Dealing with Jlist

I have one frame in which i have a Jlist box.
the AllGroupList populates some user name dynamically.
Now i have a edit button for that Jlist box.
The edit button will open a dialog.
The dialog will have two list box and search button to search new users so we can add users.
1) AvailableGrp_list
2) currentgrpmembership_listbox

currentgrpmembership_listbox is filled up when i call the dialog(by passing frame list model)

AvailableGrp_list is filled up by the search criteria

My problem is that when ever i add an element in the dialog from AvailableGrp_list to currentgrpmembership_listbox it gets added but at the same time the element also gets added in parent frame list AllGroupList.

why is it so?
Is this the correct way to pass a list from one frame to other dialog if we need the dialog to be initialized by a list from calling frame?

Once the user selects the users to be added, i want to load my AllGroupList(present in frame) with currentgrpmembership_listbox (which the user will upadte from dialog) can some one help in that also?

Hi Ray,

it seems to me that you need to create a second model for currentgrpmembership_listbox. You share pass your model to your target list, which means it is beeing shared by the listbox in the frame.

Kind Regards

It is sorta covered in the JavaRanch Style Guide.
