Dummydata for signals / dummydata for attached properties

ephe

I have implemented some attached properties in C++ which work perfectly fine in QML.

Now our designers would like to use these QMLs too. But they do not have access to the C++ code.
Therefore I wanted to create some dummydata.

I created the dummydata folder and a qml file MyAttachedProps.qml:
@
import QtQuick 1.1

Item {
property string prompt: "my control"
}
@

When I use MyAttachedProps.prompt in the real QML file, it is replaced with the prompt of the dummydata.
The output is: Loaded dummy data: "E:/Pegasus_Screen_Components/dummydata/ComboLineCtrlProps.qml"
So for simple properties, this is working fine.

I now also have a signal in C++: mySignal, which would be called like this: MyAttachedProps.onMySignal: ...

I don't know how I can put this in the dummydata? The output is:
@
file:///C:/MyProject/MyControl.qml:67:5: Non-existent attached object
MyAttachedProps.onMySignal: ...
^
@
What am I doing wrong?

And what do I have to do that the "import MyModule 1.0" is recognized? The output there is:
@
file:///C:/MyProject/MyControl.qml:3:1: module "MyModule" is not installed
import MyModule 1.0
^

Thank you!

I could solve the import problem. The solution is "here":http://developer.qt.nokia.com/forums/viewthread/14913. But I still have the same problem with the attached properties.
Maybe someone can help me?
