[Wicket-user] conditional component rendering
I searched the lists and found one other question about if/else component rendering. It didn't really provide any examples, only suggestions to use Visibility flagging or a component factory to get swappable panels within a border. Can I see an example of this component factory? What I had initially planned is a panel/border component that will take a component and render it. It would take an instance of an interface like this:
public interface IAlternatable
{
public Component getAlternateComponent();
}
and render only the component that is returned from the interface. I tried a few combinitions of visibility flagging/heirarchy modifications, but I can't modify the heirarchy in onBeforeRender() by Wicket design and visibility hacks screwed with my AJAX updates. Are there any examples of selecting which component to render at runtime in an generic way. Case scenarios I can think of that I would like to implement this with would be:
A component that can display itself, or a No Items Selected panel based on it's selection model
A tab panel or similar that can update it's body content based on the selected tab. I saw a tab panel in the examples, but the tabs where hard-coded panels (panel1, panel2, panel3, etc). I'm looking for a generic, clean method to do something similar... with AJAX too.
Sorry if I missed something obvious...

There is no example about this in the Wicket Examples. The only thing I found is the Javadoc of WebRequest.getHttpServletRequest() that says this warning: WARNING: it is a bad idea to depend on the http servlet request directly. Please use the classes and methods that are exposed by Wicket (such as Session instead. Send an email to the mailing list in case it is not clear how to do things or you think you miss funcionality which causes you to depend on this directly.

Re: [Wicket-user] conditional component rendering
look at the way TabbedPanel works. it gets a list of any number of panels and then swaps them so the right panel i shown for the selected tab.as far as your interface goes you can do something like this:String componentId=altcomp;
Component c=getAlternateComponent(componentId);if (c!=null) { add(c);} else { add(new WebMarkupContainer(altcomp).setVisible(false));}and in markupspan wicket:id=altcompalternative component/span
since the markup is fixed you should change the interface to return a panel because not all components can be attached to a span tag.
public interface IAlternatable
{
public Panel getAlternateComponent(String componentId);
}this should get you started-Igor

What I had initially planned is a panel/border component that will take a component and render it. It would take an instance of an interface like this:
public interface IAlternatable
{
public Component getAlternateComponent();
}
and render only the component that is returned from the interface. I tried a few combinitions of visibility flagging/heirarchy modifications, but I can't modify the heirarchy in onBeforeRender() by Wicket design and visibility hacks screwed with my AJAX updates. Are there any examples of selecting which component to render at runtime in an generic way. Case scenarios I can think of that I would like to implement this with would be:
A component that can display itself, or a No Items Selected panel based on it's selection model
A tab panel or similar that can update it's body content based on the selected tab. I saw a tab panel in the examples, but the tabs where hard-coded panels (panel1, panel2, panel3, etc). I'm looking for a generic, clean method to do something similar... with AJAX too.
Sorry if I missed something obvious...

Re: [Wicket-user] drop down
If I guessed right as to what you are asking... Basically, when your
drop down has a value, you want to 'un-hide' another part of the page.
In your case a form. The most conventional way I know of is to override
the 'isVisible' method for the component you want to hide unhide. In
the code snippets I included below, I am toggling a section of the
entire page.
For the drop down:
final ListChoice properties = new ListChoice(property,
dao.listAll(Property.class));
For the 'div' tag around the rest of the page (I wanted to hide more
than just a form):
WebMarkupContainer locationArea = new WebMarkupContainer(locationArea)
{
public boolean isVisible()
{
return model.getProperty() != null;
}
};
Does that help you?
- Jason B.
PS: You could also have a listener on the ListChoice that calls
locaitonArea.setVisible(true/false)... or probably many many other ways
to accomplish the same thing.

Re: [Wicket-user] conditional component rendering
Thanks for the input, I have a couple of quick questions for you regarding this implementation:
wicket:panel
span wicket:id=currentCurrent Component/span
/wicket:panel
public class AlternatablePanel extends UserPanel
{
private static Log log = LogFactory.getLog(AlternatablePanel.class);
IAlternatable alternatable;
public static final String COMPONENT_ID = current;
public AlternatablePanel(String string, IAlternatable alternatable )
{
super(string);
this.alternatable = alternatable;
add( alternatable.getAlternateComponent( COMPONENT_ID ) );
}
@Override
protected void onBeforeRender()
{
replace( alternatable.getAlternateComponent( COMPONENT_ID ) );
super.onBeforeRender();
}
}
That is my initial attempt Panel that will try to render based on the the component returned from the IAlternatable interface:
public interface IAlternatable
{
public Panel getAlternateComponent( String id );
}
The problem I'm running into is that because I must pass the id through the interface, I must also construct the components from the interface method? Here's what I have right now:
add( seriesEditor = new AlternatablePanel( series.editor, new IAlternatable() {
public Panel getAlternateComponent(String id)
{
if ( blockEditor.getSelectedItem() != null )
{
return new SeriesEditPanel( id,
new PropertyModel( blockEditor, selectedItem.item ),
new PropertyModel( streetEditor, items),
EditAddressesPanel.this );
} else {
return new EmptyPanel( id, You must select a block on the left );
}
}
}) );
The reason for this is I need the id upon creation of the sub-panels. I can't specify them from the parent. Now I either have to concrete the IAlternatable with specific accessors for my sub-panels, or.. what I'd *like* to do is implement the interface directly:
public Panel getAlternateComponent()
{
if ( items.size() == 0 )
return EmptyPanel( this.getMarkupId(), There are no items to display );
else
return this;
}
But the problem here is the markupID. How can I get the proper markupID to the component at *construction* time, so that I don't have to construct the object from the interface method (it's actually not possible for me to do since I have a set of 4-5 dependant panels who's models are dependant on each other). What I'm looking to avoid is circumstances where I need to spend 10-15 lines of code to wire up an anonymous class to handle component-swapping while keeping each component accessible to the outside world (if that makes any sense).

