What is the way to show "not equal" in Camunda DMN?

I have an if-else condition for Camunda DMN:

if(x = 0) {
   z = 0;
} else {
   if(y = 0) {
      z = 1;
   } else {
      z = 2;
   }
}

I have this in Camunda table:

     Input      |     Output
----------------------------------
  x    |    y   |        z
----------------------------------
  0    |    -   |        0
 !=0   |    0   |        1
 !=0   |   !=0  |        2

My "Hit Policy" is "First" but I'm getting an error of "Syntax error '!=0'" when running a unit test on Java on it.

Cell Expression Language is 'feel'.

What is the way to show "not equal" in Camunda DMN?

Solution

  • in DMN standard FEEL language, the unary test for "not zero" is:

    not(0)
