Guided Rule Editor does not support Magic Characters in DSLs ------------------------------------------------------------ Key: DROOLS-2043 URL: https://issues.jboss.org/browse/DROOLS-2043 Project: Drools Issue Type: Bug Components: DSLs Editor Affects Versions: 5.5.0.Final Reporter: Hendrik Wouters Labels: dsl, guided_editor, guvnor, magic_characters, regex Validation of a DSL rule in the guided editor fails when the DSL contains regex magic characters, such as '?'. Example DSL: [when]Assignment "{$assignment}" is {numberOfDays} days? overdue = {$assignment}: Assignment( hasDeadline before daysAgo({numberOfDays}) ) In the textual rule editor, this works fine: - Assignment "$a" is 1 day overdue - Assignment "$b" is 2 days overdue In the guided rule editor, it doesnt. Magic characters appear to be ignored, and no match with the DSL is made. Verification gives the following errors: [Assignment Overdue (Guided DSL)] [ERR 102] Line 5:13 mismatched input '"$assignment"' in rule "Assignment Overdue (Guided DSL)" [Assignment Overdue (Guided DSL)] Parser returned a null Package
