[jira] Reopened: (BEANUTILS-294) BeanUtilsBean.setProperty() does
not support nested map
[ https://issues.apache.org/jira/browse/BEANUTILS-294?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Stephen Leung reopened BEANUTILS-294:
-------------------------------------
Just tried setting nested map property with BeanUtilsBean.setProperty() and it seemed it still doesn't support nested maps. The test case mentioned above (PropertyUtilsTestCase.testSetMappedMap()) works because it is using PropertyUtils, but not BeanUtils. If we replace PropertyUtils.setProperty() with BeanUtils.setProperty() in the unit test, then the unit test will fail.
It is important to make BeanUtils.setProperty() to support nested maps since it is used by Struts.

> Affects Versions: 1.8.0-BETA

> Priority: Critical

> I tried to call BeanUtilsBean.setProperty() with a DynaActionForm as the "bean" and "someMap(x)(y)" as the "name". In BeanUtilsBean.setProperty(), after the while loop at line 900, target became "null" and name became = "(y)". And consequently IllegalArgumentException is thrown at line 930 when setProperty() tried to getPropertyDescriptor() of a null bean. Specifically, the following is the stack trace. Could somebody look into it?
> Thanks.
