[jboss-jira] [JBoss JIRA] (DROOLS-2988) Question Mark should always be leading in qualified names

Question Mark should always be leading in qualified names --------------------------------------------------------- Key: DROOLS-2988 URL: https://issues.jboss.org/browse/DROOLS-2988 Project: Drools Issue Type: Enhancement Reporter: Edoardo Vacchi Assignee: Matteo Mortari Priority: Major Labels: drools-core The QuestionMark identifier is recognized as part of a qualified name, but it should only be admitted as the first fragment. Currently we are not accounting for edge cases such as `foo.?.bar`. This should be probably reported as a syntax error, as it does not make any sense, but we can ignore it for now. Relevant lines: https://github.com/kiegroup/drools/blob/c82693e41ce4713ca466fb6947e4a046e... Memo: Recognition of `? ` is done via a global variable. We should rather refactor this as to carry the information correctly in a DirectCompilerResult. This was deemed a bit complicated because of the level of nesting of tree nodes. We can do this when/if we refactor the compiler to use a proper AST
