It appears that when a feature is selected with the selection tool, a
filter gets created which contains functions. I beleive this is
happening when the render actually tries to render the selection.
For instance:
<BBOX>
<PropertyName>the_geom</PropertyName>...
</BBOX>
<Or>
<PropertyIsEqualTo>
<Function name="geometryType">
<PropertyName>the_geom</PropertyName></Function>
<Literal>Point</Literal>
</PropertyIsEqualTo>
<PropertyIsEqualTo>
<Function name="geometryType">
<PropertyName>the_geom</PropertyName></Function>
<Literal>MultiPoint</Literal>
</PropertyIsEqualTo>
</Function>

I beleive this is killing the underlying datastores as they dont
understand functions. WFS is the only one that i know of that can and
in this case of the "geometryType" function, it only has a hope of
working with GeoServer since they uses the same function implementation.
I've commented out some lines of SelectionStyleContent which were adding
these filters. Now selection works nicely for a geoserver wfs, but it
remains to be seen why those were there in the first place
(PointSymbolizers had a filter restricting their use to points, but I
would expect a renderer would be smart to realize that PointSymbolizers
are for points)... Unless there are crazy situations where one could
have multiple geometry types within the same feature type. Hopefully I
haven't fixed one thing at the cost of breaking another. This was added
at revision 18962 by jesse -- any thoughts on what the intent was here?
(net.refractions.udig.project/src/net/refractions/udig/project/internal/render/SelectionStyleContent.java)
There is identical code in SLDContent -- and there we have a problem
where when we hit the WFS, visiting all the features a calculating the
min, max, quantile, etc, the datastore just pukes on us... but it does
work on occasion. I had hoped commenting out the same lines would
magically fix things, but we'll have to look at this again tomorrow and
figure out what is really going on...
Cheers,
Cory.
