Hi all,
I have a ComboBoxCellEditor whose items is decided after the user has selected
the corresponding element in the TableViewer. Say if I select element1, its
ComboBoxCellEditor should take "A" and "B" as its items, while if I select
element2, the items should be changed to "C" and "D".
For now, I'm giving the TableViewer a ComboBoxCellEditor with empty item
set. Then I listen to the selection change event and set the ComboBoxCellEditor's
items dynamicly. The problem is that it cannot store the original selected
item when I click into the cell. For instance, suppose the ComboBoxCellEditor
holds "A" for element1, when I click into the ComboBoxCellEditor, it will
take "A" and "B" as its items, but the "A" item will not be selected anymore,
the ComboBoxCellEditor becomes empty.
I was thinking ComboBoxCellEditor's setValue method should work, so I put
the index of the selected item(for "A" is 0) in, but it didn't make any good.
I also tried to created a brand new ComboBoxCellEditor(or the whole CellEditor[]
for the TableViewer) when the different element is selected. But it seems
like that one TableViewer's CellEditors can be set only once.
I don't know if I made myself clear. Is there any suggestion on this? Thanks
a lot!
Allen

If you have done the following:
comboBoxCellEditor.setItems({"A","B"});
comboBoxCellEditor.setValue(new Integer(0));
then your ComboBoxCellEditor will contain "A" and B" items. The "A" item
will be selected.
I suppose that you have set some other values ("","A","B", for instance)
to the setItems method or you use incorrect parameter for the setValue
method.
