[jboss-jira] [JBoss JIRA] (JBRULES-2819) DSL parsing/expansion: '\', '$', empty value, empty condition

DSL parsing/expansion: '\', '$', empty value, empty condition --------------------------------------------------------------- Key: JBRULES-2819 URL: https://issues.jboss.org/browse/JBRULES-2819 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-compiler-DSL Affects Versions: 5.1.1.FINAL Reporter: Wolfgang Laun Assignee: Edson Tirelli Fix For: 5.5.0.CR1 DSL parser does not accept an empty "value" section, e.g. [when] a man loves a woman= Expansion of a rule with an empty condition results in "whenthen". The DSL parser escapes '$', but not '\' in value sections. It should not modify the value section except for "normalizing" variable references. Variable references should be restricted to a "clean" character sequence (e.g. Java identifier). The current expansion using replaceAll is too fragile. I have emailed three reworked source files AntlrDSLMappingEntry.java DefaultExpander.java DSLTokenizedMappingFile.java to Edson, but I didn't change the parser itself.
