Description yeray alonso 2014-03-27 11:23:42 EDT 
A customer finds that the series datasource list for the functions in the editor is empty.
Two projects attached: An MDI and a DLL.
Instructions:
1. After compiling both modules, run the MDI. The MDI processing will initiate the Form processing that contains the chart. The form is located in the DLL. (I am not sure the DLL has anything to do with this, but I included as I use it).
2. Double click on the chart to open the ChartEditor.
3. Add a Line series.
4. Add a Function series (like Add).
5. Go to the Data Source tab for the Function. The series is missing.
Note: If you comment out the call to Replace_Chart in DLLUnit, and recompile, it will work correctly. The problem has something to do with the chart replacement.
I have found a detour this problem. The issue has to do when attaching one form to another. If the latter form has the DBChart and the parent one does not, it will fail. If the parent has a DBChart of any kind (even if hidden), it all works.

Here it is the workaround the customer found. But this seems not to work any more 
in v2014.10:

"Just to get you up to date. I have found a detour this problem. The issue has to do when attaching one form to another. If the latter form has the DBChart and the parent one does not, it will fail. If the parent has a DBChart of any kind (even if hidden), it all works."
