Hi Lance,
in fact, in my sample (Eiffel Tower example), i put html content into
properties file but you're right : i agree that this could be easier to
directly use block binding parameter or the GMap api support for passing the id
of a
html element.
I'll try to add this feature in the next release.
Tanks for your feedback.
Laurent

Hi Laurent,
I took a look at your library and from what I can see, it is missing the
functionality that I want. It seems that each marker has an info property
which is a string containing the text to render in the info window. I would
like each marker's info window to contain complex html and I would like to
achieve this by passing a block (or perhaps a render command) to the gmap
component which will be used to render each marker's info window.
I have noticed that the google map marker api supports passing the id of a
html element instead of the text content to show for an info window. I
think I will explore the option of rendering a hidden div for each marker's
info window using a RenderCommand parameter and the MarkupWriter. I will
then pass the div id's to the gmap's javascript initializer so that the
info window div can be shown when a marker is clicked.
Unless, of course, someone can tell me how to use tapestry's templating
engine to render strings on the serverside which I can pass to the
javascript initializer. I'm thinking that tapestry must be doing this
somewhere in order for MultiZoneUpdate to work?
