Problem when NoData
When designing the report, i'm setting the autosearch values to
something that results in NoData. when i preview the report i'm
getting the wanted blank page. When pressing the spy-glass to provoce
the autosearchvalues dialog i'm pressing OK, still get the blank page.
When i run the same report over a server the server is crashing in a
OnCalc value where i am referenceing a field. It is correct, the
field, or better, the dataset has no values, but why in the IDE i'm
getting no crash and in the server i'm getting a error.
Kind Regards

On the Server the NoDataBehaviors settings for ndBlankPage and
ndDisplayDialog are not supported. Instead ndBlankReport is used.
This is necessary because ndBlankPage does not result in any TppPage object
being created. In a server environment this results in the client waiting
infinitely for a response from the server. The setting ndBlankReport
generates an empty report page that is sent to the client.
In your OnCalc try checking for the no data condition. One simple way is to
check
if myPipeline.Bof and myPipeline.Eof then
{no data}
