No -- changing it to a list makes no difference whatsoever:
package problem;
import org.apache.log4j.Logger;
import org.apache.struts.action.ActionForm;
import java.util.ArrayList;
import java.util.List;
public class ProblemBean extends ActionForm {
final private static int ENTRY_ROW_COUNT = 2;
public ProblemBean() {
log.info( "initializing entries" );
entries = new ArrayList();
// Create some entries for the form
for (int ndx = 0 ; ndx < ENTRY_ROW_COUNT; ndx ++) {
ProblemItem a = new ProblemItem();
a.setInteger_value( new Integer(ndx));
entries.add( a );
}
}
private String working_perfectly = "A Value";
public String getWorking_perfectly() {
log.info( "getWorking_perfectly" );
return working_perfectly;
}
public void setWorking_perfectly( String working_perfectly ) {
log.info( "setWorking_perfectly to '" + working_perfectly + "'");
this.working_perfectly = working_perfectly;
}
private List entries;
public ProblemItem[] getEntries() {
log.info( "getEntries" );
ProblemItem[] result = new ProblemItem[entries.size()];
for (int ndx = 0; ndx < entries.size(); ndx++)
result[ndx] = (ProblemItem)entries.get( ndx );
return result;
}
public void setEntries( List entries ) {
log.info( "setEntries" );
this.entries = entries;
}
public static class ProblemItem extends ActionForm {
// Used so that each item can have a unique value.
private static Integer incrementing = new Integer( 0 );
public ProblemItem() {
this.integer_value = incrementing;
incrementing = new Integer( incrementing.intValue() + 1 );
}
private Integer integer_value;
public Integer getInteger_value() {
log.info( "getInteger_value" );
return integer_value;
}
public void setInteger_value( Integer iValue ) {
log.info( "setInteger_value to " + iValue );
this.integer_value = iValue;
}
private static Logger log = Logger.getLogger( ProblemItem.class );
}
private static Logger log = Logger.getLogger( ProblemBean.class );
}
