Message Action with array parameters

Jul 10, 2011 at 12:37 PM

Hi!

Is there a way to pass an array as Message.Action parameters?
I've a method in the viewmodel wich has an array as parameter like this


Keys(params string[] keys)
{
    //Something
}

and in the xaml I've this

<Button x:Name="Number00" cal:Message.Attach="Keys('D0','D0')" etc../>

when I click that button an exception is raised because the ActionMessage GetTargetMethod function looks for a methods named Keys but with 2 parameters.
I tried to replace the original GetTargetMethod function with this

(from method in target.GetType().GetMethods()
							where method.Name == message.MethodName
							let methodParameters = method.GetParameters()
							where message.Parameters.Count == methodParameters.Length ||
							(methodParameters.Length == 1 && methodParameters[0].ParameterType.IsArray)
							select method).FirstOrDefault();

with this func the method is found but the parameter passed to the methods is always null...

We don't support that. The message parser is fairly dumb for simplicity's sake. We don't support proper overload resolution for that matter either.
