Hi!
I have created a custom placeholder control exactly following the tutorial f
rom MS.

I have also generated a Strong Name for my control using the SN utility. In 
my custom control projekt in AssemblyInfo.cs i have added my snk-file refren
ce [assembly: AssemblyKeyFile(" C:\\MyPlaceholderControls\\MyPlaceholder
C
ontrols.snk")].

Then after compilation the dll is successfully added to C:/WINNT/assembly.

Finally i have added the definition of my placeholder control to the MCMS co
nfig file with the right assemblyname, version-nr, token, classname and so f
orth. Everything fine so far.

The problem occurs when I'm opening my project i VS.Net. I get a message tha
t says: "Could not get the root template gallery". In details/more informati
on it says:

Error message:
The type 'McmsWebControlLibrary.PlaceholderControls.McmsXmlPlaceholder' foun
d in the configuration file 'C:\Program Files\Microsoft Content Management S
erver\Server\config\Microsoft.ContentManagement.Publishing.config' is not a 
valid PlaceholderDefinition
type.

Time at which error occurred:
2004-02-27 17:06:45

Exception type:
Microsoft.ContentManagement.Publishing.CmsPublishingConfigurationException

Machine on which error occurred:
OVEKERW2KS1

Error AppDomain:

Error thread ID:

Searching the Internet indicates that this is a permission problem in MCMS!!
!??? I am running VS.Net and MCMS on the same machine logged in as administr
ator. Something seems to be wrong with the PlaceholderDefinition type?

I get the same problem with the same procedures in the Woodgrove.Net McmsXml
Placeholder example.

Thanks!

Hi,

for a placeholder control no strong name is necessary - only for a
placeholder definition!
Usually you will not place it in the GAC but add it to the toolbar.

The error message you receive is not related to your placeholder control.
Check out this article for possible reasons:

Cheers,
Stefan

Hi,

you should not add your placeholder definition to the McmsWebcontrolLibrary.
Rather than create a standalone assembly for this. - and don't mix up
placeholder controls and placeholder definitions.
This are completly different things!

As you see: the error message seems to indicate that you are trying to add a
placeholder control to the placeholder definition list in the config file
rather than a placeholder definition.

Cheers,
Stefan.

> Hi and thank you for your resonse to my problem! Yes your right, but I did
forget to mention that this actually IS ment to be a custom placeholder
definition. I want it to appear in the list among the other predefined
placeholders when I'm creating a new MCMS Template. Further I have been
through the article you suggest but it's not any of these problems. I think
the last line listed in the detailed trace is important:
>

Server\Server\config\Microsoft.ContentManagement.Publishing.config' is not a

i think that the defintion in the config-file is OK and that the problem is
not that of the root template gallery problem. A misspelling for example for
my defintion in the config file is immedately listed in the application
event log and does not result in an error when starting VS.Net. In this case
the Template explorer window opens corrrectly and the templates appears as
they should. On the other hand when "my error" occurs the Template explporer
window opens but no templates are shown in it.

Hi again!

You are right ofcourse! Finally I got it! It is exactly as you suspect. I ha
ve mixed controls with definitions and thats my only problem.
Thank you for leading me right!
