Pipeline for Native IBO Components
Hi all,
I started to write a new pipeline for native IBO components (not TDataset
descendent). I managed to do most of the work. Still, i have a problem when
i try to preview the report. I get en AV error. Can someone tell me what
exactly happends when preview is activated because i don't know where to
look for the problem. In design mode everything is OK, i can see fields, and
if Dataset is opened i can see values in fields, but on preview i get an AV.

Compare your IBOPipeline code to TppDBPipeline (ppDBPipe.pas).
The report engine traverses data by using the Next, Prior, Last, First
methods and also the GetBookmark and GotoBookmark methods. Make sure you
have implemented book marking in your pipeline.
