[Seaside] Glorp-Seaside-callback not Working

[Rajeev Lochan]

Hi Ron,
I tried to implement what you hinted, no progress.

I changed my code to

html
        form: [self session
                commit: [temp := self session
                                readOneOf: BlogPost
                                where: [:each | each persistentId = '1'].
                    self session register: temp.
                    html textInput value: temp title;

                        callback: [:value | temp title: value].
                    html submitButton
                        callback: [self session register: temp];
                         text: 'Update']]


I am registering before change as you said, but doesnt change the title. (I
am registering twice though)


But, even if I dont register the object, before changing. It does update if
I use normal setter technique. (Snippet below)

html
        form: [self session
                commit: [temp := self session
                                readOneOf: BlogPost
                                where: [:each | each persistentId = '1'].
                    temp title: 'some Title'.
                    html submitButton
                        callback: [self session register: temp];
                         text: 'Update']]




In Glorp Tutorial by Roger Whitney, he updated in just unitOfWork and also
without registering it.

"   A UnitOfWork will keep track of the changes we make in objects. The
following will retrieve a
person, change the first name of person and then write the changes back to
the database.

session beginUnitOfWork.
foundPerson := session readOneOf: Person where: [:each | each firstName =
'Jose'].
foundPerson firstName: 'RamJet'.
session commitUnitOfWork

When we start a UnitOfWork it records all the objects we read from the
database. When the
UnitOfWork is committed it writes all the changed objects back to the
database."


As much I understand, it has something to do with
self session commit:[ ........... html textInput value: callback:
...........]


BTW, I am not using Magritte in my proposed application. So Ramon's Active
Record for Magritte would possibly not help me much.

Thanks in advance.
