<DIV></DIV>But then that would call the service.getType() method when the rule

use a rule to set the value within another rule? <BR>-> I am not sure that

at rule execution, then you would need to add an attribute name to your
object, and call getType() before creating the rules. <BR><BR>Alternatively,
you can insert an intermediate value whose value will be set by another rule
and then use this intermediate value in your DC rules. <BR><BR>When

<BR>insert(name); <BR><BR>Something like this... but make sure not to create a

<BR><BR><BR>Hi, <BR><BR>The way I see it, this is the way your template
should look like. I do <BR>not see the need to use eval() at all.
<BR><BR>rule "DC_0" <BR>when <BR>Â Â $service: Service(name ==
"@{service}", value == "@{value}") <BR>Â Â $riskType: RiskType()
<BR>then <BR>Â Â
$riskType.setName($service.getType("@{value}")); <BR>Â Â
$riskType.setAtt(0,"@{value}"); <BR>end <BR><BR>I am assuming that RiskType
is already inserted in WM, but you could <BR>just as well create a new
object in the then-part of the rule. <BR><BR>In stead of using the
java-function to determine the name, you might <BR>actually just as well
create an other rule that sets the name according <BR>to the value, thus
putting the entire decision logic in rules. <BR><BR>Hope this helps.

  <BR>     I'm trying to get
a template (.drt) to generate 2 rules (.drl) <BR>from 2 datasets but by
doing a little bit more work than direct <BR>substitution. <BR>Â
   <BR>    Data
(service,value): <BR>Â Â Â Â DC, AAA <BR>Â
   DC, XYZ <BR>   Â
<BR>Â Â Â Â Idea for the template - if value is of
type1 then create Type <BR>object with 'Type1' as name. If value is of
type2, use 'Type2' as name: <BR>Â Â Â Â <BR>Â
   rule "DC_@{row.rowNumber}" <BR> Â
  when <BR>     Â
Service(name == "DC") Â Â <BR>Â Â Â Â
then <BR>Â Â Â Â Â Â
Type.setName(eval(Service.getType(@{value}))) <BR>Â Â Â
   Type.setAtt(0,@{value}) <BR>  Â
 end template <BR>    <BR> Â
  eval(Service.getType(@{arg0})) should take 'AAA' or 'XYZ'
etc as <BR>arg and return a string Type1/Type2 etc. <BR>Â Â
  <BR>    This would then generate
2 rules that look like: <BR>Â Â Â Â <BR>Â
   rule "DC_0" <BR>    when
<BR>Â Â Â Â Â Â Service(name == "DC",
value == "AAA") Â Â <BR>Â Â Â Â then
<BR>Â Â Â Â Â Â
RiskType.setName("Type1") <BR>Â Â Â Â Â
 RiskType.setAtt(0,"AAA") <BR>   Â
<BR>Â Â Â Â rule "DC_1" <BR>Â Â Â
 when <BR>     Â
Service(name == "DC", value == "XYZ") Â Â <BR>Â Â
  then <BR>     Â
RiskType.setName("Type2") <BR>Â Â Â Â Â
 RiskType.setAtt(0,"XYZ") <BR>   Â
<BR>Â Â Â Â ...is this possible at all? I'm trying
to avoid the eval step <BR>being done in the actual rule (.drl) .
<BR>Â Â Â Â <BR>Â Â Â Â
Thanks <BR>Â Â Â Â <BR>Â Â Â
