 Q:

Java EL expressions: "property (num1|str) not readable on type (int|String)"

I am trying to use EL expressions to create a predicate for filtering arbitrary objects using provided strings to describe the filter. It works for primitive types, but for some reason it tries to access the POJOs I supply as if they were the type they were trying to receive.
