The problem is RULE2 does not create a Customer pattern as you do not specify at least one constraint.<br><br><span style="font-family:courier new,monospace">               CONDITION         CONDITION         ACTION</span><br style="font-family:courier new,monospace">

<br>
my spreedsheet received 4 facts. I need all of them to check conditions but<br>
not all of them are used in all rules. There are some rules that modify a<br>
fact which is not used in any of the conditions and thus, it is not<br>
&quot;declared&quot; on the left side of the rule.<br>
<br>
Let me show you an example:<br>
<br>
                    CONDITION         CONDITION         ACTION<br>
                    Customer c           Tariff t<br>
                    name                     value<br>
customer.setOffer($param)<br>
<br>
RULE1         &quot;pepe&quot;                    5                         &quot;lot of<br>
offers&quot;<br>
RULE2                                      100                      &quot;lot of<br>
offers&quot;<br>
<br>
When I try to compile this, I get a compilation error:<br>
<br>
[ERROR] | 2012-03-14 17:21:30,238 |<br>
es....ruleengine.impl.RuleEngineUpgradeImpl[RuleEngineUpgradeImpl.java:117]<br>
| Rule Compilation error customer cannot be resolved<br>
customer cannot be resolved<br>
<br>
Any suggestion please?<br>
Thanks,<br>
