Hello-

I'm interested in seeing the potential from using Nevron Chart for Sharepoint but I'm having all kinds of problems right off the bat.  My problems are the following -

The documentation for installation is mis-leading in that it makes it seem that if you use the Sharepoint Registration Tool you should be set, no additional work required

This doesn't seem to be the case as I've done this tool with no errors whatsoever.  However, when I attempt to add the Web part to a WSS page, click the Chart Designer I get access denied.  I'm the Farm administrator and also a Windows local admin.  What gives?

I've searched everywhere and my problem must be unique.  Any guidance would be greatly appreciated!

Thanks,

-Chris

Hello Chris,

 

Thank you for your interest in Nevron Chart for SharePoint.

We understood that you have successfully installed, registered and run the chart examples locally. However, you are receiving the “Access Denied” error when you try to use the Chart webpart on the WSS page you are working on. Can you please provide us with more details regarding your scenario and configurations.

 

We have tested the Chart with WSS and everything is working properly, your issue may be related to administrative rights. By default the share point installer will give access rights to the following accounts:  WSS_WPG, WSS_RESTRICTED_WPG, WSS_ADMIN_WPG. Please check if these three accounts have read, write and browse folder contents permissions for the:

C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\LAYOUTS\Nevron\Chart\Temp

and

C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\LAYOUTS\Nevron\Chart\State

directories.

 

You can also test to check if the problem is caused by access to one of these directories by temporarily granting full access to the “everyone” account for them.

 

Looking forward to hearing from you.

 

Regards,

Nevron Support Team

Best Regards,
Nevron Support Team

Hello,

Sorry, but this didn't resolve the problem.  The URL (which isn't helpful probably) though is giving the error is the following -

http%3A%2F%2FWSSServerName%2F%5Flayouts%2FNevron%2FChart%2FNChartDesignerPage%2Easpx%3FWebPartId%3Dg%5F850604f3%5F70fa%5F4d79%5F8781%5F5255ccdaa47a

Anything else I might try?

Thanks,

-Chris

Hello Chris,

 

We are glad that we were able to contact you directly and we will do our best to assist you.

Last 2 days we've tested several case scenarios with clean installs:

 

1. Windows Server 2003/IIS6/SQL Server 2005/Team Foundation Server 2008/SharePoint Services

2. Windows Server 2003/IIS6/SQL Server 2008/Team Foundation Server 2008 - SP1/SharePoint Services

3. Windows Server 2008/IIS7/SQL Server 2008/Team Foundation Server 2008 - SP1/SharePoint Services

 

We have tested our web part in sites created by Team Foundation Server automatically and also in sites created by SharePoint Services Web Administration. We were not able to reproduce the problem.

 

We recommend you to try to unregister and register again our web part with Nevron SharePoint Registrator which you can find in our installation folder in program files or in Start -> Programs -> Nevron SharePoint Vision 2009.2.

 

You can also try to enable SharePoint Trace for debugging. For the purpose go to installation folder of the SharePoint site usually at c:\inetpub\wwwroot\virtualdirectories\sitefolder, open web config and set CallStact to true - <SafeMode MaxControls="50" CallStack="true"/> also set customErrors mode to remote only - <customErrors mode="RemoteOnly" />

 

Another idea is to try to remove the call to our dll in NChartDesignerPage.aspx (<%@ Register Assembly="Nevron.Chart.SharePoint.Design....) just for testing purpose if the security problem is with our dll in gac. You can find NChartDesignerPage.aspx in: C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\LAYOUTS\Nevron\Chart.

 

Your feedback will be greatly appreciated. We will do our best to provide you with extended tech support and a great charting solution for the SharePoint environment.

 

We are now finalizing the next major release of the SharePoint Vision suite, which will include Gauge support and other new features (like code embedding).

 

Kind regards,

Nevron Support Team

Best Regards,
Nevron Support Team

Hello-

I played with this over the weekend with the same results.  I believe that, somehow, I've got an issue with the designer page.  I noticed when I opened up the designer page in Visual Studio it mentioned that the code behind file was missing -

CodeBehind="NChartDesignerPage.aspx.cs"

<%@ Page

Language="C#"

AutoEventWireup="true"

CodeBehind="NChartDesignerPage.aspx.cs"

Inherits="Nevron.Chart.SharePoint.Design.NChartDesignerPage,Nevron.Chart.SharePoint.Design,Version=9.12.2.12,Culture=neutral,PublicKeyToken=a569cfe19372196c" %>

Where is the NChart designer code behind file?

-Chris

Hi Chris,

The code behind is just a C# class that is compiled in the Nevron.Chart.SharePoint.Design.dll assembly. IIS will automatically create an instance of this class when it loads the aspx.

We are positive that the installation problem that you experience is related to security and/or the environment in which you try to run the chart designer. Unfortunately we were not able to reproduce the error on the test environment that we have made - the chart installed and was flawlessly editable.

Have you tried to insert any other third party web parts? Are they operating without problems?

Best regards,
Ivo

We are getting the same Access Denied error when we click on Run Chart Designer (Windows Server 2003, WSS 3.0 only (no MOSS), SQL Server 2005 with IE 6.0 at client workstations on Windows XP Pro).

To reproduce it within your labs, try creating a new Sharepoint App with no collection at the root. Then create a collection under /sites/whatever and install your package.

Because there is no access at the root of the app, every user will be getting an access denied message when clicking on your Run Chart Designer button.

We don't give any rights at the root level of our Sharepoint apps over here and your products seems to require it to work.

Pierre
