Hello everybody.

When I create an IlikeExpression Object through the Restrictions.ilike method for doing a query to my Database, sending as first parameter the name of a property properly defined in the configuration file of hibernate and correctly mapped to a column of my database, and as second parameter, an object of type ContentType, which is also mapped to a table of my database, when I do a query with this restriction, hibernate shows me the next result:

Query:

DetachedCriteria criteria = createDetachedCriteria(criteriaCollection, null);
criteria.setProjection(Projections.rowCount());
resultList = daoService.findByCriteria(criteria);

in the criteriaCollection is saved the IlikeExpression Object.

And, this is the error:

IllegalArgumentException in class: com.onetwo.runtime.repository.contenttype.ContentType, getter method of property: fullName
[2008-01-29 10:00:29,044] [ERROR] [XSearchServiceImpl.java] [search] [26] IllegalArgumentException occurred calling getter of com.onetwo.runtime.repository.contenttype.ContentType.fullName; nested exception is org.hibernate.PropertyAccessException: IllegalArgumentException occurred calling getter of com.onetwo.runtime.repository.contenttype.ContentType.fullName

It is very strange because if I do the same query with the same parameters with an like restriction, the query works good.

The code of the ContentType Class is basically a bean with the properties defined on the hibernate configuration file, with the getters and setters properly defined.

This is a piece of code of the hibernate configuration file:

<class name="com.onetwo.runtime.repository.content.metadata.ContentMetadata" table="METADATA">
<cache usage="read-write"/>
.
.
.
<component name="contentType" class="com.onetwo.runtime.repository.contenttype.ContentType">
<property name="fullName" column="CONTENT_TYPE" type="java.lang.String" not-null="true"/>
</component>
.
.
.

the query is done on the METADATA table, but note that the contentType is a property of this table which type is ContentType.
