Issue upgrading from Q2 SP1 to Q3

[B]

I've got a report with multiple tables in it.  It's worked perfectly in v Q2 2010.

I just upgraded to Q3 2010 Reporting and now get the following table errors on multple tables (some table render fine, others return the following error:

(the table is displayed as a red box with the following error)

An error has occured while processing Table 'table 10':
Group with name 'Group6' already exists.  Groups should have unique names.

I followed the upgrade instructions for major release.  Everything else seems to be working fine, except the error above.  Any suggestions? Thanks in advance.

The same problem happened to me after the update

Hi guys,

We were able to narrow down a case in which this problem occurs i.e. you have named a TableGroup with the following naming convention: GroupX where X is number. Please check your report for such occurrences and rename them to something more distinct, while we would address this case for subsequent service pack.
If this is not the case, we would appreciate if you provide us with a sample report that exhibits the problem and we would advise you accordingly once we review it.

Sincerely yours,
Steve

I havent' named any of the table groups.  I think your designer is doing that automatically.  During report contruction, i created the first table and then copied and pasted to create the other tables.  In the Report.Designer.cs file the offending line of code is similar to the liine below for each table that won't render:

tableGroup112.Name = "Group2";

Please keep in mind the report compiles successfully, but the error is returned during report generation.  I found a quick fix was to delete each line (similar to above) for each table that wasn't rendering.  Once I did that, everything is working fine.

One other note, i don't use grouping in any of the tables, so i deleted the groups in the report designer.  Maybe the designer isn't cleaning up the code in the Report.Designer.cs?

Hi B,

The actual problem is that the designer did not assign a name for every single table group. If this was true, then we would not generate tablegroup names in runtime that would match the hardcoded existing values.
Either way, we would fix this problem in subsequent internal build.

Your Telerik points have been upgraded for bringing this to our attention.

All the best,

I just had exactly the same problem. Deleting the Group name assignments worked perfectly. Thanks for the fix.

Dear Steve,

I Tried to upgrade my telerik reporting from Q1 2010 to Q3 2012 but the problem still exist.. Should i upgrade my telerik reporting to Q3 2010 first ? 

 If I should upgrade from Q3 2010 first, how can i get that version because  in My account panel, The older version telerik only shows the older version from Q3 2012.to Q2 2013 SP1

 for your information, I buy the program that use telerik reporting Q1 2010, and i start Purchase the telerik license in 2012, Maybe that the caused the older version before 2012 not showing in my account

Hello Ronald,

You do not need to upgrade to Q3 2010, as the Q3 2012 version contains the fixes from older versions. Please open a new support ticket and provide the problematic report for further investigation. We will review it and advise accordingly.
