So why sometimes I can access it and sometimes access violation occur?????? This error is raised when I want to change SQL statement before I preview my report. So how should I change SQL before I open this form??

I write an application with DOA. I have 2 forms. When you click on button on one form then the other raport-form is showing. On raport-form there is component TOracleDataSet. Sometimes before showing raport-form access violation error is raised. TOracleDataSet = nil!!!!! Why? Can sb help...
