Re: [basex-talk] Bug merging maps with option duplicates:combine?

Hi all,

While I don't have any answer to this question, I can corroborate Johannes' finding.

Also, Johannes, did you find a magic string? I tried some longer keys and they seem to work :) Best, Bridger

Hello,

When executing:

map:merge(( map { "DENW21AL100077Hs": "a", "DENW21AL100076i5": "a" }, map { "DENW21AL100077Hs": "b", "DENW21AL100076i5": "b", "DENW21AL100076hT": "b" } ), map {'duplicates': 'combine'})

in the BaseX GUI I get:
