Yes this i already reported twice!
Please fix this.
I my self have fixed this by not doing a cast but calling toString() in the
OptionsTag.doEndTag()
// Construct iterators for the values and labels collections
Iterator valuesIterator = getIterator(name, property);
Iterator labelsIterator = null;
if ((labelName == null) && (labelProperty == null))
labelsIterator = getIterator(name, property); // Same coll.
else
labelsIterator = getIterator(labelName, labelProperty);
// Render the options tags for each element of the values coll.
while (valuesIterator.hasNext())
{
String value = valuesIterator.next().toString();
String label = value;
if (labelsIterator.hasNext())
label = labelsIterator.next().toString();
addOption(sb, value, label, selectTag.isMatched(value));
}
