[jboss-jira] [JBoss JIRA] (DROOLS-1672) "not" in variable name doesn't work

[Edson Tirelli (JIRA)]

    [ https://issues.jboss.org/browse/DROOLS-1672?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13448108#comment-13448108 ] 

Edson Tirelli commented on DROOLS-1672:
---------------------------------------

I investigated this problem. It happens on the last reference to the variable name:

{code}.bob is not exactly 18{code}

The problem is that today the parser uses dynamic resolution to parse this variable name, and we can't allow keywords in name parts for dynamic resolution.

There is no easy fix for this until we get some kind of alternative for the dynamic resolution. I will postpone this ticket until either DMN 1.2 defines a context free grammar or we have an alternative for the dynamic resolution.

> {code}{ is not exactly 18 : != 18, bob is not exactly 18 : is not exactly 18(16) }.bob is not exactly 18"{code}
