Hi again!
A 'quick and dirty' extension of Location.java to obtain the location from
google based on an address string.
Location.fromGoogleAddress("Selbu, Norway")
Location.fromGoogleAddress("Downing street 1,London,UK");
As long as google can make any sense out of the address it will return a result.
May use xml or json, xml used here.
Dependencies
<dependency>
<groupId>commons-httpclient</groupId>
<artifactId>commons-httpclient</artifactId>
<version>3.1</version>
</dependency>
<dependency>
<groupId>org.jdom</groupId>
<artifactId>jdom</artifactId>
<version>1.1.3</version>
</dependency>
Just an idea.
Cheers
Christian

Subject: Re: isis compile from source, gmaps2 widget?
Just picking up on this thread....
I've been doing some work to resurrect the gmaps widget, and now have it
going.
It does depend on a SNAPSHOT version of wicketstuff-gmap3, so can't be made
part of Isis proper yet.
However, I have created a github repo which explains how to configure it
[1] (with some pretty screenshots).
Also, this needed some updates to wicket viewer itself, so you'll need to
build Isis from source to try it out.
(Jeroen: the fixes I've done here might've sorted out our calendar view,
but I haven't tested it yet).
