I'm trying to use a string that contains 

$()


 (dollar, left parenthesis, right paranthesis) via a published parameter in a HTTPCaller.

I'm having trouble using a text/string like that because, depending on the transformers used,

  • either the part "$()" simply disappears, or
  • FME throws an error: "Undefined macro `' dereferenced"

I tried to create a feature using the PythonCreator and also Creator + AttributeCreator, however both fail with the error mentioned above. Screenshot of my test workspace:

I thought about escaping the string but that didn't work either (no error, but backslashes "\" remain in the text):

\$()
\$\(\)

What is the right encoding or escaping sequence here? 

I tested FME Desktop 2015.1 and 2016.0. 

This worked (but is not the nicest solution):

Hi @chk1, try changing the parameter type to Text (Mutiline).

Hi @chk1, try changing the parameter type to Text (Mutiline).

oops, the workaround using Text (Multiline) type parameter seems to be available in FME 2016.1 or later. In 2016.0 and earlier, a Text (Multiline) type parameter causes the error too...
