Subject [jira] [Commented] (BEANUTILS-421) NullPointerException in BeanUtilsBean.setProperty
Date Wed, 30 Jan 2013 13:29:12 GMT

    [ https://issues.apache.org/jira/browse/BEANUTILS-421?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13566465#comment-13566465
] 

Maxim Kramarenko commented on BEANUTILS-421:
--------------------------------------------

To fix it please replace
type = ((IndexedPropertyDescriptor) descriptor).
                    getIndexedPropertyType();
with
type = descriptor.getPropertyType();
