Steema Central

We use:
TeeChart
Latest Binary version: 28th May 2009 Framework 2.0 Build 4.0.2009.21354

We use the Export dialog to give the user the option to export the Chart as picture.

On some machines the following happens:
If I select the last export option "as Flex", an exception is thrown (direct after the selection of this node).
This happens on 2 machines without dev environment.

************** Exception Text **************

System.NullReferenceException: Object reference not set to an instance of an object.

Hi ATV,

This is probably because you don't have the Flex compiler installed on those machines and therefore Flex exporting doesn't work. Please read this post on how this should be set.

Hope this helps!

Normally I would excpect, that the TeeChart LIB handles this problems internally - without the need to make a bugfix around ...
The enduser should not see any exception ...

Hi ATV,

Ok, I have added this to the list to be implemented for next releases.

Thank you ...
