Re: Thread in DemoLayer

Hi Anoop,

In general, you can't have multiple values for a same key, but you might
try using a scoping prefix to the values you want:

myfirstpoint.lat = latitude
myfirstpoint.lon = longitude
myfirstpoint.name = name
mysecondpoint.lat = latitude2
mysecondpoint.lon = longitude2
mysecondpoint.name = name2

etc.

I don't think you'd want to do this for big collections.

You could also do

myfirstpoint = latitude longitude name

and then use the PropUtils class to parse the space-separated string for
you. That assumes alot from the order of the values, though.
