Re Palette

[Nivedan Nadaraj <sh...@gmail.com>]

Hi All,

I have used the Palette successfully in another scenario where it was pretty
straightforward, in that the bean/pojo has a selectedItmes and
availableItems property on the bean. That was nice and clean and would like
to do the same in the scenario below. If someone has any ideas do let  me
know.

Will describe the POJOS and what I want to achive..

The Pojos:


public class RoleVO implements Serializable {

  private String roleName;
  //  .. Getters and setters
}

public class ModuleVO implements Serializable{

  private String moduleName;
  private List<RoleVO> selectedRoles;

  //  .. Getters and setters
}


public class ModuleRoleVO implements Serializable{

  private List<ModuleVO> selectedModules;    //Represents the user
associated modules and their roles

  private List<ModuleVO> availableModules; //The list of choices

}


Lets say the ModuleRoleVO.availableModules list contains the following
items/data:

Module-A and contains Role-A and Role-B

Module-B and contains Role-A2 and Role-A3

and Assuming that ModuleRoleVO.selectedModules list contains only one item

Module-A and it contains Role-A and Role-B


I currently build a Wiquery based Accordion control and each Panel of the
accordion uses the ModuleRoleVO.availableModules to render the
header/section name of the Accordion Panel.

So the Accordion would be rendered like this.

Module-A  --> Section 1 of accordion



Module-B--> Section 2 of accordion


Now within each of the accordion Panel I want to insert the Palette control
that should display the available roles and selected roles for the module *
linked* with the section.

like so

*Module-A*

    Available Roles                            Selected Roles

                                                        Role-A
    Role-B


*Module-B*

    Available Roles                            Selected Roles

    Role-A2
    Role-A3

I would like to achieve the above and maintain the selected choices in the
model across submits.


What I have achieved so far and my doubt...

I  got to the point where I render the accordion with the respective module
names and add the palette within it.

I provide the list of available roles for the module as a PropertyModel into
the Palette. I do the same, as in provide the selected roles by comparing
the module name in the list of selectedModules list and if found get the
list of roles and build a PropertyModel and pass it to the palette. However
all this happens manually at initialization of the Palette. Once I submit
the values the selected items of each Paletted is infered by me manually and
then I pass it to be persisted. After it persits, the Palette loses the
selected choices. The reason being its not bound properly with the Model. If
it can infer the values from the bean it would be right. But I am missing
something here or maybe I gott to apporach it differently.

A Snippet of the code that builds the listview for the Accordion and
initialization of the Palette.

ListView sectionListView = new ListView(Constants.ACCORDION_SECTION,
containerForm.getModelObject().getAvailableModules()){
            /**
             *
             */
            private static final long serialVersionUID = 1L;

            @Override
            protected void populateItem(ListItem listItem) {

                ModuleVO availableModuleVO =
((ModuleVO)listItem.getDefaultModelObject());

                Label sectionName = new
Label(Constants.ACCORDION_SECTION_NAME_LBL, availableModuleVO.getModule());
                listItem.setRenderBodyOnly(true);//Excludes excess tags on
the markup
                listItem.add(sectionName);

                String displayModule;
                ModuleVO selectedModuleVO = new ModuleVO();

                //Match the available Module name with the user associated
module list
                for(ModuleVO userModule :membershipModules){
                     displayModule =
UIHelper.getDisplayModuleName(userModule.getModule());
                    if(displayModule.equals(availableModuleVO.getModule())){
                        selectedModuleVO = userModule;
                        break;
                    }
                }

                Palette rolePalette =
initialiseRolePalette(containerForm,selectedModuleVO,availableModuleVO);
                listItem.add(rolePalette);
            }
        };

        moduleAccordion.add(sectionListView);
        appRoleForm.add(moduleAccordion);//Add the accordion to the form
        add(appRoleForm);
    }


   private Palette initialiseRolePalette(ContainerForm containerForm,
ModuleVO selectedModuleVO, ModuleVO availableModuleVO){

        CompoundPropertyModel<ModuleRoleVO> moduleRoleCPM =
(CompoundPropertyModel<ModuleRoleVO>)containerForm.getModel();
        IChoiceRenderer<String> renderer = new
ChoiceRenderer<String>("role", "role");
        PropertyModel<List<RoleVO>> availableRoleChoicesPM = new
PropertyModel<List<RoleVO>>(availableModuleVO,"role");
        PropertyModel<List<RoleVO>> selectedRolesPM = new
PropertyModel<List<RoleVO>>(selectedModuleVO,"role");
        return new Palette("role", selectedRolesPM, availableRoleChoicesPM,
renderer, 5, false);

    }

If someone around with an experience with a similar use case or identical
one please give me a yell.

Thanks for the time.

Regards
Niv

Hi 
Just wanted to make some corrections to the above snippet.

private Palette initialiseRolePalette(ContainerForm containerForm,
                                                ModuleVO selectedModuleVO,
                                               ModuleVO availableModuleVO){

IChoiceRenderer renderer = new ChoiceRenderer("roleName", "roleName");

PropertyModel> availableRoleChoicesPM = new PropertyModel>                   
                                                                                  
(availableModuleVO,"roleName");
PropertyModel> selectedRolesPM = new
                                                           
PropertyModel>(selectedModuleVO,"roleName");

return new Palette("role", selectedRolesPM, availableRoleChoicesPM,renderer,
5, false);

}
