Answer 1

Had a similar issue on an Enterprise build, so posting for anyone else that needs it - turned out I had to use the following in order to get it to work:

<remove name="enterprisecatalog.leftnav" />

Answer 2

im my case i have to get ride the block that whas type="catalog/layer_view" from local.xml and catalog.xml and put my modified type="catalog/layer_view" block . be sure there is only one block that contain type="catalog/layer_view".

Answer 3

I had <block type="catalog/layer_view" name="catalog.leftnav" after="currency" template="catalog/layer/view.phtml"/> twice. Deleted one line and fixed it.

Answer 4

For me Dubbo's answer was right, but more specifically I found out that Magento Enterprise touches the catalog_category_layered xml node in the enterprise_search.xml file

Answer 5

It is because catalog/layer_view module was called twice. You can search 'type="catalog/layer_view"' through your xml files. Remove the block you don't needed. Or change the type to another class

Answer 6

This causes the same problem. -adding the same attribute to the sort twice when building a collection:

...
    ->addAttributeToSort('color', 'asc')
    ->addAttributeToSort('color', 'asc');

NOTE: calling setCollection($this->getMyCollection); on the template caused my error, because 'color' was already added to the sort order as the default sort order.

SOLUTION:a quick way to fix this is to remove the default sort order from the request after obtain the value:

$this->getRequest()->setParam('order','');

otherwise extend the Block and override the setCollection() method for your particular needs.
