I have a custom contenttype which inherits from documentset. Further for the custom contenttype exists a custom docsethomepage.aspx (WelcomePage). Now the problem is, if I create a subfolder (contenttype: SPFolder) in the documentset the set link is wrong. Clicking on the subfolder means getting redirected to the documentsethomepage.aspx (that's the problem)

SPFolder Xml

```
< z : row xmlns:z='#RowsetSchema' ows_ContentTypeId='0x012000CE8B7947004C423CB7580EBD0958B8200061E0E27CC804418F8C868584C1C096B500E2C3ADD1BCC4294FA4F0825E9CBAE923' ows_FileLeafRef='35;#Storno' ows__dlc_DocId='AAEPW6D2E46Z-138-35' ows__dlc_DocIdUrl='http://.../_layouts/DocIdRedir.aspx?ID=AAEPW6D2E46Z-138-35, AAEPW6D2E46Z-138-35' ows_ID='35' ows_ContentType='Stornierte Elemente' ...

```

An edit on the fields ows\_\_dlc\_DocId, ows\_\_dlc\_DocIdUrl, WelcomePage, ReplaceLink(old, new) didn't help.
Has anybody an idea fixing this 'bug'?
