Rule silently discarded if RHS calls an undefined DRL function -------------------------------------------------------------- Key: JBRULES-2222 URL: https://jira.jboss.org/jira/browse/JBRULES-2222 Project: JBoss Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-compiler Affects Versions: 5.0.1.FINAL Reporter: Wolfgang Laun Assignee: Mark Proctor If a function bar is called on a RHS of a rule in the same .drl file without being defined in the same .drl file, the .drl is compiled without kBuilder.getErrors() returning an error, and the rule is silently discarded (not firing, although it should). - Note that this error occurred when there was a function bar defined in another .drl file of the same package.

[JBoss JIRA] Created: (JBRULES-2761) Restriction operator parameters should be strings, not token sequences

by Wolfgang Laun (JIRA)

Restriction operator parameters should be strings, not token sequences ---------------------------------------------------------------------- Key: JBRULES-2761 URL: https://jira.jboss.org/browse/JBRULES-2761 Project: Drools Issue Type: Feature Request Security Level: Public (Everyone can see) Reporter: Wolfgang Laun Assignee: Mark Proctor User defined operators (similar to "matches" or the temporal ops) may have parameters, written in '[' and ']' after the identifier denoting the relational operator. Text between the brackets is currently parsed as a "chunk", requiring the text to be composed from tokens recognized by the lexer. This is too restrictive since all Unicode characters that aren't letters (and this part of an identifier) are simply dropped. It should be simple to parse the text between '[' and ']' as a special form of recursive string, with brackets as delimiters. This means that op[foo[1]] is OK, but op{bar[[] is not. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
