The "anymore" is the key question. I don't know whether it worked before or

Yes, without some sort of regression testing mechanism, it is possible.

... compare what is going on in AddLMVisitor to the addLayoutManager()
method that was in revision 1.3 of fo/flow/

It is not really mine -- I just placed it where it is.

It is an anonymous inner class that I think is overriding the constructor.

I don't know. I recommend going back to a version of the code before the
AddLMVisitor was checked in, and seeing 1) whether it worked properly then,
and 2) what it was doing, and comparing that to what is happening now. The
AddLMVisitor was checked in on Aug 19, 2003 at 0:53:53 (I think that is
GMT). As I think about it, if the setupBasicLinkArea() method was used at
all, I probably should have gotten a compile error when I moved it to
AddLMVisitor. I'll bet that code wasn't being used at all. I'll be glad to
investigate it when I get done with the pioneer LS work (possibly in the
next few days). If it is slowing you down, or if we are pretty sure it
worked before this change, I'll work on it right away.
