[jboss-jira] [JBoss JIRA] Updated: (JBRULES-1272) DSL : String index out of range: -1

[Mark Proctor (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBRULES-1272?page=all ]

Mark Proctor updated JBRULES-1272:
----------------------------------

    Fix Version/s: 4.0.3
                   4.1.0
                   FUTURE

This fix needs to be back ported to be part of 4.0.3

>From kris:
"This does not seem to be related to the editor itself, it is the DSL
compiler which seems to be throwing an exception if you have a DSL
sentence where 2 params are only 1 character apart (doens't matter
whether it is a space or not), like "My DSL sentence with
{key1}_{key2}".  If the distance is at least 2 characters, then there
is no problem.  The problem still exists in trunk as well.

Looking at the svn history, it is probably related to the fix edson
this in DefaultDSLMappingEntry for JBRULES-1164 (commit 15069): Fixing
DSL files with embedded () on key."
