Alexandru Sirbu commented on BEANUTILS-97: ------------------------------------------ (In reply to comment #18) If you have a Bean with a property foo:List<foo1> with 4 Methods getFoo() getFoo(index) setFoo() setFoo(index, newFoo1) jdk 1.5_06 will not return an IndexedPropertyDescriptor so the method getFoo(index) will never be called To fix this I observed that if you made the change that Niall Pemberton (comment #18) has exposed, in the PropertyUtilsBean class, then you can write only 3 methods getFoo() getFoo(index) setFoo(index,newFoo1) without getting an error.After that jdk1.5_06 will recognize your property like an indexedProperty and getFoo(index) will be called to fill in your form after a submit (Struts). > [beanutils] Problems on indexed property with JDK 1.4 > ----------------------------------------------------- > > Key: BEANUTILS-97 > URL: http://issues.apache.org/jira/browse/BEANUTILS-97 > Project: Commons BeanUtils > Type: Bug > Versions: 1.6 Final > Environment: Operating System: other > Platform: Other > Reporter: Franco Caponi > Attachments: BeanUtilsBeanIndexed.txt, IndexedBean.java, IndexedBean.java, > IndexedPropertyTestCase.java, IndexedTestBean.java, PropertyUtilsBeanJDK.txt, > PropertyUtilsTestBean.java, PropertyUtilsTestBean.java, butc.diff > > I'm experiencing problems porting an existing struts 1.1 application on JDK > 1.4. > Debugging the code, i have seen that the problem occur in getIndexedProperty, > because on jdk 1.3.1_02 return an instance of IndexedPropertyDescriptor while > in jdk 1.4.1_02 not! > To use indexed property on struts, whe declare 2 methods on the ActionForm: > one > that return the entire list and one that return an indexed element > A simple class that reproduce the problem is: > public class FooForm extends ValidatorForm { > protected List childs = new ArrayList(0); > > ... > } > public List getChilds() { > return childs; > } > public ChildsBean getChilds(int index) { > if (index + 1 > childs.size()) { > for (int i = childs.size(); i < index + 1; i++) { > childs.add(new ChildsBean()); > } > } > return (ChildsBean) childs.get(index); > } > > .... > } > > and the problem occur when i preload the forms values using a code like this > for (int j = 0; j < newChilds.size(); j++) { > BeanUtils.copyProperties(PropertyUtils.getIndexedProperty > (valBean,"childs",j), newChilds.get(j)); > } -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
