Hello Vitaly,

Could you check the version you used to upgrade your project? If you have used build 4.0.1030.0 to upgrade your project this is not supported upgrade path.

Hello Ivan,

Thank you for your help. I've used Build 4.0.992.0 to upgrade.

Hello Vitaly,

Thank you for the additional information.

Can you please check if all of the pages are using the same page template? Also do you get this exception for newly created pages?

I am also getting this error on a brand new build 1210 database when users of certain roles attempt to edit a page.  Please help!!!

The page template is a custom masterpage.  The roles permitted to edit the page are custom.  Administrators can edit the page no problem.

Hi Valerie,

What are the permissions to edit the template and to see the place holders for the custom role?

Best wishes,

Radoslav,

The permissions to edit the template were set to "Designers" (a role we do not use).  I changed it to "All Backend Users" (a role which all of my custom role users also have) and still see the same result.

I'm not sure I understand the second half of your question:  "...and to see the place holders for the custom role?"

Additional notes:

I have also tried giving my users, who are assigned to a custom role and are backend users, permissions to edit a page that uses a standard SF template.  They receive the same Sitefinity internal exception when trying to edit a page.

I have also tried upgrading to 4.1.1339.  Same exception.

Hi.  I work w Valerie and we have this update:
We found a sort of work around.  If we put our user in the SF Authors role they can edit the page w o error.
We never had to do this before version 4.1

Before ver 4.1 we had been giving the users role permissions programatically with code like the following, and everything worked fine.

thePermission.GrantActions(true, SecurityConstants.Sets.Pages.Modify);
thePermission.GrantActions(true, SecurityConstants.Sets.Pages.EditContent);
thePermission.GrantActions(true, SecurityConstants.Sets.Pages.Create);
thePermission.GrantActions(true, SecurityConstants.Sets.Pages.CreateChildControls);
thePermission.GrantActions(true, SecurityConstants.Sets.Pages.View);
thePermission.GrantActions(true, SecurityConstants.Sets.Pages.Delete);


So we found a bug in ver 4.1 right?

Hello Phil,

I tried to reproduce your problem, but to no avail. Both with our latest code version and with the build you specified, 4.1.1339.0.

Here's a detailed list of the steps I took:
I created a custom page template in the system, based on a custom master page.
I created a custom page (named "CustomPage") based on the custom template.
I created a custom role (named "PageEditor") in the system, and a user ("testUser") who is assigned to this custom role (and defined as a backend user).
In order to grant PageEditor role specific permissions on CustomPage, I ran the following code:

01.void AddPermissionsToCustomPage()
02.
03.   PageManager pm = PageManager.GetManager();
04.   RoleManager rm = RoleManager.GetManager();
05.    
06.   //get the custom page
07.   PageNode customPage = pm.GetPageNodes()
08.     .Where(
09.       node => node.Title == "CustomPage")
10.       .FirstOrDefault();
11.    
12.   //get the custom role
13.   Role pageEditor = rm.GetRole("PageEditor");
14.    
15.   if (customPage != null)
16.   
17.      //make sure permission inheritance for this page
18.      //is broken. Otherwise specific permissions are
19.      //not effective.
20.      pm.BreakPermiossionsInheritance(customPage);
21.       
22.      //check if a permission for the custom role already
23.      //exists for this page
24.      Permission pageEditorPermission =
25.        customPage.GetActivePermissions()
26.        .Where(permission =>
27.          permission.PrincipalId == pageEditor.Id)
28.        .FirstOrDefault();
29.       
30.      //if the permission doesn't exist,
31.      //we need to created it and attach it to the page
32.      if (pageEditorPermission == null)
33.      
34.         pageEditorPermission = pm
35.           .CreatePermission(
36.              SecurityConstants.Sets.Pages.SetName,
37.              customPage.Id,
38.              pageEditor.Id);
39.          
40.         customPage.Permissions.Add(
41.            pageEditorPermission);
42.      
43.      //grant the custom role the option to modify
44.      //(or any other desired permission)
45.      pageEditorPermission.GrantActions(true,
46.        SecurityConstants.Sets.Pages.EditContent);
47.       
48.      //Done.
49.      pm.SaveChanges();
50.   
51.
Once this code ran, I could verify in the backend UI that my custom role has the correct permissions granted, and editing the page went without crashes while logged in as testUser.

Please let me know if this information was helpful for you. If you still get the errors you reported, please specify in more detail what steps you've taken, the code you've been trying to run in order to grant/deny permissions and the status of permissions on the aforementioned objects.
Thanks.

Kind regards,
