Mapviewer SVG and Theme Selection

Question

Im trying to highlight a line by clicking on the line. Im using the svg feature. Here is the xml request im using:
<?xml version="1.0" standalone="yes"?>
<map_request
title="Oracle LBS MAP"
basemap="demo_map"
datasource = "mvdemo"
width="640"
height="480"
bgcolor="#a6cae0"
antialiase="false"
format="SVG_STREAM">
<themes>
<theme name="theme1" selectable_in_svg="true" >
<jdbc_query
spatial_column="geom" jdbc_srid="8265"
render_style="transparent_color"
label_column="destination" label_style="t.street name"
datasource="mvdemo" key_column="origin">SELECT geom, origin, destination FROM flight_geometry WHERE origin ='PHX' and destination ='SDF'
</jdbc_query>
</theme>
</themes>
</map request>
The map is generated a line is displayed however, when I click on the line nothing happens. I set the key column and the selectable in svg attribute. Now when I look at the map, save the svg source to a different file and manually manipulate the featureselect variable in the svg javascript code, view the svg map and click on it it turns red. What is the correlation between the featureselect variable and mapviewer??? Am I not setting a parameter somewhere?? Any help would be appreciated.
Thanks,
Mo

I do not think the feature selection function is available on line features; it is only supported for Area and Point features. we will support linear feature selection/tool-tip functions in the next release.
A possible workaround is to identify a mid-point on the line feature, and place a marker on that mid-point feature. you can then select that point feature and display any information that might be associated with the underlying line.
