I use PropertySelection component. In some cases my web application
require to make SELECT(list box) disabled using javascript. When it is
disabled and I submit data from form to server an error occurs.
I investigated Tapestry error page and found that browser has not sent
parameter for disabled SELECT element.
Tapestry error message is: null
