  Hi Jose
  
  I'm having a similar problem adding a TfrxUserDataSet by code. I have a TfrxUserDataSet on the form so it is installed and can be found but still won't work...
  
  If I find a solution to my problem there will be a similar fix for yours.

  Try to compile FRDemo. Did you get same result?

  Try adding a RegisterClass(TfrxDBDataset) to the Create() of your Delphi application... let me know if this works for you.

  I found a possible cause:
  
  If the implementation section of my code is like this:
  
  implementation
  
  uses System.TypInfo, System.IOUtils, System.StrUtils, System.Types, System.Variants, System.DateUtils,
  FMX.Dialogs, FMX.Forms;
  
  {%CLASSGROUP 'FMX.Controls.TControl'}
  
  {$R *.dfm}
  
  The form editor shows the error "Class TfrxDBDataset not found." and eliminates from the visual form all the components.
  
  Instead if I change this part, to show like the next block, all works well:
  
  implementation
  
  {%CLASSGROUP 'FMX.Controls.TControl'}
  
  {$R *.dfm}
  
  uses System.TypInfo, System.IOUtils, System.StrUtils, System.Types, System.Variants, System.DateUtils,
  FMX.Dialogs, FMX.Forms;
