DocumentReference fileld null value


I am trying to invoke flow service from trigger service using document reference field.
But when i want to get value from “Integer” field I am getting null value.

Publish document signature consist of String and Integer field;
Trigger service consist of two invoke steps:
- pub.flow:debugLog ( put integer field to log message and get null )
- pub.flow:savePipelineToFile

Pipeline dump file contains number parameter with correct value.

WM version 7.1.2

How can it be?

Thanks in advance.

Hi, again.

Seems like sutiation that I discribe in first post is normal.

There are no Integer in supported Developer types.

Sorry for useless posts.
