[OpenMap Users] csvLinkHandler question...

Hi All:

I'm trying to build a layer containing a series of static locations (lat/lon) that need to be connected with edges. From the API, it sounds like a "csvLinkHandler" would fit the bill!

I'm having trouble getting this to work however. When I turn on my layer nothing happens. I get a message from the CSVLocationHandler saying its trying to figure out the locations and name, but nothing shows up!!!

I tried to follow the "world cities" example...In the openmap.properties file, I created a new com.bbn.openmap.layer.location.LocationLayer and added it to the openmap.layers property (just after demo, but before the shape politicals) I pointed its location handler to a new com.bbn.openmap.layer.location.csv.CSVLinkHandler

I set the properties for my CSVLinkHandler to match my CSV file:

myTest.nameIndex=0

myTest.lat1Index=2

myTest.lon1Index=1

myTest.lat2Index=4

myTest.lon2Index=3

myTest.dashIndex=5

myTest.colorIndex=6

myTest.thicknessIndex=7

myTest.geoStyleIndex=8

myTest.linkTypeIndex=9

myTest.csvFileHasHeader=true

I used the following made up test data and adding cols of ones to cover the other required (though stated as optional by the docs) properties:

CITY_NAMElon1lat1lon2lat2link 1-118.2534-74.140.75link 2-74.140.75-75.218239.92755link 3-75.218239.92755-112.1133.50902

Any suggestions????

THANXS!!!
