[Xswt-developer] Tree-based XSWT and XSWTExceptions

[<ha...@id...>]

Hi,=20

There's one snag with the new tree-based design of XSWT: It's more =
difficult
to give precise error messages, since information about line and column =
is
lost. When implementing the new design, I replaced the line and column =
in
many calls to new XSWTException with -1 and -1. I haven't had time to go
through them, but I guess the best solution is to redefine XSWTException =
to
hold an element instead of line, column and then pass the element to the
constructor instead. Hopefully the element's toString() method is
informative, which at least the default element implementation's is. In =
some
cases the line and column is passed into methods that use them for =
throwing
nice XSWTExceptions, and in these cases, the element should be passed
instead.

Have a nice summer!
