When searching for records in an SQLite database and importing these records in
a class that inherirts from Data.Datatable I get the following Error Message:

frmSearchText.btnSearch_Click Import Row System.Data.DataRow
System.InvalidCastException: Cannot cast from source type to destination
type.

without mono this works fine! What can I do?


Reproducible: Always

Steps to Reproduce:
1.Download
http://downloads.sourceforge.net/repetitnettsqli/Repetit.Net.T.Mono_0_6_0_12.tar.gz?use_mirror=garr
2.Enter Data in Database
3.Call Suche:Textsuche and enter some Symptoms that are in the database. Check
"Symptom", "Leitsymptom", "Beschreibung" and press "Suche"
Actual Results:  
System.InvalidCastException: Cannot cast from source type to destination
type.

Expected Results:  
The results are imported in a class that inherits from datatable and are shown
in a treeview.

It is a great problem that the application framework does not work, so every
bug causes a crash. The code in ApplicationEvents.vb is not executed!
