In Rave Reports version 6.5.0 (VCL10) that comes bundled with Delphi 2006, there is a nortorious bug that plagues many Rave report developers. If you have a non-empty dataset, and the data rows for this dataset fit exactly into a page (that is to say there are zero widow rows), then upon PrintPreview, Rave will get stuck in an infinite loop generating pages.</p> <p>This problem has been previously reported in this newsgroup under the following headings:</p> <ol> <li>"error: generating infinite pages"; Hugo Hiram 20/9/2006 8:44PM</li> <li>"Rave loop bug. Please help"; Tomas Lazar 11/07/2006 7:35PM</li> <li>"Loop on full page of data?"; Tony Chistiansen 23/12/2004 3:41PM</li> <li>reply to (3) by another complainant; Oliver Piche</li> <li>"Endless lopp print bug"; Richso 9/11/2004 4:44PM</li> </ol> <p>In each of these postings, there was no response from Nevrona, and no solution was reported.</p> <p>Possibly, the problem has also been reported on an allied newsgroup (nevrona.public.rave.reports.general), to wit: 6. "Continuously generating report"; Jobard 20/11/2005 Although it is not clear to me if (6) is the Rave Endless loop bug or another problem. This posting did get a reply from Nevrona, but it was more in relation to multiple regions ("There is a problem when using multiple regions that go over a page-break.") than the problem of zero widows.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
