This is the best information I have found so far but I cant seam to convert it to python correctly.

When I save my layout they plugin windows go blank.

Try print the "secret". It's no longer cryptic when you see its actually a dictionary.

I think I am confusing myself. The fact that this attribute is called "secret" makes it impossible to search for with Google.

I tried to print the attribute but of course the secret is not defined. (I am pretty sure I am going about this the wrong way.) Do you know where I can find an example of a python plugin consisting of 2 or more windows?

Sorry, the C++ docs refer to it as "secret", but the Python docs say "sec_ref". I was talking about this parameter, it is the only one passed to RestoreLayout() besides "self".

print sec_ref

{'subid': 0, 'ptr': <PYCObject ...>}

See? Theres the subid.

I'm interested in knowing the answer to this one too.
Since it's much easier to communicate using a working example. Here's a very basic working example showing the problem of not being able to dock a sub dialog:

Hello,

here is an example similar to yours that demonstrates how you can easily restore even sub-dialogs.
It also demonstrates a few techniques that are good practice and useful.

One big problem of your code, for instance, was that, if restoring the sub dialog would have
worked, pressing the button on the main dialog would've opened another dialog than the one
that was restored into the layout.

Also,

a) the subid does not need to be a plugin ID
b) for GeDialog.Restore(), the first argument must be the command plugins PLUGIN_ID,
same when opening the main and sub dialog.

The reason it didn't restore is that the first time RestoreLayout() was called, you create the
sub-dialog, but the second time, the block that forwards the restoring to the sub-dialog isn't
even executed because of

if self.subDialog is None:  # False in the second call
    # ...

Thanks for the help guys, however I still have a few problems. Using Kiklas' method I got the SubDialogs to behave correctly when I re-open them while they are open and the window becomes active. I still get a Plugin not found while restoring a layout, I think this reason is due to having more than one sub dialog.

here is the code:

def Restore(self, PLUGIN_ID, secref) :
     if secref['subid'] == 1:
          return self.sub_dialog1.Restore(PLUGIN_ID,secref)
     elif secref['subid'] == 2:
          return self.sub_dialog2.Restore(PLUGIN_ID,secref)
     else:
          return super(MainDialog, self).Restore(PLUGIN_ID,secref)

How do I correctly look for both subdialogs.

This causes cinema to crash. I will restore the layout but if you launch the sub dialog again everything locks up. This happens with the Example as well. Confused
