http://issues.apache.org/bugzilla/show_bug.cgi?id=37450 Summary: LazyList throws IndexOutOfBoundsException when trying to set a value out of list bounds Product: Commons Version: 3.1 Platform: PC OS/Version: Windows XP Status: UNCONFIRMED Severity: normal Priority: P2 Component: Collections AssignedTo: commons-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] This was discovered when using struts 1.2.7 with dynamic forms (Tomcat 5.0.24, jdk 1.4.2). The reset() method in the ActionForm used LazyList.decorate(). if(rooms==null) { rooms = new ArrayList(); roomPrefs.add("-"); roomPrefs = LazyList.decorate(roomPrefs, factory); } However after reset() I get the error below when it tries to initialize the ArrayList. IndexOutOfBoundsException -> Index: 1, Size: 1 java.lang.IndexOutOfBoundsException: Index: 1, Size: 1 at java.util.ArrayList.RangeCheck(ArrayList.java:507) at java.util.ArrayList.set(ArrayList.java:340) at org.apache.commons.collections.list.AbstractListDecorator.set(AbstractListDecorator.java:97) at org.apache.commons.beanutils.PropertyUtilsBean.setIndexedProperty(PropertyUtilsBean.java:1417) at org.apache.commons.beanutils.BeanUtilsBean.setProperty(BeanUtilsBean.java:1016) at org.apache.commons.beanutils.BeanUtilsBean.populate(BeanUtilsBean.java:811) at org.apache.commons.beanutils.BeanUtils.populate(BeanUtils.java:298) at org.apache.struts.util.RequestUtils.populate(RequestUtils.java:493) at org.apache.struts.action.RequestProcessor.processPopulate(RequestProcessor.java:805) at .... Possible Solution: For now I've created a class similar to LazyList and have overridden the set(object, element) method and it has worked. public Object set(int index, Object element) { int size = list.size(); // Grow the list if (index >= size) { for (int i = size; i <= index; i++) { list.add(null); } } return list.set(index, element); } I'm not sure if I'm using LazyList the right way but thought I'd bring it to your attention.
