I migrated my application from grails 1.0.2 to grails 1.3.5. Since then i am facing issues while executing some of the existing database queries. The data base used is H2. Following error is coming while attempting the following query" "appointment = AuditAppointment.findByAudit(currentAudit) "

org.h2.jdbc.JdbcSQLException: Parameter "#1" is not set; SQL statement:select this_.id as id573_0_, this_.version as version573_0_, this_.appointment_address_id as appointm3_573_0_, this_.appointment_contact_id as appointm4_573_0_, this_.appointment_date as appointm5_573_0_, this_.contact_date as contact6_573_0_ from audit_appointment this_ where this_.id=?

Following is the code:
class Audit {
//List parties;

Boolean currentAudit

AuditAppointment auditAppointments;

String toString() {
"Audit For: ${this.employerName}"
}

Class AuditAppointment contain relation (belongsTo) with Audit class
like,
class AuditAppointment {
static hasMany = [appointmentHistory:AppointmentHistory,
appointmentComments:AppointmentComment]
static belongsTo = [audit:Audit];

first the query "def currentAudit = Audit.findByCurrentAudit(true)" is executed.First query is returning the records.
The results(object of Audit) are passed to the 2nd query:
"appointment = AuditAppointment.findByAudit(currentAudit)"

internally it creates hibernate query like, select this_.id as id573_0_, this_.version as version573_0_, this_.appointment_address_id as appointm3_573_0_, this_.appointment_contact_id as appointm4_573_0_, this_.appointment_date as appointm5_573_0_, this_.contact_date as contact6_573_0_ from audit_appointment this_ where this_.id=?

I am new to H2, not getting idea how to resolve the issue.

Thanks,
Ayush
