In the TextImage component, the Style tab has lost the css selection dropdown that used to show up when editing the component. It now just shows a blank area. It should have a dropdown for image alignment (left or right are your choices). This doesn't appear anymore.
This tab is xtype componentstyles (String), so I don't know where it references the source for the dropdown values. My local instance of CQ5 works just fine.
I cannot just add an xtype selection and feed it values because the css that gets added to the JSP code is outside the component's .jsp-specific page
The problem is that a design path variable went missing. We don't know why or how, but the solution is as follows.
Open up Content Repository
Go to /content/-sitefolder-/ and expand
Click on jcr:content and view properties
Check for attribute cq:designPath and its value /etc/designs/-sitefolder-; add to properties if it doesn't exist
