--------------------------------------

             Summary: Execute a Table with multiple input can cause NullPointerException
                 Key: DROOLS-5102
                 URL: https://issues.redhat.com/browse/DROOLS-5102
             Project: Drools
          Issue Type: Feature Request
    Affects Versions: 7.33.0.Final
            Reporter: Eugenio Romano
            Assignee: Mario Fusco
         Attachments: different-all.dmn

If you execute the DMN table in attach in the last version you will have a NullPointerException in case your input value is not matching any output.
We are moving from version 23 to 33 and one of our tests are catching this issue

The ProcessedExpression Class seems can be responsible of causing this NullPointerException.

{code:java}
this.ast = (BaseNode)tree.accept(new ASTBuilderVisitor(ctx.getInputVariableTypes(), ctx.getFEELFeelTypeRegistry()))
{code}

If you try with 

"inputString", "hi"
"inputInteger", 12
"inputBoolean", false
"inputDate", "2019-09-26T00:00:00.000+0000"

you can replicate the error
