Hi,

Is there a way to perform a reverse sort in an OCL query? Looking on the web the only place I found a reference to reverse OCL sorting indicated that putting a "-" in front of the sort field would work e.g. sortedBy(e|-e.name). But I get an exception:

Caused by: org.eclipse.ocl.SemanticException: Cannot find operation (-()) for the type (String)

I also tried sortedBy(-e|e.name) but got this error instead:

Caused by: org.eclipse.ocl.SyntaxException: 2:374:2:374 "::" expected instead of "|"

Is that the correct syntax? Is there another way to reverse sort?

Thanks,
Warwick
