Is there any way I know wether the element object being built is the one which is going to be displayed? Then if it is not I could just skip the calls to webservices which cause delays and additional over head. Maybe looking at the $page variable passed in? > If the results of this webservice call are not expected to change too > often, you can implement some form of caching. Sadly they change depending on the input on the previous page - when a postcode is entered. This means I cannot really cache the values, although it might be an interesting idea to speed up accessing the remote Postcode webservice.
