Why not put the parameters into a "container" Fact in WM?<br>
<br>
rule "bundle A - included units"<br>
dialect "mvel"<br>
when<br>
Parameters($p1 : param1, $p2 : param2, $p3 : param3)<br>
$order : OrderDTO( )<br>
$line : OrderLineDTO( itemId == $p1, $quantity : quantity ) from<br>
$order.lines<br>
SubscriptionResult( userId == $order.userId, itemId == $p2, subscribed<br>
== true )<br>
$pricing : PricingResult(userId == $order.userId, itemId == $p3)<br>
then<br>
$order.getLines().remove($
<blockquote class="gmail_quote">line);<br>
OrderLineBL.addItem($order, $p3, new Integer($quantity.intValue()),<br>
$pricing.getPrice());update($order);<br>
end<br>

You could load the "Parameter" objects either with a lower salience rule or from Java; both from a database.<br>
<br>
The issues with Guvnor sound like a bug to me and I request you raise a JIRA for investigation.<br>
<br>
Thanks,<br>

It is a Test Code , and i am very new to java and drools<br>
i have a inbuilt<br>
rule "bundle A - included units"<br>
dialect "mvel"<br>
when<br>
$order : OrderDTO( )<br>
$line : OrderLineDTO( itemId == 16, $quantity : quantity ) from<br>
$order.lines<br>
SubscriptionResult( userId == $order.userId, itemId == 12, subscribed ==<br>
true )<br>
$pricing : PricingResult(userId == $order.userId, itemId == 13)<br>
then<br>
$order.getLines().remove($line);<br>
OrderLineBL.addItem($order, 13, new Integer($quantity.intValue()),<br>
$pricing.getPrice());update($order);<br>
end<br>
<br>
i want to modify this rule like<br>
<br>
rule "bundle A - included units"<br>
dialect "mvel"<br>
when<br>
$order : OrderDTO( )<br>
$line : OrderLineDTO( itemId == param1, $quantity : quantity ) from<br>
$order.lines<br>
SubscriptionResult( userId == $order.userId, itemId == param2, subscribed<br>
== true )<br>
$pricing : PricingResult(userId == $order.userId, itemId == param3)<br>
then<br>
$order.getLines().remove($line);<br>
OrderLineBL.addItem($order, param3, new Integer($quantity.intValue()),<br>
$pricing.getPrice());update($order);<br>
end<br>
1.i want to replace hardcoded value to params as ItemId16 to param1<br>
,Itemid12 to param2 so when any one see my rule can not guess about<br>
hardcoded value. and i want that the values of param1,param2 some how come<br>
from database<br>
2.Till now what i did from my reading and exploring is<br>
i have created java functions in jboss which returns value like<br>
GetParam1(some var),GetParam2(some var),GetParam3()<br>
i tested them in jboss drools application they are working fine<br>
3. then i build package and upload in guvnor<br>
4.while writing technical ander Fact field i am getting only GetParam3() not<br>
GetParam1(some var) and<br>
GetParam2(some var)<br>
5. I dont know why . when i remove parameter value say make GetParam1() ,<br>
without parameter it comes under class field.<br>
6. please tell me is it right approach and if right then how i handle<br>
GetParam1(some var) ,because they return param1 value which passed in<br>
modified rule<br>
