Oleg Zhurakousky reassigned NIFI-3509: -------------------------------------- Assignee: Oleg Zhurakousky > Creating templates of copied and pasted PGs can cause issues > ------------------------------------------------------------- > > Key: NIFI-3509 > URL: https://issues.apache.org/jira/browse/NIFI-3509 > Project: Apache NiFi > Issue Type: Bug > Affects Versions: 1.1.1 > Reporter: Joseph Percivall > Assignee: Oleg Zhurakousky > Priority: Critical > Attachments: Screen Shot 2017-02-20 at 7.38.49 PM.png, Screen Shot > 2017-02-20 at 7.53.21 PM.png, Screen Shot 2017-02-20 at 7.53.34 PM.png > > > Using the following steps I was able to create a template which instantiates > with connections from one input port to another input port of another PG. See > the template here[1]. > See the first attached screenshot for the seed flow. After importing, it > originally gives an error "Cannot add Connection to Process Group because its > destination does not belong to this Process Group" and nothing appears to be > added but after I refresh the canvas parts of the original flow appear > (screenshot 2 and 3). > What is most odd, is that there are connections going from the input port > "input" of pg "test" to the input ports of other PGs. I didn't think that was > possible. > The steps I used to create it: > 1: create a PG "test" with input port "input", UpdateAttribute and output > port "output". Creating connections between them. > 2: Go to Parent group and copy "test". > 3: Go back into "test" and paste. > 4: Copy and paste "test" multiple times, creating the flow. > 5: Create a template of the flow > 6: When using the template, see the issue described. > The root cause of the issues, I believe, is that the id for the parent group > starts with "f3ac1eb5-1010-115a" and when I copied and pasted "test" into > itself it created the "test" pg with an id starting with the same value. > [1] https://gist.github.com/JPercivall/923519ef09500886c50a8f574f7662ca -- This message was sent by Atlassian JIRA (v6.3.15#6346)
