Hi,

I still have the same kind of problem, even with the transactional support activated.


For instance, in the groupPreUpdate method and it looks like if the set returned by dbVersionDifferentFields was correct only after the first call of getAttributeOrNull.

The second point is that it changes the behaviour of the groupPostUpdate method. If there is a call of getAttributeOrNull in groupPreUpdate method, I can retrieve the previous values of the group in groupPostUpdate via dbVersion. If the method is commented I cannot: there is no difference between the previous and the current values of the group.

I don't know if another configuration error could be the cause of this behaviour...

Regards,
Arnaud.

I answer to myself,

I have made a mistake with the mysql db (MyISAM instead of InnoDB) :-[
.
I think this could explain my problems !
    

That is weird... and I am very glad you figured it out!  :)

Thanks,

Hi everyone,

Is it normal that call of the method dbVersion change the result of
the method dbVersionDifferentFields ?

For instance the code :

       final String currentExtension =
group.getAttributeOrNull(EXTENSION);
       LOGGER.debug(" (1) ==> " + group.dbVersionDifferentFields());

       final Group previousValues = group.dbVersion();
       LOGGER.debug(" (2) ==> " + group.dbVersionDifferentFields());

       final String previousExtension =
previousValues.getAttributeOrNull(EXTENSION);
       LOGGER.debug(" (3) ==> " + group.dbVersionDifferentFields());

Produces the output:

    (1) ==> [attribute__Définition, modifyTime, name, displayName,
extension, displayExtension, description]
    (2) ==> [attribute__Définition, modifyTime, name, displayName,
extension, displayExtension, description]
    (3) ==> [modifyTime]

I am trying to use the dbVersionDifferentField to determine when my
hooks should be executed and I have several tests but the first one
changes the results of the other tests. I think I could work with a
clone of the set returned by dbVersionDifferentFields but I would
      

like
    

to understand.

I have also noticed that a single change in a group (via the
grouper-UI) can trigger several time the same method in a GroupHooks
class. One time with the attributes and one time with only the
modifyTime attribute.


Thanks,
Arnaud.
