nested for each causes pages to diappear

[GoogleCodeExporter]

What steps will reproduce the problem?

1. Create page at top level A
2. Create child page under A called B
3. Create child page under A called C
3. Create child page under C called D
4. Create child page under C called E

Thus the page structure will look as follows:

A
-> B
-> C
---->D
---->E

Now, on page A use velocity to create a for each loop to display content of 
each child, in this case this would be content of pages B and C.

In page C content, create a velocity for each loop do display content for each 
child, in this case this should be content for pages D and E. 

What is the expected output? What do you see instead?

Thus when displaying A, you should see content for all pages in the tree. 
However, what actually happens is that the page C content and children don't 
show up at all. Further, there is no way to restoring page C, other than 
deleting it and re-creating it from scratch again.
