Filter expression of async table

Hi there,

I would like to know how to write a filter expressions for async tables. I checked the documentation of webmethods 8.2 but I could not find anything useful.

I have got a FilterableSelectableListTableContentProvider, and it is bound to an async table. I found a “Filter” option under the Expert tab. Unfortunately I do not know how to use it. There is no any information about Filter expression on the web.

Thank you in advance.

Kind regards,
Adam
