Customer text input plugin bug

[littlesnack]

I need to write a custom field plugin.

The customer text input plugin (included with VM 2.0) would be a nice starting point, but when i click the add to cart button i get the following error (with firebug) and the cart isn't instantly updated.

Code Select Expand

Fatal error: Class 'VmTable' not found in ......\administrator\components\com_virtuemart\plugins\vmplugin.php on line 309
