Obtain combo box key from its value [message #1468881]

Hello! I'm current using SWT's Combo Box by setting key/value pairs as follows:

combo.add(<key>);
combo.setData(<key>,<value>);

When saving, the value is correctly saved into the database.
However, how do I do the "reverse" when editing a record and when I need to get the key from the value?
Note: My combo box is already populated with the key/pair values.

You can achieve this as below :
Map map = new HashMap();
map.put("key", "value");
combo.setData(map);
From combo.getData() call you can get the map object and the corresponding key/value pair back.
