Web Parts Installation

Hey Guys,

I'm trying to install QV Web Parts for Sharepoint but I'm coming across this error. I have completed part 1 through 5 from

http://community.qlik.com/wikis/qvwebparts9/default.aspx

Restarted IIS and the server and still got the error. When I convert back to the old web.config file sharepoint works again.

Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".

<!-- Web.Config Configuration File --><configuration> <system.web> <customErrors mode="Off"/> </system.web></configuration>

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

<!-- Web.Config Configuration File --><configuration> <system.web> <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/> </system.web></configuration>

Server Error in '/' Application.

Hi Kristen,

Did you manage to find a solution to this problem?

Only I am also attempting to install the "QV Web Parts for Sharepoint" and have come across the same (or similar) problem.

Have followed the "installation guide", but am receiving the following error:

Server Error in '/' Application.

Security Exception

Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: Request for the permission of type 'Microsoft.SharePoint.Security.SharePointPermission, Microsoft.SharePoint.Security, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' failed.

Stack Trace:

[SecurityException: Request for the permission of type 'Microsoft.SharePoint.Security.SharePointPermission, Microsoft.SharePoint.Security, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' failed.] Microsoft.SharePoint.WebControls.TemplateBasedControl.get_Controls() +39 QT.QWW.Support.QvDataSourceFinder.findDataSourceByID(String qvDataSourceId, Control control) +606 QT.QWW.Support.QvDataSourceFinder.findDataSourceByID(String qvDataSourceId, Control control) +680 QT.QWW.Support.QvDataSourceFinder.findDataSourceByID(String qvDataSourceId, Control control) +680 QT.QWW.Support.QvDataSourceFinder.findDataSourceByID(String qvDataSourceId, Control control) +680 QT.QWW.Support.QvDataSourceFinder.findDataSourceByID(String qvDataSourceId, Control control) +680 QT.QWW.Support.QvDataSourceFinder.findDataSourceByID(String qvDataSourceId, Control control) +680 QT.QWW.Support.QvDataSourceFinder.FindDataSourceByID(Control controlStart, String id) +457 QT.QWW.WebControls.QvObjectBase.discoverDataSource() +78 QT.QWW.WebControls.QvObjectBase.RegisterStyleSheetInInHeader() +29 QT.QWW.WebControls.QvObjectBase.OnPreRender(EventArgs e) +24 System.Web.UI.Control.PreRenderRecursiveInternal() +108 System.Web.UI.Control.PreRenderRecursiveInternal() +224 System.Web.UI.Control.PreRenderRecursiveInternal() +224 System.Web.UI.Control.PreRenderRecursiveInternal() +224 System.Web.UI.Control.PreRenderRecursiveInternal() +224 System.Web.UI.Control.PreRenderRecursiveInternal() +224 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +11035559 System.Web.UI.Page.ProcessRequest(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +11035098 System.Web.UI.Page.ProcessRequest() +91 System.Web.UI.Page.ProcessRequest(HttpContext context) +240 ASP.WELCOMELINKS_ASPX__1240452380.ProcessRequest(HttpContext context) +9 Microsoft.SharePoint.Publishing.TemplateRedirectionPage.ProcessRequest(HttpContext context) +283 System.Web.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +599 System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +171

The problem appears to be related to the "SharePoint trust/security policy settings" detailed in step 4)

Changing the "Trust level" to "Full" (<trust level="Full" originUrl="" />) does prevent the error, but obviously leaving the config in "Full Trust Mode" isn't really an option for a production environment.

Hey AObi,

I haven't been able to fix mine yet.

I did notice on the trust setting to make sure the PublicKeyBlob runs on one line with no new lines (no enters).

Thanks for the suggestion Kristen,

But unfortunately that's not the problem (already made sure PublicKeyBlob is on one line).

The problem appears to be due the CAS (Code Access Security) Security Policy is not getting referenced / picked up correctly.

Hey Guys,

If you come across this error first you must find out what the true error is. Open the web.config file and change On to Off like below. Don't foreget to change back when your done!

And changing it to:

This should result in more useful information in diagnosing the problem.

Your error is most likely due to wrong settings in the policy file. I guess everything works fine if you set the trust to Full? If yes, focus on the policy file created. Please find attached an example policy file for reference.

Thanks Bjorn,

Think I have also identified the cause of the problem...

The CodeGroup detailed in the installation documentation (http://community.qlik.com/wikis/qvwebparts9/part-4-sharepoint-trust-settings.aspx) is different / incorrect....

</CodeGroup>

Where as yours is...
