Hi

Could be due to Searches.GetByGuid returning objects of
type HierarchyItem.

It can't implcitly convert it to a Posting. Have you tried
this:
posting = CType(context.Searches.GetByGuid(guid), Posting)

Trevor

passing
posting.Name

Also ensure that the posting you are looking for is Published.
The CmsApplicationContext is only authenticated for Published mode in the
code below.

Regards,
Stefan.

Hi Bob,

this can happen if

1) the node cache is to small to hold all items or
2) this item has never been requested before and is requested from the
database while it is updated by an import job

Not the whole database is locked only the items which get updated while they
are updated.
If the node cache is big enough and not flushed short before you run the
import the chance to hit an item that never has been hit before exactly in
the small timeframe while it is updated in the database is very very low.
But it exists.

Your mail seem to indicate that it happens very often in your situation - so
either your node cache is not big enough to hold all items or you cleaned
your node cache short before running the import (e.g. restart of the
application pool).

30 minutes I have a custom .exe that export all the new postings from the
first environment to the second environment.
received this error:
channel.postings and a search operation....
custom .exe), cms 2002 locks the database and the user can access only the
cache...is it possible that the reason of my error is that I navigate during
an export/import operation ???

Hi,

I have a problem getting my channels from the Root Channel Gallery. Till
last weekend before I did the DCA to another database, it was working fine.
Now, when I changed back and executed the following code, I am getting the
above error.

CmsHttpContext cmsContext = CmsHttpContext.Current;
Channel startChannel = (Channel)
cmsContext.Searches.GetByPath(startChannelPath);
ChannelCollection channels = startChannel.Channels;

Can someone please help me what may have gone wrong?

Thanks,
Nanda

Hi Nanda,

in which line do you get this error?
I assume in the last one.
Then the GetByPath does not return an object.

If this is the case then either the current user does not have rights to
this channel or the path passed to this method is invalid.

Cheers,
Stefan

Hi Stefan,

Thanks for the reply. Yes, the error was coming in the last line.

I have tried checking the Logged in User for the HTTPContext. It is using
the Administrator User of MCMS. I have even tried to login to Site Manager
with same credentials and I could see all the Channels in every gallery. The
problem still persisits. Please help.

Thanks,
Nanda

Hi Nanda,

please debug the code and verify that the correct path is passed to this
routine.

Cheers,
Stefan

Hi Stefan,

I debugged the code and also the permission sets. The problem is coming when
I have enabled the guest access from NRConfig. If it is enabled, my program
has been taking default guest access and throwing error that the user is not
authenticated. When I remove guest access, it asks for the authentication
even and displays the set of postings.

Can you please tell me whats the best configuration on guest access for a
MCMS site? I have even tried to add subscriber rights. But even then I had
been prompted for Login access.

Thanks!!

i Nanda,

If you are logged in as guest then you are acting as the configured guest
user.

Which object is " throwing error that the user is not authenticated"?
Please post the code and outline the line that is causing this.

Cheers,
Stefan
