LoadFromStream: cannot find class Datasets

Hi,

when I try to run TfrxSubreport.Page.LoadFromStream I always run into the exception: "raised exception class EClassNotFound with message Class Datasets not found". Attached you can find the zipped fr3-files that I use to dynamically create a report.

• ProjectProtocol.fr3 -> inherits from ReportBasic.fr3
• ReportProjectProtocol_Group.fr3 -> will be dynamically loaded as a subreport
• ReportProjectProtocol_Series.fr3 -> will be dynamically loaded as a subreport
• Resulting-Report.fr3 -> is the resulting report after dynamically load all parts together

The data will be collected using the callback methods of TfrxUserDataSets.

Also in the attached zip-file there are screenshots where you can see how the FastReport Designer shows the resulting files when I load it manually.

Looking forward that anybody can contact me, so that I can learn more on using FastReport correctly and errorless.

Many Thanks for your support,

Adrian
