I am trying to leverage a Choice with Alias (multiple) User Parameter in a custom transformer. When I add the custom transformer to a new/blank workbench and connect it to an data input (CSV), all the attributes also show up for the user to choose from. Am I missing a setting/toggle somewhere?

 

Parameter Setup:

 

What's showing up when custom transformer is added to an empty/new workbench and connected to a CSV input:

 

Why are these attributes from the input showing up in Choice parameter? If I select Choice with Alias without multiple choice, it works properly.

FME 2018.1.1.2 (Build 18586)

 

Thanks.

It seems that a parameter with Choice (Multiple) and Choice with Alias (Multiple) type accepts feature attribute value(s) by default. If you don't want accept attributes, set Off to the Attribute Assignment parameter in the parameter definition.

I figured it was something simple. Thanks @takashi!
