James Carman commented on BEANUTILS-321:
----------------------------------------
By the way, this is mentioned in the API documentation (albeit in a somewhat
roundabout way). The BeanUtils class uses a PropertyUtilsBean:
http://commons.apache.org/beanutils/commons-beanutils-1.7.0/docs/api/org/apache/commons/beanutils/PropertyUtilsBean.html
"The name of the actual getter or setter method to be used is determined using
standard JavaBeans instrospection, so that (unless overridden by a BeanInfo
class, a property named "xyz" will have a getter method named getXyz() or (*for
boolean properties only*) isXyz(), and a setter method named setXyz()."
> [beanutils] wont recognize isXXX() properties returning Boolean Object

> Key: BEANUTILS-321
> URL: https://issues.apache.org/jira/browse/BEANUTILS-321
> Project: Commons BeanUtils
> Issue Type: New Feature
> Affects Versions: 1.7.0
> Reporter: thomas menzel
>
> it seems that an isXXX() style property returning an java.lang.Boolean Object
> is NOT recognized as the getter peoperty -- at least it wont copy it.
> Hence, the test case below will fail.
> I suggest to handle these props as well, as for a user of BeanUtils this
> was/is quite surprising to me -- and probably others.
> Thx
