Hello,
I’m getting unexpected results using the Archive module when extracting multiple entries in one call:
archive:extract-text($archive,$entries)
For example what I’m doing is taking an archive with, say, 1000 entries, selecting a subset of those, say 100, and then calling archive:extract-text with that subset.
I’d expect to get 100 results but I get perhaps 97.
I know that all the content is in the archive - if I try to extract one of the missing items directly it’ll be returned. It seems to be an issue asking for lots at once.
Has anyone come across this? What is staring me in the face that I’m missing?
I’ve put a small SSCE at the end of this message that shows the issue - I get something like this returned:
"Entries found: 100 Number of content items returned (bulk): 97 Number of content items returned (individual): 100"
Many thanks for any help.
Regards, James
