I have a js-function codeAddress() that processess the data from address and updates the values of fullAddress and validField.
The data of fullAddress and validField is passed by <p:ajax> to the backing bean, but the setter methods seem to get called one request delayed.
The alert() at the end of codeAddress shows the correct new data.
When address has onchange="test()" everything works fine an the backing beans setter methods are called as they should without any delay.
I am clueless what might be wrong here.

my jsf code:

<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:p="http://primefaces.org/ui">
<h:head>
        <script src="https://maps.googleapis.com/maps/api/js?v=3&amp;sensor=false"></script>
</h:head>

<h:body>
    <h:outputScript name="jsf.js" library="javax.faces" target="head"/>
    <h:outputScript library="js" name="bugMaps.js" />
    <body onload="initialize()" />
    <h:form id="addressForm">
        <p:inputText id="address" onchange="codeAddress()">
            <p:ajax process="fullAddress validField"/>
        </p:inputText>
        <p:message id="addressValidate" for=":addressForm:validField"/>
        <p:commandButton value="submit" />
        <p:inputText id="fullAddress" value="#{addressBean.fullAddress}" />
        <p:inputText id="validField" value="#{addressBean.valid}" />
    </h:form>

</h:body>
</html>

my JS:

var geocoder;
var map;
var valid = false;
var fullAddress = "none";

function initialize() {
    geocoder = new google.maps.Geocoder();
}

function test(){
    fullAddress = Math.random();
    document.getElementById('addressForm:fullAddress').value = fullAddress;
}

function codeAddress() {
    var address = (document.getElementById('addressForm:address').value + ", Germany");
    geocoder.geocode({'address' : address},function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            var latLong = results[0].geometry.location;
            var latitude = results[0].geometry.location.lat();
            var longitude = results[0].geometry.location.lng();
            var country, postal_code, locality, street_number, route;
            for (i = 0; i < results[0].address_components.length; ++i) {
                var component = results[0].address_components[i];
                if (!locality && component.types.indexOf("locality") > -1)
                    locality = component.long_name;
                else if (!postal_code && component.types.indexOf("postal_code") > -1)
                    postal_code = component.long_name;
                else if (!country && component.types.indexOf("country") > -1)
                    country = component.long_name;
                else if (!street_number && component.types.indexOf("street_number") > -1)
                    street_number = component.long_name;
                else if (!route && component.types.indexOf("route") > -1)
                    route = component.long_name;
            }
            if (typeof latLong != "undefined"
                && typeof latitude != "undefined"
                && typeof longitude != "undefined"
                && typeof route != "undefined"
                && typeof street_number != "undefined"
                && typeof postal_code != "undefined"
                && typeof locality != "undefined"
                && typeof country != "undefined"){
                valid = true;
                fullAddress = results[0].formatted_address;
            }
            else{
                valid=false;
                fullAddress="none";
            };
        }
        else{

            valid=false;
            fullAddress="none";
        }
        document.getElementById('addressForm:fullAddress').value = fullAddress;
        document.getElementById('addressForm:validField').value = valid;
        alert(fullAddress + valid);
    });
};

    This is not a duplicate question.
    The first fault was using <p:ajax> to submit data that was to be altered by JS, because the ajax request is already prepared while the script is still running.
    The second mistake was to use the non-cross-browser-compatible jsf.ajax.request.
    Now I simply deleted the <p:ajax> and use a solution with jQuery. This function is simply called from the geocoders callback function:

    function jsfSubmit(){
    document.getElementById('addressForm:fullAddress').value = fullAddress;
    document.getElementById('addressForm:validField').value = valid;
    $.ajax({type:'POST', data:$('#addressForm').serialize(), success: function(response) {
        if(valid){
            var destPage = 'nextPage.xhtml';
            window.location = destPage;
        }
    }});
};
