Kodo extensions for embedded fields

Question

Hi,
I have the following situation: having input source, i generate persistent
classes and basic metadata for them. Then mapping tool creates a schema
and adds mapping information to this metadata as well.
Some of entities are marked embedded, but now i generate metadata for it
in a separate file. The problem is, that i want to specify externalization
extensions for these embedded entities, but Mapping tool does not transfer
this information into updated metadata files:
Assume there is an entity Trade, that has stateModel entity. stateModel is
embedded into trade. State model contains several enumeration attributes,
that have externalization extensions defined, to allow proper persisting/
loading from primitive attributes. Here is an excerpt from metadata for
state model after mapping tool has been run:
<?xml version="1.0" encoding="UTF-8"?>
<jdo>
<package name="com.bear.fi.tradehub.domain.trade">
<class name="TradeStateModelJDO">
<extension vendor-name="kodo" key="jdbc-class-ind-name"
value="none"/>
<extension vendor-name="kodo" key="jdbc-class-map"
value="none"/>
<field name="allocationStatus"
persistence-modifier="persistent">
<extension vendor-name="kodo" key="externalizer"
value="getByName"/>
<extension vendor-name="kodo" key="factory"
value="getByCode"/>
<extension vendor-name="kodo" key="jdbc-field-map"
value="none"/>
<extension vendor-name="kodo" key="jdbc-size" value="1"/>
</field>
</class>
</package>
</jdo>
However, the metadata for Trade itself (field stateModel) looks like:
<field name="state" embedded="true">
<extension vendor-name="kodo" key="jdbc-field-map"
value="embedded">
<extension vendor-name="kodo" key="allocationStatus">
<extension vendor-name="kodo" key="jdbc-field-map"
value="blob">
<extension vendor-name="kodo" key="column"
value="ALLOCATIONSTATUS"/>
</extension>
</extension>
i.e. field type is blob, not CHAR or INTEGER as the return type of
externalizer method is.
Is there any way to force Mapping tool to use initial metadata of embedded
fields as well, when generating metadata for owning object?
Thanks,

Unfortunately, no. Does it work if you manually change the mappings to
value mappings?Yes, it does. Actually i found out, that i left a mistake in generator,
therefore KODO was not able to determine return type of externalizer
method. Once i've fixed this, i get correct schema being generated without
transfering metadata to owning entity.
