Hi forum,

I installed the latest ecommerce module (together with the ecommerce_product_variation, payment modules and the featured products widget). My current versions are

ecommerce: r1284
ecommerce_product_variation : r1409
payment: build date 21 July 2011 ( )

I had an earlier version of the ecommerce module installed on my development site before and it worked well (before the product variations became a separate module). Now I always have a problem with the checkout page:

[User Error] While the order can be edited, you must call the runUpdate method everytime you get the details for this modifier

I just can't find the problem. When I add a product to the cart it is nicely displayed in the cart sidebar, but I did notice that the "Cart" page is empty (no products appear).

The only modifier I have enabled at the moment is the SimpleShippingModifier, but removing that doesn't change anything. I also tried to completely remove all ecommerce related pages from the CMS and I removed all ecommerce, payment, etc. database tables for a "fresh" install but to no avail.

Anyway, if anyone has any hint I would be very grateful. Here is the complete trace:

Line 241 in /path/to/ecommerce/code/model/OrderModifier.php


232 // ######################################## *** template functions (e.g. ShowInTable, TableTitle, etc...)
234 /**
235 * tells you whether the modifier shows up on the checkout / cart form.
236 * this is also the place where we check if the modifier has been updated.
237 *@return Boolean
238 **/
239 public function ShowInTable() {
240 if(!$this->baseInitCalled && $this->canBeUpdated()) {
241 user_error("While the order can be edited, you must call the runUpdate method everytime you get the details for this modifier", E_USER_ERROR);
242 }
243 return false;
244 }
246 /**
247 * some modifiers can be hidden after an ajax update (e.g. if someone enters a discount coupon and it does not exist).

Just to add that, I tested to remove the red line above from /ecommerce/code/model/OrderModifier.php and all looks OK, but I'm wondering if this will not create any other problems... I just don't really know what this line does or what runUpdate() really does.

Hi Anatol,

I'm assuming you're making use of trunk code, and I'm also going to recommend using the branches/0.8 branch...or 0.8.x tags.

That runUpdate function was introduced when changing the way the modifiers are introduced for an order. I believe the function should be run every time the order total needs to be re-caclulated.

The modifiers system needs some serious review to be honest, and I have plans to do so.
