Payment Popup not activated

-- url of the page with the problem -- : analoghifi.no/
-- HikaShop version -- : 2.6.0
-- Joomla version -- : Joomla! 3.4.4 Stable [ Ember ] 8-September-2015 21:30 GMT
-- PHP version -- : 5.4.16
-- Browser(s) name and version -- : Chrome Versjon 46.0.2490.80 m
-- Error-message(debug-mod must be tuned on) -- : None

I have a custom eventhandler (custom.js, line 2) attached by jQuery(window).on('load',...) (same result using jQuery(document).ready) which loads and handles dynamic loaded Delivery-alternativs from external provider
The code runs on the hika/checkout page only

When the 'Finish'-button is pressed and document reloads I have a short test detecting that 'Finish' has been pressed and returns from my handler without doing anything (beside the test)

This handler prevents the next step (payment popup) from beeing loaded despite the fact that the url changes from analoghifi.no/index.php/hika/checkout to analoghifi.no/index.php/hika/checkout/task-step/step-1 . The page itself stays the same but if I press 'Finish' one more time the page changes to the step 1 page and the payment popup is presented
If I replace my test by a simple return the 'Finish' button works as expected (!)

It seems to me that there is something wrong with the eventhandler(s) responsible for loading the popup-window

The site is closed for public access so I will have to create a user/pass for you if you will look at the problem (please send me a private mail if so)

Contact form posted

I have done some modifications to some of the templates for checkout, eg.: www.hikashop.com/forum/checkout/880061-r...template.html#218379

The cart-template has also been modified in order to calculate and display total cart weight

No the problem is still there, ref.attached images

When pressing Fortsett on hika-1: the url changes from checkout to checkout/task-step/step-1 but the page stays the same and no popup is presented (re. hika-2)
When pressing Fortsett on hika-2: the url stays the same, the page changes to the step-1 and popup is presented (re. hika-3)

Checkout settings images attached

More information

div.hikashop_shipping_group is emptied before custom delivery options are placed there and is present when Fortsett is pressed the first time. The div is empty when Fortsett is pressed the second time so I have tested to empty the div.hikashop_shipping_group before submit but that did not help

I have also changed the options name to 'hikashop_shipping' and emulated attribute checked='checked' but that did not help either

Native hikashop_shipping radios has values like manual_9 and id hikashop_shipping_manual_9 which I guess is used to lookup some values in the database(?)

How will your server-side submit handler react to my value like SERVICEPAKKE and id hikashop_shipping_SERVICEPAKKE?

ps! The username / password I sent in the contact form has admin-rights so feel free to take a look in the backend if you need to

I have changed the hardcoded onclick eventhandler on address radios and checkbox for use same address because they submitted the form. I guess the submit is there to ensure that shipping methods limited geographically becomes updated but there seems to be I bug in the serverside code because it redirects to /checkout/task-step/step-1 which is the same as the url for Finish

I have also added native shipping methods that matches the custom methods and changed the code to create values and id like the native shipping methods but it still fails to open the payment popup

It would be nice if an error message is created if/when a validation fails or some other error occures

EDIT: I just discovered a notice message in a confirmation mail:

Notice: Use of undefined constant JPATH_COMPONENT - assumed 'JPATH_COMPONENT' in /var/www/vhosts/analoghifi.no/httpdocs/libraries/legacy/view/legacy.php on line 164

I have downloaded and reinstalled the latest version

This is in my page after a failed Finish:

<div id="system-message-container">
	</div>

Regarding 3: defined('JPATH_COMPONENT') or define('JPATH_COMPONENT', '');

I have tried deactivating the option "auto submit shipping and payment methods selection" in the HikaShop configuration but that does not solve the problem

I understand your way of keeping totals and shipping-methods updated on screen by submitting all changes to address or shipping method to the server and that the server-side submit-handler requires that all shipping methods and their prices exists in the database.

Support for dynamic price has been added to template checkout/shipping.php (line 4-8 in code below):

if($this->config->get('auto_submit_methods',1) && empty($checked))
				$checked.=' onclick="this.form.action=this.form.action+\'#hikashop_shipping_methods\';this.form.submit(); return false;"';

			if (isset($_REQUEST['shipping_price'])) {
				$rate->shipping_price = $_REQUEST['shipping_price'];
				$rate->shipping_price_with_tax = floatval($_REQUEST['shipping_price']) * (1 + $rate->taxes[0]->tax_rate);
				$rate->taxes[0]->tax_amount = $rate->shipping_price_with_tax - $rate->shipping_price;
			}
				
			if(empty($rate->shipping_price_with_tax))
				$rate->shipping_price_with_tax = $rate->shipping_price;

1. onload-handler loads the external shipping methods by ajax using postalcode and weight picked up from screen
2. ajax onload-handler displays the shipping methods and triggers click on default shipping method which add or set a hidden input (shipping_price)
3. All screen objects that are changing shipping_address or shipping_price calls a function that recalculates and displays new totals

Added 1 if in checkout.php, line 1022, terminated on 1032:

if (!isset($_REQUEST['shipping_price'])) {

$app->setUserState(HIKASHOP_COMPONENT.'.shipping_method', $shippings);
$app->setUserState(HIKASHOP_COMPONENT.'.shipping_id', $shipping_ids);
$app->setUserState(HIKASHOP_COMPONENT.'.shipping_data', $shipping_datas);
