>          Issue Type: Bug
>          Components: DSLs Editor
>    Affects Versions: 5.5.0.Final

>              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
