I have the following as part of my definition of a FilterField:
Code:
private Set details;
private Comparator comparator = new FilterFieldDetailComparator();
public FilterField() {
details = new TreeSet(comparator);
}
The relevant part of the hibernate mapping file I have shows:
Code:
<set
name="details"
table="PROSPECT_FILTER_FIELD_DETAIL"
lazy="false"
cascade="all" sort="com.genalytics.prospect.domain.FilterFieldDetailComparator"
>
<key
column="PROSPECT_FILTER_FIELD_ID"
>
</key>
<composite-element
class="com.genalytics.prospect.domain.FilterFieldDetail"
>
<parent
name="filterField"
/>
<property
name="value"
type="java.lang.String"
update="true"
insert="true"
column="VARIABLE_VALUE"
/>
</composite-element>
</set>
The comparator could be any comparator--even one that simply returns 1 and I get the exception below:
