This action is invoked to update the values of a single-valued compound
property. It retrives its parameters from
UpdatePropertyForm and
processes the values received for each simpleName parameter.
If they are correct, updates the property and redirects to
UpdateCompoundProperty action, else returns to the input frm.
Of course, the properties to update are only those simple and single valued
because these are the ones the user can give values using text-boxes.
Properties that are not of this kind are not updated because the user can
give values to them in the JSP frm.
