SharePoint Document Library Provisioning

Question

I have come across an issue which occurs when provisioning a new Document Library and adding content to it via features.

The following issue won't happen as long as there is an Activation Dependency set for the content feature.

The scenario: I have 2 features, the first provisions a basic Document Library on my site.

Document Library Feature.xml:

The activation receiver:

using (SPWeb site = (SPWeb)properties.Feature.Parent)
            {
                Guid libraryID = site.Lists.Add("MyNewLibrary", "A New Document Library", site.ListTemplates["Document Library"]);
                //SPList newLibrary = site.Lists[libraryID];
                //newLibrary.OnQuickLaunch = true;
                //newLibrary.BreakRoleInheritance(false);
                //newLibrary.Update();

                site.Update();
            }

Content Feature.xml:

<Feature xmlns="http://schemas.microsoft.com/sharepoint/"
   Hidden="False"
   Id="A63C95A3-616A-4d4c-8B9B-6A9D9AF2A2E1"
   Title="My New Content Test"
     Description="Adds some base content to MyNewLibrary"
   Scope="Web">
  <ElementManifests>
    <ElementManifest Location="manifest.xml"/>
  </ElementManifests>
</Feature>

Manifest.xml:

<Elements xmlns="http://schemas.microsoft.com/sharepoint/"&gt;
  <Module Name="MyNewLibrary" Url="MyNewLibrary" List="101" Path="MyNewLibrary">
    <File Url="sample.txt" Type="GhostableInLibrary" />
    <File Url="TextFile1.txt" Type="GhostableInLibrary" />
    <File Url="TextFile2.txt" Type="GhostableInLibrary" />
    <File Url="TextFile3.txt" Type="GhostableInLibrary" />
    <File Url="TextFile4.txt" Type="GhostableInLibrary" />
  </Module>
</Elements>

When the Content feature is activated before the document library has been created I receive the following error message from SharePoint:

Failed to instantiate file "sample.txt" from module "MyNewLibrary": The specified list does not exist.   at Microsoft.SharePoint.Library.SPRequestInternalClass.EnableModuleFromXml(String bstrFeatureDirectory, String bstrUrl, String bstrXML) 
   at Microsoft.SharePoint.Library.SPRequest.EnableModuleFromXml(String bstrFeatureDirectory, String bstrUrl, String bstrXML)

I then return to the feature management screen and activate the document library. The activation happens without any errors being generated, but the url now has a 1 appended to it. So instead of being /MyNewLibrary as would be expected, the url is /MyNewLibrary1.

The only way I have found to correct this after it occurs is to delete the site and recreate it, then activate the features in the proper order.

I am wondering if any one else has come across this issue and can shed light on where this mysterious '1' comes from?

Thanks. Scott
