Hi, We have upgrade an site from 5.1 to 6.0. And after that we get the following error. How can we solve that?

PropertyData object with name "MainBody" already exists

Looks a little bit like this:

I've seen this error is it is a page loop to it self or using shortcut to a page that isn't there.

Kind regards,

Jon Haakon

I have a site that I have upgraded from 4.62B to CMS6 and from time to time I get this exact error. It just appears at random, I haven't been able to see any pattern when it occurs.

Have you found any solution to this? I looked at the links above but they didn't help.

Kind regards,

/Jens

This is a very old question but I recently ran across this same error. There are several SQL queries you can run to look for duplicate property names:

-- Checks the tblProperty table looking for duplicate properties.
SELECT [fkPageDefinitionID]
	,[fkPageID]
	,[fkLanguageBranchID]
	,COUNT(*)
FROM [dbo].[tblProperty]
GROUP BY [fkPageDefinitionID]
	,[fkPageID]
	,[fkLanguageBranchID]
HAVING COUNT(*) > 1

-- Checkes the tblPageDefinition table looking for properties with the same name.
SELECT [pkID]
	,[Name]
	,COUNT(*)
FROM [dbo].[tblPageDefinition]
GROUP BY [pkID]
	,[Name]
HAVING COUNT(*) > 1

-- Checks the tblWorkProperty table looking for duplicate properties.
SELECT [fkPageDefinitionID]
	,[fkWorkPageID]
	,COUNT(*)
FROM [dbo].[tblWorkProperty]
GROUP BY [fkPageDefinitionID]
	,[fkWorkPageID]
HAVING COUNT(*) > 1

-- Checks the tblProperty table looking for two properties with the same name attached to one page.
SELECT [fkPageID]
	,PD.NAME
	,COUNT(*)
FROM [AHAEpi_Stage].[dbo].[tblProperty] P
LEFT JOIN [dbo].[tblPageDefinition] PD ON P.fkPageDefinitionID = PD.pkID
GROUP BY [fkPageID]
	,PD.NAME
HAVING COUNT(*) > 1

If any one of these queries return results you should investiage and delete the offending data row.
