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

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