Re: [jira] Resolved: (WICKET-1712) Inheritance inside a Container throws WicketRuntimeException
But if I implement this Window-like panel by extending Border I have no way to notify the collapse/expand events to the containing content . In my previous implementation , the AbstractPullDownPanel defines two methods invisible()/visible() for successor to override , if they want to handle the collapse / expand events. But if I implement it in Border , and place the expand / collapse link to the top of the Border . Because the border is added to the panel , I find no way to notify the expand/collapse events to its containing panel. I don't know how to gracefully solve this problem just like the AbstractPullDownPanel ... (define two methods for successor to override) Does anybody know how to accomplish it ?

To summarize :
I want to make a Widget , AbstractPullDownPanel , that I can

Any panel extends AbstractPullDownPanel will have a title bar , with

When the panel is collapsed , it will leave a title bar there.
The state of the panel (open / closed) is stored in WebSession

If it only contains an empty RadioGroup :
RadioGroup selectDeselectGroup = new RadioGroup(selectDeselectGroup);
Everything works fine , no matter the panel is collapsed or expanded ,
page reloading is ok
But if I add Radio(s) inside the RadioGroup , only when the panel is
expanded , page-reloading is ok.
If the panel is collapsed , page reloading will throw

You're visiting the children of the border, which traverses
only all its children recursively. As you add the border to
the panel, the border is a child of the panel, but not the
other way around.
As the name visitChildren implies, the visitor never goes
up to its parents.
Maybe you want
ExpandCollapseListener listener = ((ExpandCollapseListener)
findParent(ExpandCollapseListener.class));
or
getPage().visitChildren(ExpandCollapseListener.class, new IVisitor() { ... });
(For visitChildern(), you can supply a type of the
Components you want to visit directly)

Hi But MyPanel's HTML is like this : wicket:panel span wicket:id=border style=width:136px; // blah /span /wicket:panel According to the hierarchy , I have to new a PulldownBorder and add it to MyPanel , isn't it ? As to the onClick() , I change to Timo Rantalaiho's suggestion : ExpandCollapseListener listener = (ExpandCollapseListener) findParent(ExpandCollapseListener.class); if (listener != null) listener.setExpanded(expanded); And it worked !!!

Re: Inheritance inside a Container
Hi , after a few try and errors , I can conclude how the problem occurs In the ChildPanel , if my code is as follows : wicket:extend span wicket:id=selectDeselectGroup /span blah... /wicket:extend and code : RadioGroup selectDeselectGroup = new RadioGroup(selectDeselectGroup); add(selectDeselectGroup); Everything goes fine , no matter the Child Panel is collapsed / expanded , page-reloading is OK But , if I add something inside the CheckGroup : wicket:extend span wicket:id=selectDeselectGroup input type=radio wicket:id=selectAll/select all input type=radio wicket:id=deselectAll/clean /span /wicket:extend and code : RadioGroup selectDeselectGroup = new RadioGroup(selectDeselectGroup); add(selectDeselectGroup); Radio selectAll = new Radio(selectAll , new Model(Boolean.FALSE)); Radio deselectAll = new Radio(deselectAll , new Model(Boolean.FALSE)); selectDeselectGroup.add(selectAll); selectDeselectGroup.add(deselectAll); (Note , I haven't implement any AjaxEventBehavior(onclick) to the 2 radios) Here comes the problem : If the Child Panel is expanded , page reloading is OK. But... If the Child Panel is collapsed (folded /hidden) and do page reloading , it will throw exception : Root cause: org.apache.wicket.WicketRuntimeException: The component(s) below failed to render. A common problem is that you have added a component in code but forgot to reference it in the markup (thus the component will never be rendered). 1.

Re: Inheritance inside a Container
Hello ,
I had exactly the same problem , and solved by searching to this post.
Thanks a lot.
BUT , today , I have another problem...
Today , the ChildPanel can accept a new parameter : boolean defaultVisible
if true , the content will be shown;
if false , the content will be invisible , only the title bar is visible.
The title bar is defined in ParentPanel , containing a title label and a
expand/collapse ajax link (a toggle).
Here comes the problem.
In the ChildPanel , if I write :
setVisible(defaultVisible);
and if the defaultVisible is false , the whole panel , including ParentPanel
(including title bar) will be invisible;
This makes users unable to make it re-appear.
However , if I write code like this :
get(content).setVisible(defaultVisible);
(content is the WebMarkupContainer defined in ParentPanel returning
isTransparentResolver() TRUE)
It will throw WicketRuntimeException while
org.apache.wicket.Page.checkRendering
org.apache.wicket.WicketRuntimeException: The component(s) below failed to
render. A common problem is that you have added a component in code but
forgot to reference it in the markup (thus the component will never be
rendered).
How to solve it ?

