'PropertyValue' attribute usage


How do you specify a property when using PropertyValue attribute ? 

for example, when we have 2 attributes, A and B

how do we specify that we want to use the PropertyValue of property A ? 

I tried


but it did not work

Not sure I understand the question, which processor/property are you taking about? Basically if you want to access a flowfile attribute value in expression language you can use ${A} in case you have an attribute called A
