there seems to be a bug in the merge function of the schema2beans.jar on this site:

http://schema2beans.netbeans.org/files/documents/117/538/schema2beans-4.2.0.zip

when I'm merging two graphs with the mergeUpdate method, I do not receive any
PropertyChangeEvents when Attributes are changing.

Steps to reproduce:

generate binding classes with GenBeans for the jasperreports dtd:

http://jasperreports.sourceforge.net/dtds/jasperreport.dtd

create two report files that differ in one attribute:
8<--------------file1.jrxml--------------->8
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE jasperReport PUBLIC "-//JasperReports//DTD Report Design//EN"
"http://jasperreports.sourceforge.net/dtds/jasperreport.dtd">
<jasperReport bottomMargin="30" columnWidth="555" isFloatColumnFooter="true"
leftMargin="20" name="TableReport" pageHeight="842" pageWidth="595"
rightMargin="20" topMargin="30">
 <style fontName="Arial" fontSize="10" isBold="false" isDefault="true"
isItalic="false" isPdfEmbedded="false" isStrikeThrough="false"
isUnderline="false" name="Arial" pdfEncoding="Cp1252" pdfFontName="Helvetica"/>

8<----------------------------->8
write a test class:
JasperReport report = JasperReport.createGraph(new File("file1.xml"));
final PropertyChangeListener listen = new PropertyChangeListener() {
      public void propertyChange(PropertyChangeEvent evt) {
            System.out.println("event "+evt.getPropertyName());
      }
};
jasperReport.addPropertyChangeListener(listen);
JasperReport report2 = JasperReport.createGraph(new File("file2.xml"));
report.merge(report2,BaseBean.MERGE_UPDATE);

expected behaviour:

event /JasperReport/Title/Band:Height

observed behaviour:

I only receive events when Elements are updated.
