[jboss-jira] [JBoss JIRA] (DROOLS-3271) [DMN Designer] Double-clicking connectors in DRD throws exceptions

[Michael Anstis (Jira)]

    [ https://issues.jboss.org/browse/DROOLS-3271?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13658678#comment-13658678 ] 

Michael Anstis commented on DROOLS-3271:
----------------------------------------

[~tirelli] The _error_ is deliberate (or at least let's say it's a _managed_ violation of rules defining the construction of DMN files with Stunner).

The rule that has been violated checks that the DMN graph is does not contain circular references.

I'd have to guess that your "_accidental_ double click" tried in essence to attach the connector to itself leading to the circular reference (or something like that). The reporting mechanism is core-Stunner. However, as a low priority, we could investigate why you received the message (I could not replicate by "_deliberately_ double clicking" connectors).
