Re: CheckGroup and ListView
QuickStart project added. BTW thanks for the instructions for creating the quick start. If any one else needs the instructions then they can be found at: http://www.jeremythomerson.com/blog/2008/11/wicket-quickstart-tutorial/#more-99 Well, I hope the quick start works for others too.

Re: CheckGroup and ListView
Well, I have tried using ListModel as following:
selectableValues = new ListViewSelectableValue(selectableValuesList, new
ListModelSelectableValue(list))
{
..
}
and then:
selectableValues.getModelObject().add(new
SelectableValue(newId, value
+ newId++));
without any success.
BTW, do I also need to set the model for the CheckGroup as following?
checkGroupSelectableValues = new
CheckGroupSelectableValue(selectedValues, new
CollectionModelSelectableValue(list));
I did not need to do this in my other application but in this application if
I don't do it then I get the model is null exception. I thought that when I
add the ListView Object to the CheckGroup object then the model object is
set for CheckGroup.
The bottom line is that I can not make this thing what ever I tried.
Please help. Thanks.

Re: CheckGroup and ListView

Re: CheckGroup and ListView
Well, I have tried removing and then adding the ListView to the CheckGroup, but that does not work either. I have tried to debug this as much as I could and I do see that there are the right values in the java objects of ListView and the wrapped list. To me it looks like that the code that creates the html or the script is not clearing the old values. But that is just my guess. But hopefully I am just not doing some thing right and some one would please point that out to me. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/CheckGroup-and-ListView-tp1886879p2133543.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: CheckGroup and ListView
I haven't looked at it in detail, but you shouldn't be doing that removeAll() and setList() stuff - it comes from a lack of using Models properly - which is the most common mistake I see in Wicket users. Instead, you should give the ListView constructor an instance of some IModelListSelectableValue. Then simply add your new selectable value to whatever list that model is getting it's data from. The ListView will auto-magically repaint everything correctly. -- Jeremy Thomerson http://www.wickettraining.com On Wed, May 5, 2010 at 3:59 PM, msalman mohammad_sal...@yahoo.com wrote: I have not heard anything on this one.

CheckGroup and ListView
I use a ListView to populate a CheckGroup with Check objects. It works fine
and all the check boxes are displayed properly. But when I try to add a new
check box to the ones previously added, I keep getting the new one along with
the previous ones in duplicate.
Here is my code. (I apologize for the format of the code)
protected void addCheckGroup(
ListSelectableValue list)
throws Exception
{
Object object = getDefaultModelObject();
checkGroupSelectableValues = new CheckGroupSelectableValue(selectedValues);
//checkGroupSelectableValues.add(new CheckGroupSelectors(groupSelector));
selectableValues = new ListViewSelectableValue(selections, list)
{
/**
*
*/
private static final long serialVersionUID = 1L;
@Override
protected void populateItem(
ListItemSelectableValue item)
{
item.add(new CheckSelectableValue(check, item.getModel()));
item.add(new Label(value, new
PropertyModelSelectableValue(item.getModel(), value)));
}
};
checkGroupSelectableValues.add(selectableValues);
selectableValues.setOutputMarkupPlaceholderTag(true);
checkGroupSelectableValues.setRenderBodyOnly(false);
checkGroupSelectableValues.setOutputMarkupPlaceholderTag(true);
add(checkGroupSelectableValues);
}
protected void addNewSelectableValue(
AjaxRequestTarget target)
throws Exception
{
ListSelectableValue list; // new list with the new SelectableValue added
selectableValues.removeAll(); // making sure to remove previous object
selectableValues.setList(list); // Adding the new list to the ListView
checkGroupSelectableValues.removeAll(); // making sure to remove previous
check boxes.
checkGroupSelectableValues.add(selectableValues);
target.addComponent(checkGroupSelectableValues);
}
I have tried different other methods but either I get the previous values in
duplicates or the new value does not show up.
I will appreciate help in solving this issue. Thanks
Mohammad
