Limiting Available Literal Values, Variables, and Operators
One important concept to remember about Expression Editor Assistant is how it limits the available literal values, variables, and operators to those that are valid for the expected type. For example, if you open Expression Editor Assistant for a string input parameter, only string literal values, string variables, and operators that produce strings are available. Similarly, when you have selected an operand in an operator, the only available literal values, variables, and operators are those that are valid for that operand type.
