I'm trying to implement an NSOutlineView in a Java application; at the
moment, the app fails on the first mouse click onto the NSOutlineView
object. The failure is usually a SIGBUS; when I ran it under gdb to get
the stack trace below, the signal was "EXC_BAD_ACCESS".
I'm mailing the list because I thought I remembered seeing a post on the
the Project Builder list that there are known problems with Java and
NSOutlineView (or perhaps the Java bridge). Is this correct? Is there
a known workaround? Or am I doing something wrong or incomplete?
If this is a known problem, are there release notes I should have known
about?
Thanks in advance...
