Show value for key in table

Question

Hello,
i have a table in a view that shows data that comes from a aRFC
model from the R/3 backend.
So far so good, the values shown are the same as in the backend.
Now i have the problem that two colums in this table contain only
keys (one character, represented as String).
I want to show the right values for this keys in the table, so i created
two simple types that contain the enumerations for these two columns.
The problem is, that i can not change the type of these two elements
in the Context of the view controller, because they are mapped from
the model and can not be altered.
Is there a "best practice" approach to the topic of getting values for
given keys from the backend?

Hello Armin,
yes you can change the type of your with something like this:
// get Mofiable type of your model attribute
ISimpleTypeModifiable statiType =               wdThis.wdGetAPI().getContext().getModifiableTypeOf(
     "YourModelNode.YourModelNode.YourModelAttribute");
// Set valid values for this data type
IModifiableSimpleValueSet statiValues =statiType.getSVServices().getModifiableSimpleValueSet();
statiValues.clear();
      for (int i = 0; i < yourValues.size(); i++) {
          //set key value pairs
          String statusText = yourValues.get(i);
         statiValues.put(i, statusText);
Hope it helps, regards
