Hi Igor,
I changed the implemention of wicket-stuff-phonebook to suit my needs where
in i needed do disable the delete button if none selected and re-enable it.
I also successfully used AjaxCheckBox and updated the webmarkup container
containing buttons.
Now, in the same example app.
1. I am trying to add the checkgroupselector to select all the checkboxes
and I did the following.
HTML looks like this:
<form wicket:id="filter-form">
<input type="hidden" name="tracker" wicket:id="focus-tracker"/>
<divwicket:id="group">
<input type="checkbox" wicket:id="groupselector">check/uncheck
all</input>
<table wicket:id="users" cellspacing="0" cellpadding="2"
class="grid">[for
DataTable]</table>
</div>
<div wicket:id="focus-restore">[call to focus restore script]</div>
<div wicket:id="buttonContainer">
<input wicket:id="delete-selected" value="DELETE CHECKED CONTACTS"
type="submit"/>
</div>
</form>
and the relavent Java Code looks like this:
CheckGroup group=new CheckGroup("group");
form.add(group);
group.add(new CheckGroupSelector("groupselector"));
// create the data table
IColumn[] columns = createColumns(buttonContainer);
users = new DefaultDataTable("users", Arrays.asList(columns),
dataProvider, 10);
//users.addTopToolbar(new FilterToolbar(users, form,
dataProvider));
group.add(users);
Problem :
1. It does show checkgroup but checking/un-checking it does not affect the
check boxes under it. What am I doing wrong here?
2. Also, can you give a brief example of the navigator with submit links.
Thanks,
Rachit
