Hi, Would it be possible to write a custom expression modifier that would emulate this behaviour. So a modifier that would return 'false' for the following expression: null | false | true I'm having problems getting this to work, especially since it would have to work for an expression like the following too. Which I would like to return false(the 5th in the chain): object/callMethodForNonExistingObject | array/elementNotSet | array/ elementIsNull | object/returnsNull | object/returnsFalse | default I've tried for hours now, but can't seem to get a working solution.
