<DIV></DIV>But then that would call the service.getType() method when the rule
is <BR>run wouldn't it? <BR>-> Yes <BR> <BR>I'm trying create explicit,
simple rules to avoid doing extra work when <BR>running data through them.
<BR>-> OK, in essence, I like that :-) <BR> <BR>How would you use a
rule to set the value within another rule? <BR>-> I am not sure that I follow
you here... <BR>If you want to avoid to execute the getType()-service 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>Service(value = "AAA")
<BR>Then <BR>String name = "Type1"; <BR>insert(name); <BR><BR>Something like
this... but make sure not to create a loop :-) <BR><BR>Regards, <BR>Frank

<BR><BR><BR>Hi, <BR><BR>The way I see it, this is the way your template should

Hi, <BR> <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> <BR>
Data (service,value): <BR> DC, AAA
<BR> DC, XYZ <BR>
<BR> 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> <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
<BR>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 <BR>being done in the actual rule (.drl) . <BR>
<BR> Thanks <BR>
<BR> Chris
