The action is not being executed. I don't use decision tables
frequently, but I think that it ignores empty cells and is generating an
empty consequence for your rule. Usually, you would place the method call on
the header prototype and the parameter in the cell. So your cell would be:
| hoover | true |
| xyz | false |
The method prototype would be something like (please check the correct
syntax in the manual):
brand.setGoodBrand( $param );
Where the engine would replace $param by the value you write in the
cell.
