(Managed) Inverse relations and map mapping

Question

Hi.
Is there any limitation in using (managed) inverse relations together
with map mapping? I've tried to setup my test model like this: a single
City object holds references to many Street objects. City has "name"
attribute , collection named "streetsList" (1-n with Streets) and map
named "streetsMap"(n-to-many map with Streets). Street objects have just
simple "name" attribute and single "city" reference to City object.
What I'd like to achieve is have Kodo to set inverse relation on Street
object (relation "city") when I put Street object into City's
"streetsMap". This works fine when using collection ("streetsList") but
doesn't seems to be working when map-mapped relation field is in use.
How do I use Kodo's inverse relations manager with map fields?
Everything is OK when I set the inverse side of relation manually
(setting Street.city field when putting Street to City.streetsMap) - but
I'd like InverseManager to do it!
My configuration:
- kodo.properties:
kodo.InverseManager: true(ManageLRS=true)
- package.mapping:
<class name="City">
<jdbc-class-map type="base" pk-column="JDOID"
table="TEST_CITY"/>
<jdbc-class-ind type="metadata-value" column="JDOTYPE"/>
<field name="name">
<jdbc-field-map type="value" column="CITY_NAME"/>
</field>
     <field name="streetsMap">
     <jdbc-field-map type="n-many-map" key-column="MAP_KEY"
table="TEST_STREET_MAP"
     value-column.JDOID="STREET_JDOID"
ref-column.JDOID="CITY_JDOID"/>
     </field>
<field name="streetsList">
          <jdbc-field-map type="one-many" ref-column.JDOID="CITY_JDOID"
table="TEST_STREET"/>
</field>
</class>
<class name="Street">
<jdbc-class-map type="base" pk-column="JDOID"
table="TEST_STREET"/>
<jdbc-version-ind type="version-number" column="JDOVERSION"/>
<jdbc-class-ind type="metadata-value" column="JDOTYPE"/>
<field name="name">
<jdbc-field-map type="value" column="NAME"/>
</field>
<field name="city">
          <jdbc-field-map type="one-one" column.JDOID="CITY_JDOID"/>
     </field>
</class>
- package.jdo:
<class name="City">
          <extension key="jdbc-class-ind-value" vendor-name="kodo" value="1"/>
          <field name="streetsMap">
               <map key-type="String" value-type="Street"/>
               <extension vendor-name="kodo" key="inverse-owner" value="city"/>
               <extension vendor-name="kodo" key="lock-group" value="none"/>
          </field>
          <field name="streetsList">
               <collection element-type="Street"/>
               <extension vendor-name="kodo" key="inverse-owner" value="city"/>
               <extension vendor-name="kodo" key="lock-group" value="none"/>
          </field>
          <field name="name">
          </field>
     </class>
     <class name="Street">
          <extension key="jdbc-class-ind-value" vendor-name="kodo" value="2"/>
          <field name="name">
          </field>
     </class>

Unfortunately, inverse management is not available for Maps. We hope to
make it available in a future release.
