I am recieving the folloing error

Quote:

net.sf.hibernate.MappingException: property mapping has wrong number of columns: com.fmr.xtrac.hibernate.TTkalArchWorkItemXML.wiXml type: object

this is my mapping file

Code:

[code]<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
    "-//Hibernate/Hibernate Mapping DTD 2.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd" >

<class

    table="T_TKAL_ARCH_WORK_ITEM_XML"

    <id
        name="fileN"
        type="java.math.BigDecimal"
        column="FILE_N"

        <generator class="assigned" />
    </id>

    <property
        name="wiXml"
        type="java.lang.Object"
        column="WI_XML"
        not-null="true"
        length="86"
    />

    <!-- associations -->[/code]

</class>
</hibernate-mapping>

I think the problem is that wiXML is of type object and as a result does not implement Serializable

Any ideas on how to resolve this issue

Hum... I wonder why you map the property as being of type Object...

It sounds not related to the exception your receive, but mapping to the class Object is so weird by itself it could lead to weird exceptions too, I guess.

Let me know about it,
