If you’re using Domino Access Services to get a view entry collection and include the count=XXX parameter (like described here), you’ll get an error if the number is larger than 100:
Limit exceeded. Cannot read more than 1500 entries.
According to this, this limit was introduced with the 901v00_10 version of the Extension Library. I just ran into that limit myself and decided to do some digging in the ExtLib source. In one of the source files I found that the maximum can actually be controlled by a notes.ini parameter called DataServiceMaxViewEntries.
I just set that on my server and it works like a charm!
(not sure if this is a supported parameter, or if it will remain in the ExtLib, so you’re on your own with this…)
