Un-necessary/mistaken error msgs when building disease area hierarchy

[kkh451]

When adding dataitems to a disease area (manage disease area) the tree construction process appears to work correctly. However, error msgs complaining of duplicate data items frequently appear when dataitems aren't duplicates.

I didn’t run into any major problems the only thing I did spot was, when I created a data item but wanted to edit the display name, I typed in the new name and pressed OK and the new name appeared. Saved it and then came out of the checklist. However when I went back into the checklist the old display name appeared and not the new one I had edited. It turned out I had to select the data item, remove it and then create a new data item with the correct display name. I thought that was a little long winded.
