I tried to use your suggestions and found many other problems... :-(
I have an "add" view with 2 select boxes.
Changes in the 1st select are "observed" by an ajax->observeField that
fires a function in the controller and fills the option part of the
second select (e.g. 1st select lists countries and second select lists
regions of the selected country).
This works when the view loads the 1st time.
If there's a validation error the 1st select is ok but the 2nd one is
not updated. This is ok, when cake reloads the form the 2nd select
option list is empty.
So I tried to start the observedField function by changing the
selected option in the 1st select using javascript and the load event.
Javascript changes the select value But the observeField routine
doesn't start.
Moreover if I try to change manually (not in code) the select value
the observeField function starts only the second time I select a
value, not the 1st one.
This is the relevant code of my add.ctp view:
$options = array('url' => 'update_select','update' =>
'Model1Model3Id','type' => 'synchronous');
echo $ajax->observeField('Model1Model2Id',$options);
echo $javascript->codeBlock('function updateonReload()
{
var x=
document.getElementById("Model1Model2Id");
//alert(x.selectedIndex);
var tmp=x.selectedIndex;
//x.selectedIndex=0;
x.selectedIndex=tmp;
}');
echo $javascript->event('window','load','updateonReload()');
I'm a little bit lost...
Thank you
