Hi list.

I'm getting AV when using

if (Field.FieldName = 'XX') then begin ...

in OnDataChange because Field = nil.
Is there any way to know which particular field that is changed and triggering the event?
When field XX is changed I wan't to update SQLWhere to filter a "lookup"-Query that is connected with keysource to another query.
Maybe one should use params instead? If so, is there any difference in performance?

Regards, Magnus.
