Creating reports and dashboards | Stimulsoft community forum

Hello,
i have used the trail version of the Ultimate version to create some reports with classes published
from a wcf Service. In the configuration of the WCF Service I set the "List-Datatype" from Arrays to
ObservableCollection(setting.png). So .. in the Trail version everything works fine ...
Now we have bought the Ultimate version and ObservableCollection no longer work ...
In the designer everything is fine even the preview works, but if i want to show
the report it crashes -> Unbenannt.png
StiReport report = GetNewStiReport();
report.Load(this.Data.SelectedChoose.FilePath);
report.RegData(_DataStoreName, _data);
report.ShowWithWpfRibbonGUI();
//report.Show();

thats annoying because the trail version works!
So I tried to set the List-Datatype to Generic.List and it works ... but all my reports are broken now and I have
to rebuild those

Hello,

Please download the new version again. For technical reason the new version has been reloaded. Sorry.
If it is does not help please send us a sample project which reproduces the issue for analysis.

Thank you.
