Hi,
I get "object reference not set to an instance of an object" for some charts in a report.
Software: SQL Server 2008 R2 SP2 & SharePoint 2010
I have 2 reports each with multiple graphs & tables. The reports are used in SharePoint integrated mode.
3 months back Report1 gave the error for 4 specific charts. After a few days, the error vanished magically & all charts displayed correctly.
I recently deployed Report2 which also contains charts & tables. After a few days, the 1st chart itself would not display throwing this error. I deleted the Report2 from SharePoint and redeployed it. Now the error is shown for 2 charts in between & I again see the error for the same 4 charts of Report1.
Since deleting and redeploying the Report2, moved the error to a different chart, it does not look like a problem with the chart itself. Please suggest on what I can do further.
