> When creating rules in guided editor, we are running into validation errors depending on the order of the conditions. The problem is that the order of the conditions is important:
> {noformat}
> when
>   COND_X
>   COND_Y   => works
> when
>   COND_Y
>   COND_X   => fails
> java.lang.AssertionError: [10,18]: [ERR 101] Line 10:18 no viable alternative at input 'Number' in rule "ATO_Negative_AU_Test"
> [0,0]: Parser returned a null Package
> {noformat}
> Test cases showing the compilation failures (@Test testOrder1 vs
> testOrder2) can be found here:
