When creating a selection list with the input taglib the order of elements gets 
mixtes up. this is a problem in case of e.g. Month selection list.

my workaround is: use two ArrayList object for values and lables:

input.tld change: 

<attribute>
	<name>optionLabels</name>
	<required>true</required>
	<rtexprvalue>true</rtexprvalue>
    </attribute>
    <attribute>
	<name>optionValues</name>
	<required>true</required>
	<rtexprvalue>true</rtexprvalue>
    </attribute>


code change:

    private ArrayList optionLabels ;        // the lables
    private ArrayList optionValues ;        // the submitted values
    public void setOptionValues(ArrayList x) {
        optionValues = x;
    }
    public void setOptionLabels(ArrayList x) {
        optionLabels = x;
    }

 in doStart():

 // changed:
            //
            if ( optionLabels.size() != optionValues.size() ){
                throw new JspException(
                            "option keys and option values must be of equal 
size");
            }
            HashMap options = new HashMap();
            ListIterator lIter = optionLabels.listIterator();
            int j = 0;

            while ( lIter.hasNext() ) {
                Object  key = (Object) lIter.next();
                Object  value = (Object)  optionValues.get( j);
                j++;
                options.put( key, value);

            }

            // actually print the <option> tags
            if (options.size() > 0 ) {
            //if (options != null) {
                Iterator i = optionLabels.iterator();
