tables<o:p></o:p></span></p>

<p class=MsoNormal>Hi All,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I wanted to throw to discussion a feature that might be good
in Drools. I am basically trying to model a formula evaluator in a decision
table. The idea being that a business user directly defines formulas(without having
to use Guided Editors in the BRMS or Eclipse, as business users love Excel more
than anything else..;)).<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The thing I am trying to do is the following:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Condition
Action<o:p></o:p></p>
<p class=MsoNormal>T:FormulaFact<o:p></o:p></p>
<p class=MsoNormal>formulaName
int salary=t.getSalary();<o:p></o:p></p>
<p class=MsoNormal>
t.setBenefit($1);<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Formula1
salary * 100<o:p></o:p></p>
<p class=MsoNormal>Formula2
salary * 1000 <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Everything runs great as Excel simply substitutes the
entered string into the function. The problem I face is when I write something
like this:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Formula3
min(salary,100) <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The ”,” here is treated as the delimited of a
parameter. So the compiled DRL does not set the string correctly. It would make
a rule like<o:p></o:p></p>
<p class=MsoNormal>Rule FormulaTable_123<o:p></o:p></p>
<p class=MsoNormal>When<o:p></o:p></p>
<p class=MsoNormal>T: FormulaFact(formulaName=”Formula1”)<o:p></o:p></p>
<p class=MsoNormal>Then<o:p></o:p></p>
<p class=MsoNormal>int salary=t.getSalary();<o:p></o:p></p>
<p class=MsoNormal>t.setBenefit(min(salary); //Since the words after the
, become part of $2 which is not defined.<o:p></o:p></p>
<p class=MsoNormal>End<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Is there any-way to declaratively change the Decision Table
Parser to not use , for delimiting between parameters and use some other
character.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I could always write the DT using my character, then compile
the DT into DRL and replace my character with ,(I am thinking of using
“Colon”), but would it be a good idea to have an Excel or a Property File
that can be read by the SpreadSheetCompiler to change the delimited character
used by the Parser.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Cheers,<o:p></o:p></p>
