</ol>Looking at "person: Person, op: Person from otherPersonList<span style="white-space: pre-wrap;"></span>", you realize that "person: Person, op: Person" is not a valid CE, not even if you omit the comma Also, the cell cannot end with "from otherPersonList".<br>
<br>A constraint (2 rows down from CONDITION) is expanded with values from cells below it by appending "==" and the cell value.<br><br>Apart from the basic design flaw Greg has pointed out: you can add a from clause by using an additional column with "from otherPersonList<span style="white-space: pre-wrap;">" in the 3rd row after RuleTable and an 'x' in each of the value cells.<br>
<br>You will also have to change the constraint "</span><span style="white-space: pre-wrap;">p</span>erson.getRelationShip(op)<span style="white-space: pre-wrap;"></span> == ..." into an eval since this isn't correct constraint syntax.<br>

<br><br>I suggest that you try and write your rules in DRL first before you start thinking about decision tables. As you can see, certain conditions and CE combinations cannot be expressed in tables. After all, a row of cells is linear, but the syntaxl of LHS expression includes non-linear (recursive) structures.<br>
