<objectsToAttach name="value" eType="org.eclipse.jem.java:ArrayType
java:/java.lang#int[]" unsettable="true" xmi:id="_eStructuralFeatures"
xsi:type="ecore:EReference">
<eAnnotations
cellEditorClassname=" org.eclipse.ve.java.core/org.eclipse.ve.internal.java.core.B eanFeatureEditor:jp.co.hitachi.yokohama.dtv.osdui.ValueEdito r "
entryExpandable="false"

The constructor for that class reauiqres two arguments not one:
org.eclipse.ve.internal.java.core.BeanFeatureEditor.BeanFeat ureEditor(JavaHe
lpers, Composite)
Could you attach a working sample? I think your problems may come from
elsewhere
When does this exception happens? When trying to edit a property in the
properties view?
Did you try to follow the examples there :
