Hi Thiago,
I realise that I will need to use JavascriptSupport and an imported .js
file to achieve this. My question is about generating the JsonObject
serverside which will be used in JavascriptSupport.addScript(). I need to
have a javascript string containing the infowindow html (see
http://code.google.com/apis/maps/documentation/javascript/overlays.html#InfoWindows
).
I'm guessing that my JsonObject will look something like
{
markers:[
{latitude:xxx, longitude:yyy, infowindowhtml:'<div>marker 1
title</div><div>marker 1 body</div>'},
{latitude:xxx, longitude:yyy, infowindowhtml:'<div>marker 2
title</div><div>marker 2 body</div>'},
{latitude:xxx, longitude:yyy, infowindowhtml:'<div>marker 3
title</div><div>marker 3 body</div>'},
]
}
So I need to generate each infowindowhtml using tapestry's templating
engine to merge the current marker object with the template (passed as a
parameter to the component).
