Comment (by Dieter_be):
I can confirm this.
here is the code to get a working observer that submits when the contents
of any of fields of the form have changed (with frequency 1s)
{{{
<?php echo $ajax->observeForm("InvoicelineAddForm" .
$invoiceline['id'],array('url'=> array ('action' =>
'edit_ajax','controller' => 'invoicelines'),
'frequency' => '1',
'indicator' => 'hourglass' . $invoiceline['id'])); ?>
//<![CDATA[
new Form.EventObserver('InvoicelineAddForm1', function(element, value)
{new Ajax.Request('/colomanager/invoicelines/edit_ajax',
{asynchronous:true, evalScripts:true, onComplete:function(request, json)
{Element.hide('hourglass1');}, onLoading:function(request)
{Element.show('hourglass1');},
parameters:Form.serialize('InvoicelineAddForm1')})})
//]]>
}}}
With the following code, the frequency is ignored. when you change a
field, nothing happens until you actively de-focus the field (eg click
somewhere else on the page). Only then the ajax request happens.
{{{
<?php echo $ajax->observeForm("InvoicelineAddForm" .
$invoiceline['id'],array('url'=> array ('action' =>
'edit_ajax','controller' => 'invoicelines'),
'frequency' => '0.2',
'indicator' => 'hourglass' . $invoiceline['id'])); ?>
//<![CDATA[
new Form.EventObserver('InvoicelineAddForm1', function(element, value)
{new Ajax.Request('/crm-new/invoicelines/edit_ajax', {asynchronous:true,
evalScripts:true, onComplete:function(request, json)
{Element.hide('hourglass1');}, onLoading:function(request)
{Element.show('hourglass1');},
parameters:Form.serialize('InvoicelineAddForm1')})})
//]]>
}}}
