The error happens and an number of places:
For example - When attempting to add a custom field you get.
Fatal error: Call to a member function getListFooter() on a non-object in /public_html/administrator/components/com_virtuemart/views/custom/tmpl/default.php on line 130
Or when adding or editing a Tax calculation you get.
Fatal error: Call to a member function getResultsCounter() on a non-object in /public_html/administrator/components/com_virtuemart/views/calc/tmpl/default.php on line 38
When adding or editing a product catagory you get
Warning: Invalid argument supplied for foreach() in /public_html/administrator/components/com_virtuemart/views/category/tmpl/default.php on line 75
# Category Name Description Products Published Ordering
Fatal error: Call to a member function getListFooter() on a non-object in /public_html/administrator/components/com_virtuemart/views/category/tmpl/default.php on line 140
Has anyone else run into these issues, and has anyone come up with a solution? Am I missing something

I am making decisions on a new project and need to know if I should go ahead in 1.5 or wait.
I am also a little confused that if its all imcompatable, how did Gavick create the products, tax codes etc

Any thoughts from Gavick and the community would be appreciated
Many thanks in advance.
