I'm working on an expression rule that takes two inputs: an integer value (fieldname is key), and a CDT array (AnyType) where one of the fields I want to search on is named Key..so MyCDT.Key. The expression rule is actually more complex then this but to isolate my issue I am giving only the specifics here. Anyhow, here is the rule:

= load(
wherecontains(
ri!key,
ri!MyCDT.Key
)
)

I'm getting the following error:
"There was an error testing the rule:
Expression evaluation error at function 'wherecontains' parameter 2 [line 2]:"

I'm pretty certain this has to do with the fact that something is lost in passing something over to the expression rule--that it has no clue what this AnyType is. Perhaps I need to do an explicit cast of my AnyType into a CDT array?

I believe your issue stems from the fact that you are passing in an array of CDTs; therefore, ri!myCDT.key is one level above the value for which you are actually looking. Try indexing one more level down, like this:

fn!wherecontains(
ri!key,
fn!apply(
fn!index(_, "key", ""),
ri!myCDT
)
)
