Yes...it seems that multiple selects are not yet supported, but it is
very easy to write a component...just take the select component from
tapestry, look for "value" and the isOptionValueSelected method. I
changed the value to Set type and changed the
protected void processSubmission(FormSupport formSupport, String
elementName) {
String[] primaryKey= _request.getParameters(elementName);
if( primaryKey != null ) {
Set selectedValues= new HashSet();
for( String key : primaryKey ) {
selectedValues.add( _encoder.toValue( key ) );
} // for
try {
_validate.validate(selectedValues);
_value= selectedValues;
} catch (ValidationException ex) {
_tracker.recordError(this, ex.getMessage());
return;
}
} // if
}
method. Now I have a "multiple-select" component which takes a value
parameter as a set...and it works fine...
cheers

Hi,
AFAICS doesn't the select component support the attribute
"multiple", only the first selected option is set on the
value.
Is there some way to get this to work with support for "multiple"?
Thx && cheers,
Martin
