Subject [jira] Created: (BEANUTILS-339) BeanUtilsBean.setProperty throws IllegalArgumentException if value is null
Date Fri, 20 Feb 2009 10:41:02 GMT
BeanUtilsBean.setProperty throws IllegalArgumentException if value is null
--------------------------------------------------------------------------

                 Key: BEANUTILS-339
                 URL: https://issues.apache.org/jira/browse/BEANUTILS-339
             Project: Commons BeanUtils
          Issue Type: Bug
          Components: Bean / Property Utils
    Affects Versions: 1.8.0-BETA
            Reporter: Alan Escreet
            Priority: Blocker
             Fix For: 1.8.0-BETA


Line 1003-1004 conflicts with API doc: "If null is passed into a property expecting a primitive
value, then this will be converted as if it were a null string."

Line 1003 only tests if the value is null and 1004 explicitly casts to a String. If a bean
has a field of any other type, i.e. java.util.Comparator, then this fails with:
{{java.lang.IllegalArgumentException: Cannot invoke <myBean>.setComparator on bean class
'class <myBean>' - argument type mismatch - had objects of type "java.lang.String" but
expected signature "java.util.Comparator"}}
