Bug: ROI comment editing failing after initial save

[will-moore]

As reported by @pwalczysko

The ROI editing comment works only when you close and reopen the iviewer

Workflow 1 (does not work)

• Open iviewer
• Create.roi
• add comment
• save roi
• try to edit the comment -> fail

Workflow 2 (does work)

• open iviewer
• create roi
• add comment
• save
• close iviewer
• reopen the same image in a new tab in iviewer
• select the roi you commented on in previous steps above

• edit the roi -> works as expected

  There is no difference in behaviour between 0130 and 0140 iviewer versions The above 2 workflows apply for both
