[jboss-jira] [JBoss JIRA] (DROOLS-1249) DSL rule doesn't compile when DSL contains more general pattern defined before more specific pattern.

[Edson Tirelli (JIRA)]

     [ https://issues.jboss.org/browse/DROOLS-1249?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Edson Tirelli closed DROOLS-1249.
---------------------------------
    Resolution: Rejected


Tibor, this is working as intended.

DSL mappings are applied in the order they are defined, so it is mandatory to place more specific mappings in the grammar before more general ones. The documentation contains the following node:

"The order of the entries in the DSL is important if separate DSL expressions are intended to match the same line, one after the other."

>    Affects Versions: 6.4.0.Final

>            Priority: Minor

> When using DSL where more general pattern is defined sooner than more complex pattern, e.g. this: 
> [when]There is a number with=i:Integer()
> [when]There is a number with value of {value}=i:Integer(intValue() == {value})
> DSL rule fails to compile with error like this: 
> [ERR 102] Line 4:20 mismatched input 'of' in rule "sample rule"
> Used DSL rule: 
> package org.test
> rule 'sample rule'
> when There is a number with value of 10
> then end
> I will make a PR with reproducer for this.
