OutOfMemoryException when printing empty databand

[WalterJKR]

Hello Stimulsoft,

One of our reports stopped working with recent versions 2015.2 and 2015.3 of Stimulsoft Ultimate (WPF & .NET). The attempt to print or preview the report ends with OutOfMemoryException with callstack attached bellow. I managed to find out that the problem is in child databand pasted into panel in master databand, which contains no rows. We updated the report and set Panel1 holding Databand2 condition to "StandardniPrijataObjednavka.RadekSet.TypPolozkyVRadku != TypPolozkyVRadku.Sortiment" which disables printing of the databand when there is no row to print. Everything works and the report is printed/displayed successfuly. I have uploaded both broken and fixed reports (.mrt) as attachment.
(excuse czech language in the code, it's only for technical purpose when looking at the reports)

As I mentioned, the broken report worked in one of the previous versions we had installed. Also, we managed to add condition allowing to print without problems. I report this only for you to find the bug and fix it in the future versions.

Thank you.
JW

Hello,

We couldn't reproduce this issue.
Can you please send us a simple test project, which reproduce the issue, for analysis?

Thank you.

It will take some time but I'll try.
