wicket.markup.html.basic.Label:test2
> Root cause:
> org.apache.wicket.markup.MarkupException: The component [Component id =
> test2] was rendered already. You can render it only once during a render
> phase. Class relative path: org.apache.wicket.markup.html.basic.Label:test2
> at org.apache.wicket.Page.componentRendered(Page.java:299)
> at org.apache.wicket.Component.rendered(Component.java:2570)

> at org.apache.wicket.Component.render(Component.java:2301)

> This error won't occur if <wicket:enclosure> is removed from one of the page.
