Problem in recurring event with custom form

Hi Everyone,

I have problem with recurring event extension. I have used recurring event extension and map ext. when i add new event it added successfully but when i refresh event page or visit that page any time after adding event it update my event and set end_date as 0000.00.00 and event_length as 2851200,

when i refresh page it calls two urls:
1: codebase/php/events_rec.php?timeshift=-330&uid=1329206331770
2: codebase/php/events_rec.php?editing=true

function init() {

	scheduler.config.xml_date="%Y-%m-%d %H:%i";
	scheduler.config.prevent_cache = true;		
	scheduler.config.details_on_create=true;
	scheduler.config.details_on_dblclick=true;		
	scheduler.locale.labels.map_tab = "Map";		
	var dp = new dataProcessor("codebase/php/events_rec.php?a=1");		
	dp.init(scheduler);		
	scheduler.init('scheduler_here','',"month");
	scheduler.load("codebase/php/events_rec.php");		
	scheduler.locale.labels.section_customer_id="Customer";
	var sections=[
	<?php 
	$i=1;
	$j= count($customers);
	foreach($customers as $customer)
	{
	?>
		{key:<?=$customer['id']?>, label:"<?=$customer['customer_name']?>"}<?php echo($i<$j?',':'')?>
	<?php 
	$i++;
	}
	?>
	];
	
	scheduler.config.lightbox.sections=[
		{ name:"description", height:50, map_to:"text", type:"textarea", focus:true },			
		{ name:"customer_id", height:23, type:"select", options:sections, map_to:"customer_id"},
		{ name:"recurring", height:115, type:"recurring", map_to:"rec_type", button:"recurring"},
		{ name:"time", height:72, type:"time", map_to:"auto"}	
	];

}

I have customize light box form field.

Thanks!
