getMemberList() on dimension with keys (UNX universe) DS1.3

Hello,

I have an unx universe with a COUNTRY dimension.

it has a Primary Key defined.

I'm trying to get a member list with:

DRP_COUNTRY.setItems(DS_COUNTRY_LIST.getMemberList("_g1wJeoj8EeONX6-WtGiC9g", MemberPresentation.INTERNAL_KEY, MemberDisplay.TEXT, 0));

but this returns only text values for key and dimension.

Brazil/Brazil instead of 37/Brazil

DRP_COUNTRY.getSelectedValue() and DRP_COUNTRY.getSelectedText() return the same Text value

I'v tried also with MemberPresentation.EXTERNAL_KEY and NONCOMPOUNDED with same result.

any idea?

The problem is that if I define a variable (prompt) with this dimension, it expects a KEY value, and I can't pass the selected value from the drop list.

Thank you.
