Rascal edit method documentation not correct

http://tutor.rascal-mpl.org/Rascal/Libraries/util/Editors/edit/edit.html

Calling edit(|http://www.google.nl|); or edit with any other LOC that I tried, results in the error message

"|plugin://rascal_eclipse/src/org/rascalmpl/eclipse/library/util/Editors.rsc|(1289,4,<41,5>,<41,9>): ? >not supported on loc and loc
Advice: |http://tutor.rascal->mpl.org/Errors/Static/UnsupportedOperation/UnsupportedOperation.html|"

While it's stated in the documentation that edit(loc) should work.

Also, should the edit function be able to open an existing sourcefile, or is it only to open new empty files?

Thanks

This line in the standard library of the version of Rascal you use contains a bug indeed. Nick Lodewijks found a workaround: copy the edit function from the standard library and remove the use of the ? operator. That should give a working function for your context. In the mean time the bug was solved on the master. Thanks for reporting!
