Hi,

We are facing issues while exporting charts containing more than one measure in PDF format. The bug is reproducible with the same exception/error thrown each time that that action is taken by the end user.
(Export of the same charts (containing more than one measure) in other formats (such as JPEG, PNG, etc) works fine.)

Here are the error/exception details:

Yes please - would you be so kind as to give us some code with which we can reproduce this issue here?
