Manufacturer Product list Pagination Not Work After Upgrade to 2.0.22a

[copierx]

Hello,

1- When click on show all manufacturer products i can only view the first page of products, click on other page listing return me to first page,
I have check both with sef and orginal links no changes. still i can not browse over pagination.

2- Sometimes only shows a few products from manufacturer or it is completely empty.

When i have check source code of page ; link is one of the category page from shop.

"index.php?option=com_virtuemart&view=category&virtuemart_category_id=159" rel="canonical"

Vm debug for empty manufacturer products page:
------------------------------------------------------------------------------------------------------------------

The interesting thing is no problem when trying to browse over categories pages. Shows full products and no pagination problem.

Joomla! 2.5.13
VM: 2.0.22a
Php: 5.3.26 / i have also test on 5.4
Mysql: 5.5.32-cll / i have also test on 5.3

I have a very similar problem - did you figure out a solution?

Categories all work fine, but pagination for manufacturers doesnt work so well. When we click on page 2 to view the 2nd page of manufacturer products, the page just seems to refresh?

Maxim, copierx wrote very detailed and I assume sandstorm has the same version ;-) Thanks for doing your job, happens.

I just tried to reproduce the error. Works for me. But as you can see we had to work on this. Maybe the 2.0.24c fixes it already for you. 2.0.25 is on the way.

Thanks Maxim, very helpful. 
I was merely responding to copierx, to see if he/she had found a solution themselves, as my post suggested.

I have already discussed further here with full details of Joomla, PHP version, VM versions tried, etc http://forum.virtuemart.net/index.php?topic=120197.msg411238#msg411238

The problem is /public_html/administrator/components/com_virtuemart/models/product.php
  if ($lastCatId != $manid ) {// Condition is only True
       $limitStart = 0;
       } else
       {          $limitStartString = 'com_virtuemart.' . $view . 'm' . $manid . '.limitstart';
                   $limitStart = $app->getUserStateFromRequest($limitStartString, 'limitstart', JRequest::getInt('limitstart', 0), 'int');
                }
