Description Jacques Bouthillier

When setting an existing group in the R4E preference on a SOLARIS workstation, I got the following error:
java.lang.NullPointerException

Another occurence for a null pointer:

I looks like the selection for the group file is wrong, I may have selected a file which did not have the    " _root.xrer" , so it generated the preceding null pointer
