Re: intake and business object mapping: confusing StringKey with String in setProperies

[John McNally <jm...@collab.net>]

This is a problem with java's bean introspection classes.  It is
difficult to fix as there are bugs in different classes in different jdk
versions.  The version in cvs will work for jdk1.3.x, I believe.  You
can remove the String convenience method from torque's Object.vm
template and regenerate your sources for an easier fix.
