Dear all,
I try to retrieve features using the WFS-NG module. We do this in
batches of 10 to show it in a table-like grid, and we support paging.
With the old module this worked: we implemented the "paging" ourselves
when the capabilities showed it didn't support an offset. With the new
module, I encounter some weird behavior: according to the
querycapabilities it supports offset (link
<https://github.com/geotools/geotools/blob/75b7dedf87aec993a92e924ccf1d9ac4053a9434/modules/library/data/src/main/java/org/geotools/data/store/ContentFeatureSource.java#L1213-L1220>).
The first 10 (ranging from index 0 - 9) work fine, but the second 10
(ranging from index 10 - 19) yields no result.
The comments say that offset is supported through sorting (in the
capabilities the sorting is supported through a SortedFeatureReader).
But upon inspecting the retrieval of features through the reader, it
doesn't use the SortedFeatureReader (the call to canSort() is true: link
<https://github.com/geotools/geotools/blob/75b7dedf87aec993a92e924ccf1d9ac4053a9434/modules/library/data/src/main/java/org/geotools/data/store/ContentFeatureSource.java#L666-L671>).
The query to the featuresource is:
feature type:
http://flamingo4.b3p.nl/geoserver/Test_omgeving:Test_omgeving:cbs_gemeente_2014
filter: [Filter.INCLUDE]
[properties: GM_CODE, GM_NAAM]
[sort by: GM_CODE ASCENDING]
MaxFeatures is 10
StartIndex is 10
Any idea what I'm doing wrong? Or did I encounter a bug (if so, I'm
happy to supply a patch if someone can point me in the right direction)?
