Hello!

Greetings!
My question is :
"Does not MCMS 2002 only allow exclusive edit of a page by a single
user?"

In our MCMS application when one user is trying to edit a page,
another person can still go to the edit mode of the same page. For
example say user1 has MCMS author rights user2 has MCMS Editor rights.
But user1,user2; both of them can edit the same page at the same time.
When they try to save the page, the first saving say by user1 is fine,
the next saving by user2 says "Overlapped saving". Is it a Bug? Or As
we have modified the basic MCMS workflow so somewhere in the modified
code it got corrupted.

Any help is really appreciated.

Regards.

Hi DG,

this is by design.
There is no way for MCMS to see if the user who opened the posting in IE did
close IE or if he is still editing due to the stateless behaviour of http.
To prevent endless locks of items the item will only be locked when saving
the posting.
If you would like to change this and would like to live with the caveats you
would have to modify the console actions and call AcquireOwnership when a
browser switches to edit mode.
But as indicated: if the user closes the IE window without pressing cancel
or without save the item will stay locked.

Cheers,
Stefan.

Thank you so much Stefan for the clarification. Now I want to make it Exclus
ive edit, so as you pointed, I need to acquire the ownership of the editing 
of the page using AcquireOwnership. Will try.
Thanks again.

Hi Folks,

has anybody sample code for such a modification in the
SwitchToAuthoringReeditAction Class?

Best regards,

Hi Role,

I'm not aware of ready to use sample code.

Hi DG,

check cmsContext.Mode to see if you are in Update mode.

Cheers,
Stefan.

Hi Stefan!

I have tried the following:
protected override void PerformActionBehavior()
{
base.PerformActionBehavior();
Posting pst = CmsHttpContext.Current.Posting;
switch (CmsHttpContext.Current.Mode)
{
case PublishingMode.Update:
{
pst.AcquireOwnership();
CmsHttpContext.Current.CommitAll();
break;
}
case PublishingMode.Published:
case PublishingMode.Staging:
case PublishingMode.Unpublished:
default:
break;
}
}

But whenever I am trying to edit the posting, the PublishingMode is
always other than "update" PublishingMode, so the AcquireOwnership is
never been invoked and the exclusive edit is not happening. But when
the ReleaseOwnership is invoked without ownership acquired by a user
it dooes not throw any exception. So it seems I do not have to check
for Release Ownership whether need to release at all.
Now my question is do I have to set the mode programmatically to
Update at the beginning of PerformActionBehavior say

CmsApplicationContext AppContext = new CmsApplicationContext();
AppContext.AuthenticateAsCurrentUser (PublishingMode.Update);

But I got exception when I tried to set the PublishingMode inside
PerformActionBehavior. Can you please help me to understand this. I
need to make the edit exclusive for a user, once s/he starts editing
no one can use edit command unless that page is saved and submitted.

Thank you.

Hi DG,

that is correct.
That is what I indicated: The Publishing Mode is only switching to update
while you hit the save key. That's the reason for the two postbacks you are
seeing:
- first postback switches to update mode to allow the save
- second postback switches back to unpublished mode.

You would have to implement a similar techique here: when you click on this
button you need to check if the current user already has ownership.
If not, check if you are in update mode. If not do a redirect to Update
mode, aquire ownership and do a redirect back to the original URL.

Cheers,
Stefan
