[betwixt] - Handling java.awt.Point, Dimension and KeyStroke
I have a bean with properties whose types are non bean compliant Java classes -- java.awt.Point, java.awt.Dimension and java.awt.KeyStroke. The xml is written correctly, but after parsing, the resulting instances don't have the right values since Point, Dimension and KeyStroke are not beans.
Has anyone already solved this problem?
Thanks,
Pam
Ex:
<?xml version="1.0" encoding="UTF-8"?>
<Point>
<x>10.0</x>
<y>15.0</y>
</Point>
BeanReader reader = new BeanReader();
reader.registerBeanClass("Point", java.awt.Point.class);
Point p = (Point)reader.parse...
The resulting point is not [10,15] since there is no setX() and setY() on java.awt.Point.

now that i know jelly a little better i think that i can see how some
of the newer beanutils ideas would probably benefit jelly but these
changes are many about factoring the code better so that it's easier to
customize (rather than moving more things into beanutils). some of
these should allow jelly tag libraries to be implemented more elegantly
and easily than at present. i'll probably have more motivation to work
on them if they are going to be useful in jelly.
stephen's been quietly been working on a separate convert component.
the idea is that this component will have a completely new design
unconstrained by backward compatibility. hopefully, you should be able
to plug in an adapter when the appropriate functionality has been
factored out of beanutils. maybe we should catch up on the progress
he's been making...

We had a similar problem with Jelly and I remember we have crafted the
notion of "converters" to convert strings to Point, DebugGraphics,
Dimension, and Color. None yet for KeyStroke but that could be easily
solved, I remember it became hard when we wanted Font...
I think the issue was that these converters should be living at the
level of BeanUtils, having a notion of "converter-context". Robert,
didn't you mention that there was something changing in this area on
the BeanUtils side after your jaxme efforts ?
thanks

hi pamela
betwixt is bean-centric. it's support for other types is pretty basic
at the moment (i'm afraid). i don't know of any way to do this in
betwixt at the moment.
but this is a pretty common use case so there's a chance that something
like this could get implemented sooner rather than later. i'll have a
think about the design.
