Showing last updated structures

Hi,

I'd like to have a component that show last edited structure (at leat page).
I think it's not possible yet. Correct me if wrong.

Does adding an inst var timestamp in structure is the way to go ?

Thanks

Cédrick

ok I must be wrong as there is the change command oops...

What I'd like is a small change component that can be embeded and also display (or not depending on a setting) the last update information.
I'd like also to have a checkbox so as it's possible to record this information (in case of correcting a typo for instance)...
I'll investigate on changes and I'll come back later on that... ;)

I'm tired I mean't:

What I'd like is a small change component that can be embeded.

Then also to display (or not depending on a setting) the last update information at the start (or end) of a page.

I'd like also to have a checkbox so as it's possible to record ***or not*** this information (in case of correcting a typo for instance)...

I'll investigate on changes and I'll come back later on that... ;)

there is a checked inst var in PRCommand. I think I could use similarly an inst var, or a wrapper for timestamp to associated it with a boolean...
What would you do ?

Thanks

checked seems to be use only in PBComment...

PRCommand>>isChecked
"Answer ==true== if the command should be checked before execution, e.g. the method ==#doValidate== should be executed at all."

If you use PRHistoryPersistency or any of its subclasses as the
persistency mechanism you get this information:

aKernel persistency historyFor: aStructure

This answer a collection of commands that have been executed on
aStructure. You can for example filter it for edit commands to get all
the edit operations (this is what the subclasses of PRHistoryView are
doing).

You can add such a field to PRCommand by adding a new description.

And then you display the data using the technique I showed in the
previous mail.

I don't understand. There is already a time-stamp recorded within all
the commands (see inst-var refs to 'timestamp' in PRCommand). checked
is something else (see inst-var refs to 'checked' in PRCommand).

As any Magritte or Pier object you can just use #propertyAt: and
#propertyAt:put: and a Magritte description for clean extension
without having to override or change something in the existing code.

This is used in PRPersistency. This is an important part of the
persistency mechanism and allows to replay commands at a later point
in time without checking the validation conditions. I agree, that the
implementation should be improved for readability.

Cheers,

This is icing on the cake :)
I want some edit not being displayed in the "pages last updated"
component. I guess I need to add a property because checked is use for
persistency reason. When unchecked (trough the description) the
property record will be set to false so this change won't be
considered... I'll give a try soon.

Thanks a lot
