Our Jazz application defines several work item types. The inline editor (which I have read defines what is displayed for rich hover) for all types except one is configured as the default inline editor. However, one work item type uses an inline editor which is a reference to a section of that work item type's "work item editor" (there is a section called "details" in the work item editor. So the inline editor is set to be <work item editor>.details. This used to function correctly in RTC's 3, 4 and 5. However, we recently upgraded our application to RTC 6.0.3 and now it appears that the default inline editor is being used for this work item type as well. So it appears that in 6.0.3, this setting is being ignored.

BTW, I did try changing the inline editor to the default, saving the config and then changing it back to the custom setting. This did not have any effect.
