             Summary: Paragraph contents and output are overwritten by cloned notes when in personal mode
                 Key: ZEPPELIN-3896
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-3896
             Project: Zeppelin
          Issue Type: Bug
    Affects Versions: 0.7.1
         Environment: This is independent of the interpreter.
            Reporter: Roeland van der Veen


When cloned notes are used in personal mode, the contents of the paragraph (both editor and output) that is run are sent to the corresponding paragraph of the originally cloned note, overwriting any existing content in that paragraph.

Steps to reproduce:
 # Create new note ("A")
 # Clone this note ("B")
 # Open the two notes side-by-side for comparison
 # Put note A in Personal Mode
 # Edit the first paragraph in note A and run paragraph (some print command for example)
 # Both the contents of the editor, and the output in B is changed to the values of A, overwriting any existing values.

This bug occurs:
 * When note A is put in personal mode, affecting B
 * When note B is put in personal mode, affecting A
 * Both ways when A and B are put in personal mode
 * Between more than two notebooks when more clones are made
 * In anonymous mode
 * With different users executing the affected notes

Part of the cause seems to be duplicated paragraph IDs.
