[jboss-jira] [JBoss JIRA] Resolved: (JBRULES-2344) Pattern analysis can never be satisfied, however the rule is logically correct

Pattern analysis can never be satisfied, however the rule is logically correct ------------------------------------------------------------------------------ Key: JBRULES-2344 URL: https://jira.jboss.org/browse/JBRULES-2344 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-verifier Affects Versions: 5.0.1.FINAL Environment: MacBook Pro 17" Core 2 Duo Ubuntu 9.10 64bit (native, not virtualized) - Apache Tomcat 6.0.18 - Java 6 Reporter: Claudio Gargiulo Assignee: Toni Rikkola Fix For: 5.1.0.CR1 When I launch the analysis of a rule I get the following message: Pattern, name: TrafficoEntrata in Rule 'backToNormal' can never be satisfied. Pattern, name: StatoRete in Rule 'backToNormal' can never be satisfied. The Rule "backToNormal" is the following: rule "backToNormal" dialect "mvel" when exists Attacco( ) attack : Attacco( ) StatoRete( numero_utenti > "25" && < "80" ) TrafficoEntrata( banda_occupata > "20" && < "80" ) then retract( attack ); end The integer values are taken from an enumeration. Altering the conditions in this way: numero_utenti >"25", numero_utenti < "80" makes no difference at analysis time. -- EDIT -- how to get this error (in the simplest case) 1. create a new package 2. create a new model 2.1 in the model, create a new fact (call it Fact1) 2.2 in Fact1, add just one integer field (call it value) 3. save changes and create a new rule WHEN Fact1( element : value > "10" && < "20" ) THEN [...] 4. save changes and try to analyse the package containing this rule Note: these steps are all made in guvnor
