Not sure, to be honest. Given that there's field mappings for 'error'
elements within separate class mappings, I would assume that this should
work.

Hi,
I've got a data model with errors (i.e. uncertainties rather than mistakes) at
several places. Each of these has a distinct Java class representing it, e.g.
PointError, AxisError etc. Up until now I've reflected this in the
corresponding XML format with tags <pointerror>, <axiserror> etc., but it would
be nice to be able to just use <error> and have the class determined by the
context in which the <error> tag occurs. For example,
<axis>
<point>
<pointerror ... />
</point>
<axiserror />
</axis>
would be nicer as
<axis>
<point>
<error ... />
</point>
<error />
</axis>
Is this possible? I imagine that a mapping file fragment like this might work:
<class name="Axis">
<map-to xml="axis" />
<field name="Points" type="Point" collection="sortedset">
<bind-xml name="point" node="element" />
</field>
<field name="Errors" type="AxisError" collection="sortedset">
<bind-xml name="error" node="element" />
</field>
</class>
<class name="Point">
<map-to xml="point" />
...
<field name="Errors" type="PointError" collection="sortedset">
<bind-xml name="error" node="element" />
</field>
</class>
(plus the error classes' mappings) where the crucial thing is that there are
two <bind-xml name="error" .../>s. Is this sort of thing supported in Castor or
will I have to do some sort of preprocessing if I want this to work?
As usual, apologies if I've just not found the right part of the user guide!
Thanks,
Andy
