PDF Export Empty (0 Bytes)

[André]

Hey out there,

currently we try to switch our Grid (old Telerik Grid)  and its functionality to the Kendo Grid.. Everythings works pretty fine except PDF export.

This snippet demonstrates the way the grid is embedded. Excel Export works fine. PDF Export returns empty pdf file. If I force proxy I get the following error:

n caught TypeError: t.split is not a function

    at n (kendo.all.js:3292)

If I don't use a proxy I get an empty file and no action seems to get called.

Whats the secret? Thanks in advance..
