Copying functoids from one page to another

A question was asked about one of my previous post http://connectedpawns.wordpress.com/2009/10/10/copying-functoids-from-one-map-to-another/#comments. The question was can you use the same method to copy between pages on the same map. I did a bit and yes you can.

I created a test map and added blank second page like this;
After saving I shutdown Visual studio. Next I opened the TestMap1 from the file system and it looks like this;

Copy the text lighted above. Highlighted from page 1 to page 2.

Save the file and close it.
Open the project in visual studio.
Save the altered map before doing anything else.
Re-open the map file in at ext editor. Note at the LinkID’sand the FunctoidID’s have been magically re-numbered on th.e second page. The GUIDID’s for the functoids have not changed but this seems to make no difference to how the map works. I have even changed some of the inputs in the functoids on the second page and everything was still OK. At runtime the map also did what it was supposed to.

As a further experiment I tried copying the links within the same page to see what happens. This does not work because the map editor cannot re-number the links.
