Hello again!<br>
<br>
I'm trying to allow for any records with a NULL property to be
returned via a WFS 1.1 GetFeature request. <br>
OpenLayers has a OpenLayers.Filter.Comparison.IS_NULL filter that
produces XML such as:<br>
<br>
<ogc:PropertyIsNull><br>
<ogc:PropertyName><br>
YEAR<br>
</ogc:PropertyName><br>
</ogc:PropertyIsNull><br>
<br>
MapServer (6.4) however doesn't support it, and logs the following
error: msWFSGetFeature(): WFS server error. Invalid or Unsupported
FILTER in GetFeature<br>
Looking at the page <a class="moz-txt-link-freetext" href="http://mapserver.org/ogc/filter_encoding.html">http://mapserver.org/ogc/filter_encoding.html</a>
page it seems all 8 tests fail for this filter:<br>
<br>
1.3.4.10 GetFeature PropertyIsNull filter<br>
<br>
And in the notes below "Test number 1.3.4.10: This property is not
supported in MapServer."<br>
However several recent commits seem to reference this filter e.g.
<a class="moz-txt-link-freetext" href="https://github.com/mapserver/mapserver/commit/7c97d948645e3c04228e25ba2f5333f0a23fd128">https://github.com/mapserver/mapserver/commit/7c97d948645e3c04228e25ba2f5333f0a23fd128</a><br>
Is this for WFS version 2.0? Is so are there any plans to implement
PropertyIsNull for older WFS protocols?<br>
<br>
Regards,<br>
<br>
