Re: Binding selected values from a ListView into a Mode
Hi
Yep I got it going. Prepopulating and the 'the base/fundamental' was a good
start that kinda helped in looking at other parts of the problem. Thanks for
the time
Cheers

Hi All,
I have a problem to deal with binding selected values into a model within a
ListView. I have tried to outline the approach and class definitions out
here. I hope I have been clear. Would appreciate your thoughts on the design
and approach i have taken so far. I guess am pretty close to it just one
hurdle.
public class MainVO{
private List userRoleList;
}
public class UserModuleRole{
private Role role;
private Module module;
private User user;
}
*Problem:*
1. I want to list the modules and the roles available for each module in a
list view.
2. Select a Role from each module for a user
3. Save - Will have the user linked to one or more modules with a role for
each.(only one role per module)
*Approach*
I used a ListView and rendered the list of modules and their respective
roles in a drop down. To render this List view these are the steps I took.
public class ModuleVO implements Serializable{
private Module module;
private List moduleRoles;
}
1. I get a Collection/List of ModuleVO via the service. The collection will
have a ModuleVO per module with the associated roles as a member.
2. I iterated the list and rendered the Module and render a DropDownChoice
3. End of which I get the following output in the list
*
Output from List view*:
Module Role
Module-A Role-1
Role-2
Module-B Role-3
Role-4
What I have not done and not clear is:
4. At this time I have not bound a Model to the dropdown and just used new
Model() for the Model argument of dropDownChoice.
I know that the selected values must eventually be in the MainVO's
List userRoleList property.
What is not very clear to me at this point is how to bind it ...so that when
the user saves the selected values are captured. I am sure this is possible
and should be elegant. Your thoughts and time will be of great value.

Instanciate the MainVO with a UserModuleRole for every Module and the
known user. The role
has only to be loaded if it's already assigned. That is the base.
If your listview is on a panel / form - give it the MainVO instance.
Set the MainVO.userRoleList to the ListView by using a
PropertyModel>.
In ListView.populateItem you get every single UserModuleRole. Render the
UserModuleRole to the
ListViewItem.
The DDC for the roles gets a PropertyModel pointing to the
UserModuleRole of the ListViewItem.
The selectable Roles have to be provided by a LoadableDetachableModel
calling your service.

Binding selected values from a ListView into a Mode
Hi All,
I have a problem to deal with binding selected values into a model within a
ListView. I have tried to outline the approach and class definitions out
here. I hope I have been clear. Would appreciate your thoughts on the design
