[ojb-users] proxyReference=true --> type mismatch

[Pelzer, C. <Pe...@LA...>]

Hi there,

Here my first OJB-Question :-)

Switching the proxyReference in the repository.xml to 'true' always gives us
a 'field type mismatch'.

Exact log:
com.bla.container.MNUP:0000000000000008
[DEFAULT] ERROR: field type mismatch
java.lang.IllegalArgumentException: field type mismatch

It only works when we delete the proxyReference in MNUP and set the
class.proxy in FIRP to dynamic.

The MNUP-Class is defined in the repository.xml like this:
    <ClassDescriptor id="5">
        <class.name>com.bla.container.MNUP</class.name>
        <class.proxy>dynamic</class.proxy>
        <table.name>MNUP</table.name>
        <FieldDescriptor id="1">
            <field.name>m_id</field.name>
            <column.name>ID</column.name>
            <jdbc_type>CHAR</jdbc_type>
            <PrimaryKey>true</PrimaryKey>
        </FieldDescriptor>
.
.
.
        <ReferenceDescriptor id="2">
            <proxyReference>true</proxyReference>
            <rdfield.name>m_FIRP_MenueFirmId</rdfield.name>
            <referenced.class>com.bla.container.FIRP</referenced.class>
            <fk_descriptor_ids>11</fk_descriptor_ids>
        </ReferenceDescriptor>

The FIRP-Class is defined like this:
    <ClassDescriptor id="8">
        <class.name>com.bla.container.FIRP</class.name>
        <class.proxy>dynamic</class.proxy>
        <table.name>FIRP</table.name>
        <FieldDescriptor id="1">
            <field.name>m_id</field.name>
            <column.name>ID</column.name>
            <jdbc_type>CHAR</jdbc_type>
            <PrimaryKey>true</PrimaryKey>
        </FieldDescriptor>
.
.
.
        <CollectionDescriptor id="5">
            <proxyCollection>true</proxyCollection>
            <cdfield.name>m_collection_MNUP_MenueFirmId</cdfield.name>
            <items.class>com.bla.container.MNUP</items.class>
            <inverse_fk_descriptor_ids>11</inverse_fk_descriptor_ids>
        </CollectionDescriptor>



Hope these infos help understanding our problem... Any ideas?
