I created a Merged WebHelp project containing App1 and App2
I did generate and Save and then view. All works great, I get root node and two children: App1 and App2
Problem is, as soon as I go into App1, I can no longer get back to root
What am I missing?
Not sure here.
See if the pages on my site help. Once the merged help is generated it functions as if it were from a single project. Have you generated all the children that the parent knows about? You have to publish them all before it works properly. After that you can delete the output for a child and it will still be OK, but not until you have generated all of them once.
