I'm trying to get point features ( in a vector kml layer) size to scale with
an attribute value named "Water_Leve"
I tried to test this in Firebug like this:
map.layers[1].styleMap.styles.default.defaultStyle.pointRadius='${Water_Leve}';
and got the error message:
Unexpected value ${Water_Leve} parsing r attribute.
I think that the attribute may have been registered as a string when i
created the kml file from a shapefile earlier (is there a quick way to check
the data type of an attribute in firebug?)
So i tried to convert it to float on the fly like this:
map.layers[1].styleMap.styles.default.defaultStyle.pointRadius=parseFloat('${Water_Leve}');
and got the message:
Unexpected value NaN parsing r attribute.
Can someone help me get this right?
Thanks,
Vishal
