Unable to handle nested dictionaries

[mjohnson9]

While attempting to implement the Protocols property from the org.freedesktop.Telepathy.ConnectionManager interface, I ran into the fact that IDictionary<string, IDictionary<string, Parameter>> results in a System.ArgumentException: The type of an array must be a single complete type.

Is this intended, or should the library be capable of handling nested dictionaries?

I got the same issue with the method 'GetSettings()' from 'org.freedesktop.NetworkManager.Settings.Connection'.

Did you find a workaround?

I randomly replace the method content of Signature.MakeDict(..) :

return MakeArray (MakeDictEntry (keyType, valueType));

by

return MakeDictEntry (keyType, valueType);

And it seems to work, but I can't guarantee that's the right solution. A project developer has to confirm this.

I have the same issue. I have the following connman DBus method:

<method name="GetServices">
     <arg name="services" type="a(oa{sv})" direction="out"/>
 </method>

With the NDesk implementation, the following worked:

IDictionary<string, IDictionary<string, object>> GetServices();

I made the change that Ummon recommended and everything seems to work now as well. If this isn't the right way to code the interface method, then what would it be?
