We have been using Infragistics 2006v1 for a few years without any issues. We recently renewed and updated our site to Infragistics 2009v2. After a day or so of uptime on our production server we start getting random exceptions with the infragistics controls. The exact exception that start it off is below. The only way to fix this is to do an IIS reset and then it will be stable for a day or so.
** Exception : Object reference not set to an instance of an object.
** Stack Trace : at
Infragistics.WebUI.Shared.GlobalCssHelper.GetPageContainer(Page page, Boolean create)
control, Page page)

Thank you for a report.That issue was introduced around 7-8 months ago due to work around memory leaks on server which occurred in some specific applications. Around 2 months ago, that was reviewed and current version uses different logic. Particularly the GlobalCssHelper class which was used in earlier versions before AppStyling, was deprecated and removed from logic.
Please get latest service release, it should not have that issue.
We are using the latest version 2009 v2 that came out recently is there a way we are using the legacy controls or a service pack we are missing?
I checked source codes and found that that fix did not go to the RELEASE build yet. I hope, that will be available in coming service releases.
Thank you for your help. Is this true for both 2009v1 and 2009v2?
Actually currently source codes for RELEASE of 9.1 and 8.3 contains fixed version. Codes were merged with DEV on 10/26/2009 and version 9.1.20091.2113 was built on 10/27/2009. I expect that public dlls for 9.1/8.3 already contain that.
