netui:sellect , optionsDataSource, and ordered data

Question

Presenting ordered data using <netui:select> with optionsDataSource is funky. It expects data in the optionsDataSource Map exactly backwards from what it "should".
Because of this, you cannot use a TreeMap to sort the display text, and pass it to <netui:select> since it expects the display text to be in the "values" part of the map instead of the "keys".
The only workaround I've found is to put your data in a TreeMap for sorting, then iterate through the keys and copy the sorted data into a LinkedHashMap (which preserves order) while swapping the keys and values.
For example, if you used TreeMap in the <netui:select> sample code below, it will present the list ordered by the HEX "submit values", not the text seen by the user.
public HashMap _hashMap = new HashMap();
protected void onCreate()
_hashMap.put("#ff3333", "red");
_hashMap.put("#3333ff", "blue");
_hashMap.put("#33ff33", "green");

Answer 1

This probably happens because the your actionForm.decoderModel has a value that is not present as one of the entry(key) in the hashMap. Are you modifying the values in the hashMap by any chance?
