Hi Chris,

Ok, I remove all the domain specific code and I send it.

Thanks,
Arnaud.

Can you send me the hooks you are trying to use, and show me which line does not do the expected behavior?

 

Thanks,

Subject: Re: [grouper-dev] dbVersionDifferentFields and getAttributeOrNull interraction

 

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!  :)

Chris

Thanks,

Arnaud.

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.
