SmartGWT TreeGrid field filter with SelectItem

Question

I am using SmartGwt 3.0, GWT 2.4.0 in IE9.

I have a smartgwt treeGrid in which i customize a field filter to be a SelectItem as follows:

...
TreeGridField field = new TreeGridField();

SelectItem selectItem = new SelectItem();
selectItem .setShowTitle(false);

LinkedHashMap<String, String> lmapKeyLabel = new LinkedHashMap<String, String>();

for(...) {
      lmapStatusLabel.put(key, "<b>"+label+"</b>");
}

selectItem.setValueMap(lmapKeyLabel);
field.setFilterEditorType(selectItem);
treeGrid.refreshFields();
...

The presented values on the SelectItem are the keys and not the labels. The same happens with a ComboBoxItem.

Has this happenned to someone? Am i doing something wrong?

Can anyone help me?

Thank you, mif
