DMN13 — How to get FEEL type if evaluation is not an option?

  • Key: DMN13-43
  • Status: open  
  • Source: ACTICO ( Daniel Thanner)
  • Summary:

    in chapter 10.3.2.10: "Sometimes we do not want to evalutate a FEEL expression e, we just want to know the type of e."

    in table 54: column Applicability defines which row in the table to use, depending on the type of a FEEL expression.

    Table 54 only makes sense if it is not allowed to pre-evaluate the expression e2, since even for a pre-evaluation context entries (for example: "item") must be declared in scope.

    How do we know the type of a FEEL expression if it is not allowed to evaluate it?

    Examples:

    • [1,2,3][min(3,2,1)]
    • {a:function() external {java: {class: "clazz", method signature: "method()"}}, b:[1,2,3][a()]}.b
    • {a: 1, b: a instance of number, c: [1,2,3][b] }
