Uwe Allner updated OFBIZ-4857:
------------------------------
Description:
In GenericEntity.set(String name, Object value, boolean setIfNull) after the
necessary type conversions and checks it should first be verified that the new
value is different from the currently set, before the state is set to
changed/modified and observers are notified. E.g. (line 432 ff.):
{code:title=GenericEntity.java|borderStyle=solid}
Object old = fields.get(name);
if(!ObjectUtils.equals(old, value)) {
fields.put(name, value);
generateHashCode = true;
modified = true;
this.setChanged();
this.notifyObservers(name);
}
{code}
Also the store in the GenericDelegator should be dependant on the modified-flag
of the GenericValue to save.
Update operations could be done more elegantly, and execution time would
potentially be saved.
