Error message:

The problem is that the command of Contextmenu is finding the ICommand DataContext.RemoveFolderCommand for 2 reasons.

1- I use the same Binding just below it : <Behaviors:CallMethodAction MethodName="SelectedFolderChange" TargetObject="{Binding RelativeSource={RelativeSource AncestorType={x:Type Page}}, Path=DataContext}" />, Out there are 4 more commits in my shampoo and they all work.

2- That command performs correctly if the following happens: If with the application running, I edit the "Hot relaod" shampoo, for example by removing the Mode=FindAncestor the command Contextmenu works normally again, so if I re-load the application it stops working again. Soon if I run the application again and again edit the command adding again the Mode=FindAncestor the command back to work, and if I give Reload again in the application it stops working until I edit again.

In short, I have one command that only works when I edit it in the shampoo while the application is running.

Does anyone know how I can fix this?

I have tried: To use the visualstudio, To use the blend, Restart the two programs, Restart the Machine, Rewrite that part of the code.