You should do this:
WMC wmc = new WMC(childContainer) {
@override boolean isTransparentResolver() { return true; }
};
This is not a bug. If you do add() in the subclass's constructor, you
add to the page itself. Which is how the hierarchy is constructed. By
telling the WMC that it is a transparent resolver, you tell it to look
for children without attached markup in its siblings.

I'm using wicket1.3 to create a generic panel with the option to hide
everything inside when clicking an ajax-button. While the actual
hidingshowing works fine I'm having trouble with inheritance.
This example should show what I mean:
This is my generic super panel (no ajax stuff in it here to show the
essential problem). The idea is, that the childContainer is set to
Visible:false when the button is clicked. All of this should happen in
the
super class, so i don't have to care about it in the child class:
public class testSuperPanel extends Panel {
public testSuperPanel(String id) {
super(id);

}
}
The markup for testSuperPanel:
wicket:panel
div wicket:id=childContainer

/wicket:panel
This is a sample child panel:
public class testChildPanel extends testSuperPanel {
public testChildPanel(String id) {
super(id);
add(new Label(childLabel,Test!));
}
}
and the Markup:
wicket:extend
span wicket:id=childLabel/span
/wicket:extend
As you see, it should simply display Test inside a MarkupContainer
(which
could be hidden from the superClass). When i try to display this Panel
however I get an Exception stating that no code is added for the Label
childLabel!
This can be solved by adding the childLabel to the container in the
superClass, but thats obviously not the way it is meant to be:
public class testSuperPanel extends Panel {
public testSuperPanel(String id) {
super(id);
WebMarkupContainer wmc = new
WebMarkupContainer(childContainer);
wmc.add(new Label(childLabel,Test!));
add(wmc);
}
}
So, is this a wicket bug with inheritance inside containers or am I just
doing things the wrong way?
Thanks for your help!

Re: Inheritance inside a Container
Well , let me describe more detail
When the user enters the page , he can successfully show/hide the content
(ChildPanel) without problems.
The state is stored in wicket's session.
If the ChildPanel is open(expand/show) , and he reloads the page ,
everything works fine.
BUT...
If he close (collapse/hide) the ChildPanel , and reloads the page , the
runtimeException is thrown.
I don't know how to solve this problem...

add(new WebMarkupContainer(childContainer));
}
}
The markup for testSuperPanel:
wicket:panel
div wicket:id=childContainer
wicket:child/
/div
/wicket:panel
This is a sample child panel:
public class testChildPanel extends testSuperPanel {
public testChildPanel(String id) {
super(id);
add(new Label(childLabel,Test!));
}
}
and the Markup:
wicket:extend
span wicket:id=childLabel/span
/wicket:extend
As you see, it should simply display Test inside a MarkupContainer (which
could be hidden from the superClass). When i try to display this Panel
however I get an Exception stating that no code is added for the Label
childLabel!
This can be solved by adding the childLabel to the container in the
superClass, but thats obviously not the way it is meant to be:
public class testSuperPanel extends Panel {
public testSuperPanel(String id) {
super(id);
WebMarkupContainer wmc = new
WebMarkupContainer(childContainer);
wmc.add(new Label(childLabel,Test!));
add(wmc);
}
}
So, is this a wicket bug with inheritance inside containers or am I just
doing things the wrong way?
Thanks for your help!
best regards, Oli

Re: Inheritance inside a Container
In other words, what you should have done in the first place was
public class testChildPanel extends testSuperPanel {
public testChildPanel(String id) {
super(id);
get(childContainer).add(new Label(childLabel,Test!));
}
}
So that the label would have actually been attached to the
webmarkupcontainer instead of the panel.
However the solution Martijn provided is much more elegant since it
eliminates the need for subclasses to be aware of implementation
details in the parent class.

You should do this:
WMC wmc = new WMC(childContainer) {
@override boolean isTransparentResolver() { return true; }

This is not a bug. If you do add() in the subclass's constructor, you
add to the page itself. Which is how the hierarchy is constructed. By
telling the WMC that it is a transparent resolver, you tell it to look
for children without attached markup in its siblings.

Hi everyone,
my first mail to the list, i hope this wasn`t answered million times

I'm using wicket1.3 to create a generic panel with the option to hide
everything inside when clicking an ajax-button. While the actual
hidingshowing works fine I'm having trouble with inheritance.
This example should show what I mean:
This is my generic super panel (no ajax stuff in it here to show the
essential problem). The idea is, that the childContainer is set to
Visible:false when the button is clicked. All of this should happen in the
super class, so i don't have to care about it in the child class:
public class testSuperPanel extends Panel {
public testSuperPanel(String id) {
super(id);
add(new WebMarkupContainer(childContainer));
}
}
