Setting adjust pages in omnigraffle
 

Hi!
I fail in setting adjust pages for a new document. Tried to set it in the properties, the dictionary says: canvas: adjust pages(boolean), but I get syntax error at:

set properties of first canvas of front window to {adjust pages:true, ..


Also tried telling the canvas at the end:
tell canvas of front window
page adjust

but that does not do anything, seems ignored.
The attached script has the page adjust at the end since I could not get it to compile setting it in properties.

Thanks for any hints!
