LoadFromStream: cannot find class Datasets
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,
