Multi Selection JTable + Combobox (celleditor) + Click

Question

I have a table that accepts multi selection. On this jtable I add a column that I add a combobox like this:

public void setPriorityEditor(final String columnName) {
        final TableColumn col = ((BasicTableModel) table.getModel())
            .findTableColumn(columnName);
        col.setCellEditor(new PriorityComboBoxEditor());
    }

I would like to implement a new feature: to can update several field using a combobox which is part of my selection. http://imageshack.us/photo/my-images/40/qyks.png/ My probleme begin when i want to select a row wich part in my selection avec select several row, selection is refresh and i have now just one row selected. Is it possible?

Summary : Try to update severals columns with multi selection. Rows contain a column with a combobox. Select severals rows and use a combobox(which is part of selected rows) for update all the rows specific column with the value of combobox.

Regards guys.

Hi, appreciate English might not be your first language, but your question is very hard to understand. Could you update/clarify what you're asking? thanks.

Yes, but doesn't it make more sense to only have 1 combo-box somewhere else in your application instead of duplicating it for each row? that would simplify things for you. — BlackBox
Yes but user can use single line combo box too. I can't change basic design. — MatDev8
First thing : I just want to disable clear selection when i select a row wich part of my multi selection. i search in jTable methode but i don't found... — MatDev8

So i change code in changeSelection() methode like this:

if (extend) {
            super.changeSelection(rowIndex, columnIndex, toggle, extend);
            listTest = new ArrayList<Object>();
            for (int e : modelTable.getToolTipsJTable().getSelectedRows()) {
                listTest.add(e);
            }
            isExtend = true;
        } else {
            // super.changeSelection(rowIndex, columnIndex, toggle, extend);
            if (modelTable.getToolTipsJTable().getSelectedRows().length > 1) {
                listTest = new ArrayList<Object>();
                for (int e : modelTable.getToolTipsJTable()
                    .getSelectedRows()) {
                    listTest.add(e);
                }
                isExtend = true;
            }
            if (isExtend) {
                boolean isSame = false;
                for (Object i : listTest) {
                    if (((Integer) i).intValue() == rowIndex) {
                        isSame = true;
                    }
                }
                if (!isSame) {
                    isExtend = false;
                    super.changeSelection(rowIndex, columnIndex, toggle,
                        extend);
                }
            } else {
                super
                    .changeSelection(rowIndex, columnIndex, toggle, extend);
            }
        }

It's just for analyse, forgot cleanliness and performance :D If you need more informations add comment.
