Advanced Attribute Update using Parameter Context Reference

[#1]

Hello Community,

I can assign an attribute's value using a reference to a parameter context value ( e.g. #{variablle_abc} ).

But when I attempt to do this same thing within the "Advanced" window in an UpdateAttribute processor, it fails.  I've verified the Process Group Parameter Context is set.  

Anyone know how to make this work in the Advanced window of an UpdateAttribute processor?

I managed to get it working by putting the parameter context reference in quotes and then using an evaluateString() function as shown below.

${#{'Entity Service'}:evaluateELString()}
