> the expression `addend + listOfStructure[field1="some value"].numberField`, where `field1="some value"` filters `listOfStructure` to a single item and `addend` and `numberField` are both non-null numbers, fails to evaluate. It's possible to work around this by placing `listOfStructure[field1="some value"]` into a separate decision.
