Google map addon

Mr16 · November 26, 2012, 2:20pm

I’m currently trying the app out at a cloud service (CloudFoundry) but got this error when trying to paint markers on the map:

I’m using a custom application servlet extending AbstractApplicationServlet and
everything works fine on a local jetty or tomcat server
.
Any ideas what’s wrong?

Paul115 · January 14, 2013, 10:38pm

Are there plans to release a version compatible with Vaadin 7 in the future?

Arthur11 · February 4, 2013, 12:03pm

Hi Sir,

I would like to know if there is a way to differ an one-click event from a two-click event when the user clicks on the map. Is it possible yet?
I apologize if I’m doing something wrong. I’m sort of new to this forum.

Thanks,

Arthur J.

sam35 · March 16, 2013, 8:27pm

VAADIN 7, Talk to me?

Henri · March 17, 2013, 6:36pm

Yes, I plan to migrate the add-on to Vaadin 7 and fix at least some of the known issues as soon as I find a few days to work on it. I don’t have an ETA though, so if you really need it you should contact to sales@vaadin.com.

F1113 · May 20, 2013, 7:33am

What is the news on Vaadin 7 support?

Henri · May 22, 2013, 7:05am

Still no ETA, sorry. We’re extremely busy with other stuff, so I’m afraid hobby projects remain on the back burner.

Abbas3 · July 23, 2013, 6:26pm

For people like me who really wanted an integration of Vaadin 7, I recently developed a simple component that integrates Google Maps v2 with Vaadin 7:

https://github.com/asarraf21/GoogleMapsVaadin7

It is not complete by any means, but it is a very good starting point to add your own functionalities.

Salman2 · July 26, 2013, 9:21am

Hello Sir,
Let me tell whether Google map Add on supports if I give Address in String format E.g: I have Address ‘45 Lawrence Ave
Lodi,07644 New Jersey, United States’ so can I find the location using this add on in vaadin

Henri2 · July 26, 2013, 10:07am

Please do not post duplicate questions. I tagged your other post for deletion.

To convert addresses to coordinates, you need to use a geocoding API - e.g.
Google has one
and there should be others available. It is not related to this Vaadin add-on, and you can use it directly from the server side. Note that there are limits to how many free queries you can do per day.

Salman2 · July 30, 2013, 7:13am

thanks sir…

Henri · August 15, 2013, 11:38am

Just to let you know about availability of a
Google maps add-on
by Tapio Aali that supports Vaadin 7 and maps API v3. It’s not a upgrade to this add-on but instead a full rewrite, so the API is a bit different. Most of the features are still there, though.

The work was partially sponsored by several companies, but the add-on is still available under Apache 2 license.

This means that there will probably be no (unsponsored) updates to the old add-on.

Kiren · September 26, 2013, 2:54pm

Hi Henri,

I’d like to have multiple colours for my markers, how can I achieve this?

Manuja · November 20, 2013, 4:33am

Hi All,

Need urgent help. I used this widget for number of applicaitons and now its not loading the map since today morning. I just check your online demo and its also not working for me. Appreciate your help to solve this matter.

Thanks,
Best Regards,
Manuja

Xander2 · November 20, 2013, 10:58am

Hi,

Having Exacly the same problem as of today.

Manuja · November 20, 2013, 12:14pm

Xander Zaaiman … Please let me know if you get any solutions for this.

Thanks

Fulvio · November 20, 2013, 2:06pm

Look this : https://developers.google.com/maps/documentation/javascript/v2/

Henri · November 24, 2013, 8:13am

As mentioned by Fulvio Google has deprecated the Google Maps API v2, which this add-on requires. Please migrate to the new add-on ASAP. More info: https://vaadin.com/forum#!/thread/3802318

Manuja · November 24, 2013, 8:35am

Thank you very much guys.

I did migrate my applications in to vaadin 7 and now using
https://vaadin.com/directory#addon/googlemaps-add-on
.
