restrictions problems followup..

[Eitan Suez]

hi nachos,

  following up on the issues you brought up regarding exceptions when
  setting/applying authorization restrictions on commands.

  1. you cited two specific exceptions.  the first:
org.hibernate.HibernateException: instance not of expected entity type: com.u2d.element.TypeCommand is not a: com.u2d.element.Command
  i have tracked down.  TypeCommand is a command added on a type by marking the method
  static.  i had overlooked letting hibernate know about this class, so when it had to persist
  the command in question, it threw an exception.  this is now fixed in subversion


  i have not yet reproduced the second exception:  NonUniqueObjectException.  i wonder if it might
  perhaps triggered by the first exception (above).  i will continue attempting to generate
  this same exception, and will then proceed to add a fix.

  2. you also mentioned a bug with identity fields and validation, again producing a hibernate
   exception.  i will track this one down next.

you'd mentioned that attempting to save
an instance with a blank value for an identity field throws
an exception.

i just retrofitted sympster.Speaker.name to be an identity field
for testing this issue. so far i cannot reproduce. attemtping to
save is blocked by a validation error which forces me to enter
a name. subsequently saving works in this scenario.

can you give me more detail in your case? what is the type of the
identity field? can you reproduce it every time?

thanks,

Hi Eitan:

bug with identity fields and validation:

When I want to save an object and it has a duplicate key, the system thrwon a validation message (cannot save object: duplicate value for a unique field), which is correct; if I changed the value of the unique file and save the object, the system thrown the next message on interface: "Object has been modified by another user, please refresh the object!" (this object it isn't on the data base yet, so I can't refresh it, and it isn't appear the refresh button on the editable interface). The type of the field is TextEO (It is a String). This error always appear.

I think that the bug with the add restrictions on objects has been resolved, but I didn't prove it very well.

Thank for your help

[Eitan Suez]

thanks.  ok now i understand how to reproduce the issue with the identity field.
i just tested this in sympster with speaker.name (which is now marked as an
identity field / unique).  the error doesn't manifest itself.  so perhaps it's specific
to the case where the field is a TextEO.  will try to test that case.
what database are you using?

I am using Postgresql 8.3

[Eitan Suez]

ok, i am now able to reproduce this issue, using postgresql.
thanks,

[Eitan Suez]

ok, this should now be fixed.

Thanks Eitan, the bug has been resolved.

Hi Eitan:

I have bad news, I have the same error when I assigned restrictions to an object on the interface. I was assigning restrictions for a time, and then the system thrwon next exceptions:

org.hibernate.HibernateException: instance not of expected entity type: com.u2d.element.TypeCommand is not a: com.u2d.element.Command

Then if I tried to assigned more restrictions to another object, the system thrown next exception: org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session: [com.u2d.element.EOCommand#162]

This is the first exception that my system thrown:

I found that the system thrown the exception when I assigned restrictions to this action:

 @Cmd
    public static Reportable reporteRequerimientos(CommandInfo cmdInfo) {
        return new Reportable() {
            public String reportName() {
                return RutaXmlReportes.REPORTE1;
            }

            public Properties properties() {
                return new Properties();
            }

            public TableModel tableModel() {
                return ConsultasPredefinidas.requerimientos().tableModel();
            }

            public ReportFormat reportFormat() {
                return ReportFormat.PDF;
            }
        };
    }


Thanks for your help

hi nacho,
  i forgot to tell you that the fix needs to be made to your application (sorry).
  that is, you need to revise your copy of src/persistClasses.st to match
  that of, for example, Sympster.  then it will work.  sorry about this oversight.

hi eitan:
I'm still experiencing a lot troubles with this. When I build a jws dist and run it, the system throws the following exception when I add a new restriction:

Once this exception is thrown, I can't add another restriction. If I execute the program again, (through ws or the IDE), the problem persist.

Thanks for your time.

[Eitan Suez]

ok, i'll take another look and try to reproduce.  perhaps tomorrow.

Hi Eitan!

Could you reproduce the bug with restrictions and jws?

sorry, not yet.
