Hi Andreas,
i believe you have an error in your js code. The preHook/postHook
arguments have to be functions just like the callback argument.
Otherwise your functions 'showLoadText' and 'hideLoadText' are evaluated
beforehand and the result set to preHook/postHook (which i assume is
undefined).
The code should look more like this:
AjaxMethods.findByCountryId(countryId, {
callback:function(data) { afterAjax(data); },
preHook:function(obj, loadText) { showLoadText(obj, loadText); }
});
}
