Hello!
I use Intellij IDEA 95.24; OpenJPA 1.2.2 and MySQL 5 database.
All java entities - mapped to mysql tables were created by IDEA wizard.
Everything was OK, but I have met 1 strange problem:
In one of my MySQL tables:
-------------------
CREATE TABLE kl_mytable (
id_klmytable int(11) NOT NULL auto_increment,
name char(100) NOT NULL,
n_link int(11) NOT NULL,
id_country int(11) NOT NULL,
PRIMARY KEY (id_klmytable),
KEY id_country (id_country),
CONSTRAINT kl_mytable_fk FOREIGN KEY (id_country) REFERENCES country
(id_country)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 ROW_FORMAT=COMPACT
-------------------
there is a problem with the field "n_link".
IDEA has generated a proper entity mapping:
+++++++++++++++
private Integer nLink;
@javax.persistence.Column(name = "n_link")
@Basic
public Integer getnLink() {
return nLink;
}
public void setnLink(Integer nLink) {
this.nLink = nLink;
}
+++++++++++++++
But in the logs I see:
===============
23797 NewPersistenceUnit TRACE [http-8080-Processor25] openjpa.MetaData -
Initializing mapping for "server.domain.klmyta...@28318025".

===============
It means, OpenJPA does not resolves this field "n_link" and in the Query it
always returns NULL as its value.
When I try do debug a little deeper, I also see - "no field named" exception
about this "n_link" field,
but IDEA sees this field and even helps me to create the Query with code
completion, using this "absent" (like OpenJPA thinks) field.
So, please, help.
What am I doing wrong?
