DSL rule doesn't compile when DSL contains more general pattern defined before more specific pattern. ----------------------------------------------------------------------------------------------------- Key: DROOLS-1249 URL: https://issues.jboss.org/browse/DROOLS-1249 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 6.4.0.Final Reporter: Tibor Zimányi Assignee: Mario Fusco Priority: Minor When using DSL where more general pattern is defined sooner than more complex pattern, e.g. this: [when]There is a number with=i:Integer() [when]There is a number with value of {value}=i:Integer(intValue() == {value}) DSL rule fails to compile with error like this: [ERR 102] Line 4:20 mismatched input 'of' in rule "sample rule" Used DSL rule: package org.test rule 'sample rule' when There is a number with value of 10 then end I will make a PR with reproducer for this.
