Filter parameter sent by fnFilter is empty (server side processing)

cequadrat

Hi everybody,

just a short question: I'm using server side processing and would like to use an external search field for a global search.

The global search is initiated through a key up event on a text field which then calls the fnFilter function of the datatable. But on the server I can only see an empty string. If I use the internal global search field it is working. Is there any additional setting which is neccessary?

Cheers,
Chris
