Hi Werner, I downloaded Castor 1.3.2, the problems I reported are not resolved.
1. all <field-handler/> defined in an included mapping file will not work, so all <filed-handler> have to defined in the top-level mapping file. 2. one <field-handler/>, just work for one <class/> Attached is my test files, just modify the path of StudentMap.xml in CastorTest.java , and run the CastorTest.java. > -----邮件原件----- > 发件人: Werner Guttmann [mailto:[email protected]] > 发送时间: 2011年3月10日 0:00 > 收件人: [email protected] > 抄送: 吕晓一 > 主题: Re: [castor-user] 答复: [castor-user] 答复: [castor-user] how to reuse > the field-handler defined in mapping file? > > Hi again, > > On 09.03.2011 12:02, 吕晓一 wrote: > > Hi Werner, > > > > Thanks for your great work! > > > > I just downloaded Castor 1.3.1 and found some problems, > > > > 1.
