[Guilherme Gomes (Jira)]

    [ https://issues.jboss.org/browse/DROOLS-3892?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13730025#comment-13730025 ] 

Guilherme Gomes commented on DROOLS-3892:
-----------------------------------------

[~jomarko] Personally, I see this row as something to _help_ users. But, if they want to remove the added row, they should be allowed to do that. There's nothing in the DMN spec saying that a Structure ~Item Definition~ Data Type _must_ have one field at least.
