[mono-android] Problem with setting of EditText.TextChanged

[Michal Sartoris]

Hello,



I'm having problems with adding TextChanged event handler to EditText. It is randomly crashing with this exception:



E/mono    (12288): [0xafd4a830:] EXCEPTION handling: System.InvalidCastException

: Cannot cast from source type to destination type.

I/MonoDroid(12288): UNHANDLED EXCEPTION: System.InvalidCastException: Cannot cas

t from source type to destination type.

entArgs>) <0x0002b>

I/MonoDroid(12288): at Android.Widget.TextView.add_TextChanged (System.EventHand

ler`1<Android.Text.TextChangedEventArgs>) <0x0004b>



My code:



_textField.TextChanged += (s, e) =>

                    {

                           var fn = FilterChanged;

                           if (fn != null)

                           {

                                  fn(this, EventArgs.Empty);

                           }

                    };



This is working most of the time, but sometimes it crashes. Any suggestions or should I submit a bug report?



Best regards,
