Please take a look at http://jakarta.apache.org/commons/beanutils/apidocs/org/apache/commons/beanutils/BeanUtilsBean.html#describe(java.lang.Object) The "map" contains the toString converted property values. ConvertUtils.convert(String[]) is called and it returns the first value in the array. > BeanUtils.populate(searchForm, map); > > At the first line, document contains a selectedUserGroups property that is a > String[] array with five values. > At the third line, map references a HashMap that contains a key for > selectedUserGroups that contains a String[] with one value. > > How do I get all the values? Any help would be appreciated.
