Description

so I've got this...
public int allRecordsCount(Expression e) {
ObjEntity entity = getContext().getEntityResolver().lookupObjEntity(getObjectClass());
Expression qualifier = null;
<...>
String ejbqlWhereString = qualifier == null ? "" : " WHERE " + qualifier.toEJBQL("a");
String ejbqlQueryString = "SELECT count(a) FROM " + entity.getName() + " a" + ejbqlWhereString;
EJBQLQuery ejbqlQuery = new EJBQLQuery(ejbqlQueryString);
Number count = (Number) DataObjectUtils.objectForQuery(getContext(), ejbqlQuery);
return count.intValue();
}

But I'm getting this exception. Any ideas?
