Hi Tom,
your idea to parameterize Handlers sound reasoable to me. Can you please
search if there isn't an already existing issue for that. If there is
none please create one and propose the changes to mapping there. This
way we have a common place to discuss about the syntax and how the
parameters can be passed to the handler.
I'll respond to the gen.mapping problem at CASTOR-2041.
Regards
Ralf

Hi Ralf,
I will file a jira issue -- no problem.
In the meantime I figured out that I can get it working by adding the
castor-1.1.2.1-codegen.jar to the classpath (e.g. by adding it to the
lib dir). However, for some reason this only works once. When I run
gen.mapping a second time, it fails with the message
"java.lang.NoSuchFieldError: SORTEDMAP".
This seems to have something to do with the fact that generated source
for FieldMappingCollection type currently has a SORTEDMAP constant, but
this is not the case when the sources are re-generated.
I'll add this info to the jira issue, too.
The functionality I'm thinking about is a configurable xml type handler.
I need to marshall and unmarshall xml element values that have various
formats, like fixed width, padding with zeroes or spaces, left of right
aligned, different date formats, etc. The only solution I can find is to
implement a FieldHandler for each format, which would be silly. I was
thinking about adding a new element to the field element, that can be
configured; something like
<field name="myfield" type="string">
<handler class="com.fu.FixedWidth" arg="10"/>
</field>
or
<field name="myfield" type="string">
<handler class="com.fu.FixedWidth" arg="10, left-aligned"/>
</field>
The arg value can simply be passed to the handler's constructor, or
maybe some initialize method.
I think this is pretty similar to the sql parameterized type converters (?)
What do you think of it?
Cheers,
Tom

Hi Tom,
at the moment we only recreate mapping source files on demand. As far as
I recall we have not done that for a while now and it seams that we
broke that ant task with one of our refactorings since then. I guess
the
problem is related to moving of codegen into a separate modul but I will
check that myself. Could you please fill a new jira issue that
gen.mapping is broken as a reminder for me.
Would you mind to let us know what kind of feature you intend to add to
mapping?
Regards
Ralf
