How to get the selected value from a <select cam-choices> ?>

Hi guys,

In my embedded form, I previously loaded the select input with a: Map<Integer, String> approvedRevisionsMap object (from a JavaDelegate class, serializing the approvedRevisionsMap object to json).

  <select cam-variable-name="revisions"

After I pick a value from the select in the form,
I can only get the index of the selected value by doing:
(that would be the key of a <key,value> pair)

I need the selected value itself, not the index, how do I get it ?
(I want the value from a <key,value> pair)

Hope I was clear,
thanks in advance.
