Hi
I am trying to setup a many to many relationship, where the table that
represents the many-to-many relationship cannot be anonymous. It works
fine when I insert a value, but when I try to update a value I get the
following error:
Incorrect or not found field reference name 'brand_class' in descriptor
org.apache.ojb.broker.metadata.ObjectReferenceDescriptor@1240158[cascade_retrieve=true,cascade_store=none,cascade_delete=none,is_lazy=false,class_of_Items=class
creative.beans.BrandClass] for class-descriptor 'creative.beans.BrandParam'
Now, brand_class is a field in the database, so I don't understand what
it is complaining about.
Here are the related tables:
CREATE TABLE brand (
brand_id CHARACTER VARYING(8) NOT NULL,
brand_name CHARACTER VARYING NOT NULL,
is_bookable BOOLEAN DEFAULT 'true' NOT NULL,
agency_code CHARACTER VARYING(8),
consultant_id CHARACTER VARYING(5),
webbook_locn CHARACTER VARYING,
is_white_label BOOLEAN DEFAULT 'true' NOT NULL,
logo CHARACTER VARYING,
colour_1 CHARACTER VARYING(6),
colour_2 CHARACTER VARYING(6),
enquiry_text CHARACTER VARYING,
extra_cond CHARACTER VARYING,
extra_info CHARACTER VARYING,
contact_details CHARACTER VARYING,
to_email_addr CHARACTER VARYING,
from_email_addr CHARACTER VARYING,
cc_email_addr CHARACTER VARYING,
PRIMARY KEY (brand_id)
);
CREATE TABLE extra_enq_field (
id SERIAL NOT NULL,
brand CHARACTER VARYING(8) NOT NULL,
label CHARACTER VARYING(15) NOT NULL,
display_type CHARACTER VARYING(15) NOT NULL,
PRIMARY KEY (id)
);
CREATE TABLE brand_class (
id SERIAL NOT NULL,
label VARCHAR(20) NOT NULL,
is_required BOOLEAN DEFAULT 'false' NOT NULL,
PRIMARY KEY(id)
);
CREATE TABLE brand_param (
brand VARCHAR(8) NOT NULL,
brand_class integer NOT NULL,
value VARCHAR,
PRIMARY KEY(brand, brand_class)
);
I have created classes for all these functions. I will include
BrandParam and BrandClass:
public class BrandParam implements Serializable
{
public BrandParam()
{
}
public BrandParam(BrandClass inBrandClass)
{
mBrandClass = inBrandClass;
mId = inBrandClass.getId();
}