look at the way TabbedPanel works. it gets a list of any number of panels and then swaps them so the right panel i shown for the selected tab.
as far as your interface goes you can do something like this:
String componentId=altcomp;
Component c=getAlternateComponent(componentId);
if (c!=null) {
add(c);
} else {
add(new WebMarkupContainer(altcomp).setVisible(false));
}
and in markup
span wicket:id=altcompalternative component/span
since the markup is fixed you should change the interface to return a panel because not all components can be attached to a span tag.
public interface IAlternatable
{
public Panel getAlternateComponent(String componentId);
}
this should get you started

I searched the lists and found one other question about if/else component rendering. It didn't really provide any examples, only suggestions to use Visibility flagging or a component factory to get swappable panels within a border. Can I see an example of this component factory? What I had initially planned is a panel/border component that will take a component and render it. It would take an instance of an interface like this:
public interface IAlternatable
{
public Component getAlternateComponent();
}
and render only the component that is returned from the interface. I tried a few combinitions of visibility flagging/heirarchy modifications, but I can't modify the heirarchy in onBeforeRender() by Wicket design and visibility hacks screwed with my AJAX updates. Are there any examples of selecting which component to render at runtime in an generic way. Case scenarios I can think of that I would like to implement this with would be:
A component that can display itself, or a No Items Selected panel based on it's selection model
A tab panel or similar that can update it's body content based on the selected tab. I saw a tab panel in the examples, but the tabs where hard-coded panels (panel1, panel2, panel3, etc). I'm looking for a generic, clean method to do something similar... with AJAX too.
Sorry if I missed something obvious...

Re: [Wicket-user] RadioGroup questions and possible markupid bug
First:Read the javadoc again:* The model object of the gorup is set to the model object of* the selected radio component or null if none selected.So the RadioGroup's model is the correct property model. What is incorrect is the model you set on the Radio components. The Radio component's model object is what will be put into the RadioGroup's model. Does that make sense?
Second:I think the markupid is incorrect because you are in constructor of some component and the full path is not yet available. You need to defer the call to getMarkupId() until render time because then the component hierarchy is complete. This should be fixed in
1.3 refactor.For now try this:label2.add(new AttributeModifier(for, true, new AbstractRadOnlyModel() { Object getObject(Component c) { return radio2.getMarkupId(); }}));-Igor

Re: [Wicket-user] conditional component rendering
you lost me.But the problem here is the markupID. How can I get the proper markupID to the component at *construction* time, so that I don't have to construct the object from the interface method (it's actually not possible for me to do since I have a set of 4-5 dependant panels who's models are dependant on each other). but you have the markup id. every component has it passed in to its constructor. What I'm looking to avoid is circumstances where I need to spend 10-15 lines of code to wire up an anonymous class to handle component-swapping while keeping each component accessible to the outside world (if that makes any sense). this makes no sense. you want to have two components, only one of them in the component hierarchy and the other one floating somewhere? this doesnt work. components have to be in the hierarchy where they belong. furthermore in wicket1.3 you will not be able to have a component outside of hierarchy because instead of add() you will pass in the parent into constructor.the interface that takes the id in acts as a factory.i guess you can try and better describe the usecase, maybe give a few specific examples because i am totally lost. A component that can display itself, or a No Items Selected panel based on it's selection model Looking at this doesnt really make sense. You are adding a specific component and then all of a sudden that component replaces itself with another one but yet somehow stays connected to the hierachy AND there is only placeholder for one component in the markup? this doesnt work. either the component replaces itself with another and is then out, or you have two placeholders in your markup, add both components all the time, hide one and show the other. another idea you might want to try is a border. the border can have inside it the alternate component, and can wrap the regular component. by default the alternate is not visible. then when some condition occurs the border shows the alternate and callse setBorderBodyVisible(false) on itself that will hide whatever components are inside the border. -Igor
