If input value is NULL (""), then the result will be TRUE or FALSE?

[sgfromu]

Hi, please tell me if the condition in the DMN is <10, and the input value is NULL (“”), then the result will be TRUE or FALSE?

Can you explain a little more clearly what exactly the expected inputs, outputs and result you’re interested in getting.

@Niall

Can you explain a little more clearly what exactly the expected inputs, outputs and result you’re interested in getting.

I want to understand if the first condition will work if the input variable “number of people” is null

Hi @sgfromu,

The below docs might be of help to you
https://docs.camunda.io/docs/components/modeler/feel/language-guide/feel-error-handling/#handle-null-values

For instance, if the expression (? = null or ? < 10) is used in the DMN table, the first rule should be selected if the input is null.

get-or-elsevalue-default can be used
