Hello Dmitry:

You can use e() function from nfTools to greatly simplify the
parameter object creation, like this:

* using nfTools:

oParameter = e('attachment(2)',m.doc1,m.doc2,'count',2)

* instead of :

oParameter = create('empty')
addProperty(oParameter,'attachment(2)')
oParameter.attachment(1) = m.doc1
oParameter.attachment(2) = m.doc2
addProperty(oParameter,'count',2)
