HRESULT: 0x81070201 Exception

Okay okay, this is actually something very basic, but it happend now a couple of times to me. If you work on a Feature that defines a custom SharePoint List, you can run into the following Error while activating it (in this case during Site Provisioning by definitions in onet.xml):

The element 'MyList' of type 'ListInstance' for feature 'MyListFeature' (id: 794958c5-fede-4e1f-aa96-d9fcd087945e) threw an exception during activation: Exception from HRESULT: 0x81070201

The reason for this error is, that SharePoint can't find the related schema.xml file for the list to define. This can happen, if

• You simply forgot to write an schema.xml file


• or, what is more realistic, the Name Attribute in ListTemplate is not the same as the Folder Name you have the schema.xml File stored in.

The Name-value of the ListTemplate tag must match the name of the folder you have your schema.xml file stored in:


<ListTemplate
Name="MyListDefinition"
Category="Custom Lists"
DisplayName="MyList"
...
