Problem to the show report


I've been testing the Fast Report Open Source, but when I fill data, it throw exception:

"Object reference not set to an instance of an object.", StackTrace FastReport.Data.DataSourceBase.RowComparer..ctor (Report report, DataSourceBase dataSource, String [] expressions, Boolean [] descending) ...

// Code

model.WebReport.Report.Load (Path.Combine (ReportsFolder(), "MyReport.frx"));

PostgresDataConnection conn = new PostgresDataConnection ();

conn.ConnectionString = "myconnection";

conn.CreateAllTables ();

model.WebReport.Report.Dictionary.Connections.RemoveAt (0);

model.WebReport.Report.Dictionary.Connections.Add (conn);

model.WebReport.Report.RegisterData (ds.Tables [0], "Data");

model.WebReport.Report.FindObject ("Data"). SetName ("DataReport"); //Name how is in the .frx report

model.WebReport.Report.Prepare (); // when it reach here exception

model.WebReport.Report.Refresh ();

Note: The columns of report are the same of DataTable,

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
