Summary: java.math.BigDecimal always dirty
Initial Comment:
JBoss 3.2.3
Sun JVM 1.4.2_03
MS SQL Database with Microsft SQL 2000 Driver SP2
I have entity beans with java.math.BigDecimal fields.
The problem I have is that JBoss always updates all
BigDecimal fields even if they are not modified by my
code.
I traced in the source and found a possible explanation:
BigDecimal gets the default INVALID_UNLESS_NULL
CMPFieldStateFactory. Looking at the isStateValid
method of this class:
public boolean isStateValid(Object state, Object
fieldValue)
{
return state == null ? fieldValue == null : false;
}
and tracing trough the code gives me a non null state
and fieldValue even if not updated. So isStateValid
returns false which marks the field as dirty which then
triggers an update.
I am fully available if more info required.
