Hi all,
I'm experiencing a stange behaviour of castor,
where it
accepts number from a sqlDB with 1 decimal (12.5),
but not with 2 (12.52).
The error message does not correspond to the problem at all (see below)
---------------------------
The story :
Due to the euro currency changes, some prices have now received a 2nd decimal.
Kaboum :
after changing any value of a record that has 1 field
with 2 decimals,
the following 'commit' causes
org.exolab.castor.jdo.ObjectModifiedException:
Transaction aborted:
Object of type xxxx.Stage with identity 3
has been modified by a concurrent transaction
It doesn't make sense to me :
1/ in the DB, the value is stored in a double :
base_price double DEFAULT '0' NOT NULL,
2/ in mapping.xml and java, it's a double too :
<field name="basePrice" type="double" >
<sql name="base_price" />
</field>
------------------------------------------------------------------------------------
The simplest test that reproduces the problem :
db.begin();
stage_3 = Stage.get(db, 3) ;
stage_3.setAccountCard("qsdf") ; // could be any other field,
of any type
db.commit(); => throw exception
case 1: in the DB, I set the basePrice value to 12.5
=> OK (1 decimal)
case 2: in the DB, I change the basePrice value to 12.52
=> fail (2 decimals),
with the following stact trace :
org.exolab.castor.jdo.ObjectModifiedException:
Transaction aborted: Object of type
cirb.tele.project.jjjynetv2.dataModel.Stage
with identity 3 has been modified by a concurrent transaction
