Creating a Site Column that Looks up an External List causes error when saving site as a template.

Posted By:      Posted Date: September 24, 2010    Points: 0   Category :SharePoint

I'm not sure what the best practice is here, but I'm having a major issue trying to save sites as templates and I think I narrowed it down as to what the issue is.

When I try to save a site as a template, it creates the solution package, but it doesn't activate it.  When I try to activate it manually, I get the following error:

Feature definition with Id e9431ed5-27b1-4c33-9eeb-81b4ace9d372 failed validation, file 'test1ListInstances\ElementsFields.xml', line 481, character 231: The 'SystemInstance' attribute is not allowed.

I opened up the solution package and looked at the ElementsFields.xml file.  I traced the line to this:

<Field Type="BusinessData" DisplayName="Acme People Name" Required="FALSE" EnforceUniqueValues="FALSE" Group="Custom Columns" ID="{55b3bbba-a7e3-4698-9946-648a6b726e9e}" SourceID="{026904fd-f2d0-4e57-a239-c6da838458fa}" StaticName="Acme_x0020_People_x0020_Name" Name="Acme_x0020_People_x0020_Name" SystemInstance="ACME" EntityNamespace="http://????????:28241" EntityName="People" BdcField="FullName" Profile="" HasActions="True" SecondaryFieldBdcNames="0" RelatedF

W/O modifying the content, except setting the output path of the webtemp file to another language, I have the following error when I try to create a site based on this template :

I've taken a look at OOB site templates, and I don't see what is missing.

I'd appreciate any help.

Error creating site template for publishing site



I am trying to create site template for publishing site in SharePoint 2010.

I have a publishing site and have created site template for the same using _layouts/savetmpl.aspx.

But when I tried to create site from that template in the same site collection it throws error, actually it creates the site but not able to set the home page as /pages/default.aspx. If I edit the url as http://<new site created>/pages/default.aspx the site is working fine.

Saving Site as a Template Results in an Error in Migrated SharePoint 2010



We've migrated our corporate SharePoint 2007 farm to 2010. We're having an issue with Saving Sites as Templates. I've created a blank site and attempted to Save the Site as a template and receive an error. The logs have the following below about the error:

System.InvalidOperationException: Error generating solution files in temporary directory.

The strange thing is, we have 3 web applications and only one exhibits this behavior.

Any ideas where I can look further?

Thanks in advance.


workflows when saving site as template with content

I have have a MOSS 2007 site on a production server with custom workflows.  I saved the site as a template with content and used the template to create a sibling site.  I am testing it and the workflows aren't working.  Is this to be expected? I have read that workflow don't work when saving between development and production, but I can't find anything that addresses both sites being on production. Will I need to recreate the custom workflows by hand?

SOLUTION: Renaming the Title list column globally across the site collection

So, you screwed up like I did, and modified the Title display name of the Item base content type and it has renamed ows_Title across every list in your site collection? Here's how you fix it: //WARNING //If you have come this far, be aware that this tool is a blunt axe. With it, you can cause //all sorts of mayhem and chaos in your site collection. So, to use this, you must be desperate. //or possibly dumb. Apparently, I'm just as dumb as you, because I did it. This is why I wrote //this stupid thing, so stupid people like us can go right on being stupid. //Your choice of weapon in this battle amuses me. Shall we begin? using System; using System.Collections.Generic; using System.Text; using Microsoft.SharePoint;   namespace RenameField {     class Program     {         static void Main(string[] args)         {             if (args.Length < 3)             {                 Console.WriteLine("Usage: RenameField <url-to-sitecollection> <internal-field-name> <new-fieldtitle>");               &n
