ComboBox - table datasource when using option caption

I am populating the ComboBox with a datasource table (value int, visible_value String).

But when I do form.setIemDataSource() the value does not show up.
Then, when I do not use the visible_value then it populates on selecting a row.
So with visible_value the combobox is not populating.

cb = new ComboBox("tit");
cb.setItemCaption(value); // this works ok

And I try this:
cb = new ComboBox("tit");
cb.setItemCaption(value, (String) visible_value); // this does not work

Question: Is there a programatic way to select a item from combobox when using the visible_value ?

The table I have is myvideo ( value int, visible_value String):

value visible_value
1 GO_TO_MOVIE
2 GET_DVD
3 RENT_VIDEO

Create a simple form, a table and ComboBox to recreate this. Have a split panel with top panel showing form and bottom panel showing the table list. When you select a row in list panel the top form panel shows the combobox.
