if possible please explain little bit about

div with CSS float: etc. in the page template.


div with CSS float means, that you use the float: CSS attribute to 
layout the div elements, like this:


htmlbody
div style=background-color:red; float:left;width:30%left/div
div style=background-color:blue; float: right;width:30%right/div
div style=background-color:greencenter/div
/body/html

You can find more information about that here:

Problems with CheckGroup

[burnst...@burnstone.ch]

Hi all

I'm trying to use CheckGroup, but encounter some problems. First, my code:

class NameValueListViewT extends ParameterValueProvider? extends 
ListViewT {


U void displayItem(ListItemT listItem, ParameterValueProviderU 
parameter) {

...
ListU enumItems = new ArrayListU(parameter.getEnumCodes());
addMultiSelectPanelListItem(listItem, enumItems, labelModel, new 
PropertyModelCollectionU(parameter,

 valueList), parameter);
}

U void addMultiSelectPanelListItem(ListItemT listItem,
   ListU enumItems, IModelString labelModel,
   IModelCollectionU model,
   final ParameterValueProviderU parameter) {

  CheckGroupU comp = new CheckGroupU(value);
  comp.setType(parameter.getType());
  comp.setRequired(!parameter.isOptional());
  comp.setLabel(labelModel);

  ListViewU enumListView = new ListViewU(values, enumItems) {
 @Override
 protected void populateItem(ListItemU item) {
item.add(new CheckU(check, item.getModel()));
item.add(new Label(value,
   item.getDefaultModelObjectAsString()));
 }
  };
  enumListView.setReuseItems(true);
  comp.add(enumListView);

  // Add panel
  MultiCheckBoxPanelU panelMCB = new
   MultiCheckBoxPanelU(COMPONENT_ID, comp);
  listItem.add(panelMCB);
}
}

ParameterValueProvider has the mehtods {get,set}Value[List].

The html looks like this:
html xmlns:wicket
wicket:panel
   span wicket:id=value
  span wicket:id=values
 input type=checkbox wicket:id=check /
 span wicket:id=value/span
 br/
  /span
   /span
/wicket:panel
/html

So far, so good. Values are getting displayed and the correct check 
boxes are selected. However, when submitting the form, I get an exception:
