This code is the composite of the work of lots of people and they also built on those
before them. References to them is at the bottom, but I wanted to acknowledge this at
the start.
+The key to the below is that the image tag will send
button.submit.x=19&button.submit.y=10 and the properties button.submit.x and
button.submit.y will be set as follows:
+
+{{{
+ [ActionForm].getButton().getSubmit().setX(new Integer("9"));
+ [ActionForm].getButton().getSubmit().setX(new Integer("8"));
+}}}
+
Here's the button I use.
