Hi Bert,

sorry for not getting back to you sooner. I've been thinking quite a lot about this.

I was about to write "Sorry, neither MetaMod nor MetaTemplate address changing the Default Menu Item", but I decided to look inside Joomla just to check how hard it would be... and found that it may not be so difficult after all

Now, I don't know if this is going to work any better than the Virtual Domains extension, regarding the issues that you cited. However it's worth a try.

Essentially, all you need to do to switch the "default menu item", is to get hold of the relevant menu item id from the Menu Manager. Then, use the following code inside the PHP box in the SUCCEED or FAIL actions in MetaTemplate(/Pro):

$menu = &JSite::getMenu();
$menu->setDefault(XXX);// replace XXX with the menu id (Itemid) of the menu item that you want to be default.

This should make it super-easy to set the template and the default menu item for any rule, using MetaTemplate(/Pro). You can then use MetaMod to change the modules for any given template, so that takes care of the modules too.

I hope it shouldn't be too hard to design a rule that switches to the PrimaryDomain when CB registration is accessed. You could detect it with the "Page URL" textbox (or perhaps the Domain and/or Component depending on your needs), then with the SUCCEED rule switch to an alternative URL.

Hope all that helps,
I'm considering building in a "change default page" control to the next version of MetaTemplate(/Pro) as it's such a great idea! (thanks...)
