System.NullReferenceException on any Export Wizard


#1

Howdy,

In 5.5.0.217, any time I try the Export Wizard to export to Excel, I get
this after the column selection screen:

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

Anyone else getting this? As a workaround, the Quick Export seems to be
working just fine.

Hi Rich,

I’ve just tried to export some table to Excel – worked fine for me.
What are exact steps you’re doing while exporting? Any additional info
would be highly appreciated.

Thanks,

Igor.
