Drools decision tables -- calling functions inside value cells

I am looking to use drools decision tables for a project. I want to add a condition where I verify that the value of a passed in object is less than a specified number. I want the decision table to look something like:

If you look at the third condition where I am checking the max size of the loan, I am calling a function: $t.getStandardLimit($n).

Unfortunately, I am unable to call the function inside the value cells with that syntax (drools reads it as a string and returns a syntax error). Is there a way to do this?

UPDATE: The solution was to add $param in the condition check (loanAmount <= $param)

Solution

  • Have not actually tested it but I think it may work:

    for the Max loan condition, change it to loanAmount <= $param.

    If loanAmount is of type integer or double etc, it should work without problem because, after subtituting $param, both loanAmount <= $t.getStandardLimit($n) and loanAmount <= 1000000 is a valid expression.
