Hi,
You're denoting this as a repeating group for the mapping, with the base node being my:myFields/my:TaskItems/my:group2. I believe the problem is that, within that mapping, you are using an absolute path, which is not going to work.
So if the xpath to the repeating group is my:myFields/my:TaskItems/my:group2, and you add a mapping for my:myFields/my:CorpEvents/my:Title the command ends up looking for my:myFields/my:TaskItems/my:group2/my:myFields/my:CorpEvents/my:Title, which of course does not exist.
Instead of using the absolute path, use a relative path. i.e. instead of my:myFields/my:CorpEvents/my:Department use ../../my:CorpEvents/my:Department.
That way, the form goes to look for that xpath, it'll result to:
my:myFields/my:TaskItems/my:group2/../../ (which brings us back to the root, my:myFields) and then my:CorpEvents/my:Department.
I believe you'll have to enter those paths manually because the form won't let you select a node outside of the repeating group.
Does that make sense? Please try it out and let us know how it goes. Thanks!
