[jboss-jira] [JBoss JIRA] (DROOLS-1558) DMN case where list of single element shall be considered a singleton value

[Matteo Mortari (JIRA)]

     [ https://issues.jboss.org/browse/DROOLS-1558?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Matteo Mortari updated DROOLS-1558:
-----------------------------------
    Description: 
In the attached model decision "Positions of Los Angeles teams" is wrong:

{code:java}
index of(NBA Pacific[city="Los Angeles"])
{code}

As the "index of" function expects 2 parameters.

It could be rewritten as:

{code:java}
index of(NBA Pacific.city, "Los Angeles")
{code}

which would work, but there is an expectations it should also work with:

{code:java}
index of( NBA Pacific, NBA Pacific[city="Los Angeles"])
{code}

under the assumption there is only 1 team located in LA.

  was:
The attached model is not completely working. This is likely to the fact that the filter selection operator is not working. E.g.:

{code}
max( NBA Pacific.wins )
{code}

Should return the team with the most wins in the {{NBA Pacific}} list of teams.
