Generating and directing new rows in PostExecute.

I want to construct a dataset based on all rows passed in from a source and, upon running through all of them, push each dataset record to an output.

Unfortunately, upon calling the AddRow method, I get an "object reference not set to an instance of an object" error. Am I not allowed to create new rows in PostExecute?

Bill,

Can you post your code, indicate which line the error occurs on, and tell us how you have configured the outputs of the component.

|||It errors on reference to a row buffer.

With dsMaterialBuffer
.AddRow()
'Code for row values
End With

I've added the following to check if it's actually defined within PostExecute;
If dsMaterialBuffer Is Nothing Then MsgBox("dsMaterialBuffer is nothing.") 'My row buffer

dsMaterialBuffer, which is the row buffer I'm using, evaluates to "Nothing" and that is where my object reference errors are coming from.

Is it possible that the row buffers are being thrown out once PostExecute hits?

The outputs, by the way, are non-synchronous with standard columns.|||

What is the name of the output as defined in the inputs and outputs tab of the script component editor?

Hmm, strange. if you want, drop me an email via here: http://blogs.conchango.com/jamiethomson/contact.aspx and I'll reply so you can send me the package. I can take a look and see if anything jumps out.

If you can build the package so that I am able to run it as well (i.e. not reliant on external data sources, just use a script source component instead) then that'd help.
