I define a <field-handler>, it can be used in only one <class/> As already mentioned, this does not work (as intended) with Castor 1.3.1, and will be fixed in Castor 1.3.2 (due to be released within a few days).
Once Castor 1.3.2 will have been released, it will be possible to define a field handler once and use it multiple times. > 2. if the <field-handler> is defined in a mapping file, and this file > is included by another main mapping file, marshal the java bean will > throw exception. If this is till an issue with Castor 1.3.2, please file a bug report and attach a working test case so that we can reproduce this easily. Having said that, feel free to cross-check with the 1.3.2 snapshot release and report back.
