I can not change attributes of a form during the document posting

Aho!

I'm changin the an attribute of the document form during posting to display the posting result, but now I receive the following message: "Data has been changed. Do you want to save changes?" and when I choose Save the document is posted again. Is it possible to perform this programmatically not to make a user click save twice?

You can change form's property Modified to False at AfterWrite event handler of form.

&AtClient
Procedure AfterWrite(WriteParameters)
   Modified = False;
EndProcedure

Thank you again, Ivan!
