Benedikt Ritter commented on BEANUTILS-400:
-------------------------------------------
Hi smildlzj,
the exception thrown indicates what is wrong:
{code}
java.lang.IllegalArgumentException: Indexed or mapped properties are not
supported on objects of type Map: mapProperty(mappedArray)
at
org.apache.commons.beanutils.PropertyUtilsBean.getPropertyOfMapBean(PropertyUtilsBean.java:813)
at
org.apache.commons.beanutils.PropertyUtilsBean.getNestedProperty(PropertyUtilsBean.java:764)
at
org.apache.commons.beanutils.PropertyUtilsBean.getProperty(PropertyUtilsBean.java:846)
at
org.apache.commons.beanutils.PropertyUtils.getProperty(PropertyUtils.java:426)
{code}
PropertyUtils does not support this kind of access on Maps (yet). If you want
you can create a SVN patch for this. We can then include it in the next
release. Because PropertyUtils produces a failure that tells users what is
wrong, this doesn't have the highest prio ;-)
Regards,
Benedikt
