strange behavior of replace tokens operator

simon_knoll

hello all,

im having a workflow containing a create document operator and a process documents operator.
the process documents operator entails a tokenizer and a replace tokens operator.
the replace tokens operator has following rules.

replace est with Eastern_Time
replace dup with duplicates
and hello with hallo

the process documents vector creation is set to term occourences.

the create documents text is :

est
dup
hello

the created wordvector eintails now
Eastern_Time
duplicate
hallo

and now comes the strange thing:
Eastern_Time and duplicate have occourence 0 and hallo has occourence 1

i expected a vector where every of the terms has occourence 1

if im exchanging the process documents operator with the process documents from files operator and i write the words 

est
dup
hello

in a text file i get the expected beavior with a vector entailing

Eastern_Time
duplicate
hallo

and every term has an occourence of 1

is this a bug?
am i doing something wrong?

all the best
simon

Hi,
thanks for this detailed report. I have found the problem: The Documents delivered to the input ports were directly delivered to the inner process. Since the inner process is passed twice by each document, they where tokenized and replaced two times. Make a break point before the tokenize operator to see this effect.
I have corrected this, it will be delivered with the next regular update.

Greetings,
  Sebastian
