Changing the name of a Pie Graph causes error

[James]

I am new to Telerik and have run into an issue with the creation of a Pie chart.  I first set my data source groups and run the design mode view to see that the graph looks correct.  I then go to start cleaning things up and rename the graph from graph1 to another name and then run the designer view again to see the error :

An error has occurred while processing Graph 'DeviceTypePercentages':

An error has occurred while processing RangePolarDataPoint:

Scope name 'graph1' does not represent a valid data scope name.

---------InnerException--------

Scope name 'graph1' does not represent a valid data scope name.

Thanks for any help you can provide on this.

Hello James,

I suspect that you have used the scope of the graph in an Expression before renaming the graph. Note that the data scope is represented with the name of the corresponding data item provided as a string. Hence, after renaming the graph it will be necessary to modify also its scope name in all the Expressions where it is used. In the particular error the expression should be searched for in RangePolarDataPoint.

Neli,

I never found a "RangePolarDataPoint" value in the pie chart but I did find the second instance of the variable being used and changed it as well and now I do not receive the error anymore.  

Thanks

Where was the second instance of the variable? I am having the same issue

Manuel, please attach a trace listener to the standalone designer and send us the generated log - Standalone Report Designer Problems.

Also, please attach the report in question, alongside some sample data, to your next reply and we will inspect it.
