Removing a mapping element breaks import

Hi

I've noticed that if I remove a mapping element from an existing feed importer, it no longer imports properly.

For example:

I have an importer with 4 mapped source elements (using XPath XML Parser):

xpathparser:0 Title
xpathparser:1 Body
xpathparser:2 Code
xpathparser:3 GUID

I do an import, everything working fine.

Then I decide to remove one of the elements:

xpathparser:0 Title
xpathparser:2 Code
xpathparser:3 GUID

The next time I import, only the first element will get mapped to source data. In the debug view, the second and third elements don't get mapped to anything. It's as if Feeds hits the deleted entry and can't process any further.

I think this is a Feeds issue rather than Xpath XML Parser..?
