If there is nothing in the FeatureSet tag, it is likely because the
FeatureSource has no
primary key. I have not used WFS enough to comment on wether it is a problem
with the WFS server, the provider, or your setup.
You cannot select items from FeatureSources, if the FeatureSource has no
primary key.
You may be able to force a column to be the primary key if you use
Maestro (untested :)).

Dear all
I've modified the PHP sample (Ajax viewer) to show an SDF layer and a WFS
layer.
If I drag-select in the SDF layer, objects are selected (highlighted) as you
would expect, and the Properties pane is updated.
But, if I drag-select in the WFS layer, nothing happens.
The XML returned by the QUERYMAPFEATURES on the SDF layer:
<?xml version="1.0" encoding="UTF-8"?>
<FeatureInformation>
<FeatureSet
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:noNamespaceSchemaLocation="FeatureSet-1.0.0.xsd">
<Layer id="1f7704ee-0000-1000-8001-001ec9e5fedc">
<Class id="Default:10kmGrid">
<ID>dwgAAA==</ID>
</Class>
</Layer>
</FeatureSet>
<Tooltip>SJ99</Tooltip>
<Hyperlink />
<Property name="..."/>
...
</FeatureInformation>
The XML returned by the QUERYMAPFEATURES on the WFS layer:
<?xml version="1.0" encoding="UTF-8"?>
<FeatureInformation>
<FeatureSet
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:noNamespaceSchemaLocation="FeatureSet-1.0.0.xsd">
</FeatureSet>
<Tooltip />
<Hyperlink />
<Property name="..." />
...
</FeatureInformation>
In other words, the <FeatureSet/> element is empty for the WFS layer.
Presumably this is what's preventing the object being highlighted and the
Properties pane being updated.
Can anyone explain why the XML structure is different?
Many thanks
Stuart
