I get following error when trying to use Criteria with filtering on custom user type with applied filter:
{noformat}
java.lang.ClassCastException: org.hibernate.type.CompositeCustomType cannot be cast to org.hibernate.type.ComponentType
at org.hibernate.engine.spi.QueryParameters.processFilters(QueryParameters.java:575)
at org.hibernate.engine.spi.QueryParameters.processFilters(QueryParameters.java:524)
...
{noformat}
There is a bug in _QueryParameters.processFilters_:
{code:java}
* if ( type.isComponentType() ) { *
// should process tokens till reaching the number of "?" corresponding to the
// numberOfParametersCoveredBy of the compositeType
int paramIndex = 1;
* final int numberOfParametersCoveredBy = getNumberOfParametersCoveredBy( ((ComponentType) type).getSubtypes() ); *
while ( paramIndex < numberOfParametersCoveredBy ) {
final String nextToken = tokens.nextToken();
if ( "?".equals( nextToken ) ) {
paramIndex++;
}
result.append( nextToken );
}
}
{code}
It use _Type.isComponentType_ to check whether the type is a composite type, but then the type is casted to ComponentType. According to javadocs _Type.isComponentType_ returns true for CompositeType as well.
This is likely regression from HHH-10991 |
