Hi OME team,
I just ran into a weird permission-related bug in OMERO.iviewer. When a user who has a different default group tries to select a Well’s worth of images and wants to Open With it with iviewer, he/she gets “No image data” in the right-hand panel. When changing the default group to the group that “owns” that data, there’s no problem, and viewing the individual images in the Well also is no problem, so the issue appears to be limited to selecting at the Well-level. And in case it makes a difference, this is a Read-Annotate group.
This gives somewhat bizarre and unexplainable behavior to a user so hopefully it can be resolved easily in a near-future version of iviewer.
