This is probably an internal SWT error. Steps to reproduce: 1. Open printing dialog 2. Click on Change printer... 3. Click on Cancel Actual results: A dialog containing "Unhandled event loop exception No more handles" is opened and followed by a prompt to exit the workspace. Expected results: Showing of printing dialog without errors.
Please provide platform information. A stack trace would also be helpful.
Brian Fitzpatrick <bfitzpat> made a comment on jira SWITCHYARD-1822 Can't reproduce on Windows 7.
Tomas Rohovsky <trohovsk> made a comment on jira SWITCHYARD-1822 I have tested that on Fedora 19.
