Hi all! I'm Rodrigo di Lorenzo Lopes and I'd like to do some contributions to commons apache project (despite my poor English Knowledge). So, I have one problem with BeanUtils.copyProperties: From a source, I have a bean partialy populated. From another source, I have the same bean with others informations. How can I merge these beans? My solutions is: verify an mustOverwrite method before each copyProperty call. See the patch in attachment. ;) Best Regards, Rodrigo
