I have asked the question about support for IDREFs before, but got no reply so far. I went through the code and found that the support for IDREFS is there. It is enabled if you mark a field descriptor as multivalued. But there is no way to set this flag using a mapping file. So if you can modify the Castor code you need not flatten your xml.
Hope this helps.

I am trying to get IDREFS to work, but without any luck as I end up with a class cast exception when the code tries to generate the IDREFS. I have an object Size, which contains a list of SizeDescriptions. I am intending to flatten this (would rather not but that is not my decision). For example. <snip> <SIZE ID="101" key="1" sizeDescriptions="12 14"/> <SIZE-DESCRIPTION ID="12" size="101 info="stuff"/> <SIZE-DESCRIPTION ID="14" size="101 info="stuff"/> <snip> Am I trying to reach too far on this? Is this possible in the current version (using snaphot from cvs of 18th March 2002) Thanks Glen I am using the following mapping file: <!DOCTYPE mapping PUBLIC "-//EXOLAB/Castor Mapping DTD Version 1.0//EN" "http://castor.exolab.org/mapping.dtd";> <mapping> <!-- Mapping for Size --> <class name="exit41.mumi.persist.Size" identity="id"> <description>Size Reference Class</description> <map-to table="Sizes" xml="SIZE"/> <field name="id" type="integer" required="true"> <bind-xml name="key" node="attribute"/> </field> <field name="description" type="exit41.mumi.persist.SizeDescription" collection="arraylist" required="false"> <bind-xml name="sizeDescriptions" node="attribute" reference="true"/> </field> </class> <!-- Mapping for SizeDescription --> <class name="exit41.mumi.persist.SizeDescription" depends="exit41.mumi.persist.Size" identity="idref"> <description>NLS support for Sizes</description> <map-to table="NLSSizes" xml="SIZE-DESCRIPTION"/> <field name="idref" type="string" get-method="getIDREF"> <bind-xml name="ID" node="attribute"/> </field> <field name="size" type="exit41.mumi.persist.Size" required="true"> <bind-xml name="sizeID" node="attribute" reference="true"/> </field> </class> </mapping> Glen Edwards Elm Square Interactive/Exit41 Three Dundee Park Andover, MA 01810 978-933-7464 [EMAIL PROTECTED] ----------------------------------------------------------- If you wish to unsubscribe from this mailing, send mail to [EMAIL PROTECTED] with a subject of: unsubscribe castor-dev ----------------------------------------------------------- If you wish to unsubscribe from this mailing, send mail to [EMAIL PROTECTED] with a subject of: unsubscribe castor-dev
