don't understand model behaviour for a form and a datatable

[puschteblume]

I have a DataTable in a Panel which creates a Subpanel by an AjaxRequest 
with a form in it. The form shows the double-clicked entry of a 
DataTable's row, where the objects parameters can be changed by pressing 
the save button. The form is constructed by a CompoundPropertyModel.


And now comes the magic I don't understand: If I press the save button 
the object in the table will immediately updated although the submit 
methods are empty.


How does this behavior work? How can I interupt this update if I have a 
problem on the backend?

Re: How to build a dynamic navigation bar

[puschteblume]

Here is my code that works for me. I put the navigation bar in a panel.

wicket:panel
   span wicket:id=mainNavList
 span wicket:id=navigationItem 
   a href=#
 span wicket:id=navigationLabel/span
   /a
 /span
   /span

/wicket:panel

And the java class looks like this:

public class MainMenuListView extends ListViewINavigationItem {

   private static final long serialVersionUID = 1L;
   protected static Logger logger = 
Logger.getLogger(MainMenuListView.class);
  
   public MainMenuListView(String id, ListINavigationItem dataList) {

   super(id, dataList);
   }
  
  
   @Override

   protected void populateItem(ListItem item) {
   INavigationItem navItem = (INavigationItem) item.getModelObject();
   ResourceModel rModel = new ResourceModel(navItem.getResourceKey());
   BookmarkablePageLink pageLink = new 
BookmarkablePageLink(navigationItem, navItem.getNavTargetClass());
   item.add(new BookmarkablePageLink(navigationItem, 
navItem.getNavTargetClass()).add(new Label(navigationLabel, rModel)));

   }

}

They need the same wicket:id yes, but that doesn't mean that they need the same 
text or targets. Just create as many links as you want/need, with whatever 
behaviour they need. Just make sure they all have the same id :)

Thanks for the quick reply.

Wouldn't this force all links to have the same wicket ids (linkid)?
I'd like to be able to have the line items look like this:

ul wicket:id=list
li # Link01 text here /li
li # Link02 text here /li
li # Link03 text here /li
/ul

Assuming this lil code

add( new ListView(list, linkList )
{
public void populateItem(ListItem item)
{
item.add( (Link)linkList );
}
});

You'd have the html look something like this

ul wicket:id=list
li # Link text here /li
/ul

Just remember to add whatever you want to the item, and not just use
add(...).

Emne: How to build a dynamic navigation bar


Hello, 
  
I want to be able to build a left-side dynamic navigation bar based on

user
permissions. For example, if the user does not have access to the Prices
page, I do not want to show the Prices link on the navigation bar. Also,
since the link will point to a Wicket page, it has to be a Wicket link. 

This is how I would like the NavBar to appear: 


div id=mainNav
ul
li Home /li
li Prices /li
li Contracts /li
li Products /li
li Transactions /li
/ul
/div

I tried using ListView, but I could not get it to work, as it forces the
wicket id of the line items to be all the same. 



Thanks in advance.

StyleSheetReference - what does href mean?

[puschteblume]

Hello

First of all .. thanks for this wonderful peace of software.

I don't understand what the generate reference in the stylesheet link 
mean. The generated output is:


head
link rel=stylesheet type=text/css 
href=resources/net.form105.web.base.page.login.LoginPage/LoginPage.css wicket:id=styleSheet/
/head

This works as it should.

In the LoginPage.class I defined following:

add(new StyleSheetReference(styleSheet, new 
ResourceReference(LoginPage.class, LoginPage.css)));


But what means the generated reference?

resources/net.form105.web.base.page.login.LoginPage/LoginPage.css

What is the resources folder? I can't find them?

Sorry for the stupid question. I don't have some html experience ...

Thanks Heiko
