I have just upgraded from v 1.8.1 to 1.8.2 and am receiving an error when clicking on a SKU # in any ecommerce report.
Anything that can be done to help me resolve this would be extremely appreciated.

Thanks Matt,
The patch was semi successful, I had to make a quick similar edit @ line 519.

There is no longer an error, but no graph data is available. I have attached two screenshots. One to demonstrate the lack of data for the graph, and the other one showing the dashboard widget with accurate data for the same sku.

Thank you VERY much for looking at this. It is really appreciated.



public function getFilteredTableFromLabel($label)
	{
		$newTable = $this->getEmptyClone();
		$row = $this->getRowFromLabel($label); 
-                if ($row !== false)   
+		if ($row !== false && isset($this->rows[$row]))
		{
			$newTable->addRow($row);
		}
		return $newTable;
	}

do you have the problem on each day or only on some days?
I would like to be able to reproduce the problem to be able to fix it properly… any tip on how to reproduce would be great?
