Hi, Can the following code of the OptionsTag.doEndTag() method // 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, match); } Be changed to this: // 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)); } Why the cast? Why not call the toString() method (if it is a string it returns directly the this) This is because i have options where the values are a Integer array. So i want to set a Integer Array as the values. But the i get a classcast exception because struts wants it to be a String. Now i must do this (made very simple): String[] getValues() { Integer[] aiValues = database.getValues(); String[] asValues = new String[aiValues.length]; for(int i = aiValues.length; --i >= 0;) { asValues[i] = aiValues[i].toString(); } return asValues; } I find this very annoying.
