Their API calls are pretty well documented and it's basically a lot of XML parsing. This widget was also built using Robotlegs once I realized that it was really going to be a more invloved module than I initially anticipated. If you wish to compile from source, you will need the Robotlegs .swc file which you can get from the official site. http://www.robotlegs.org/
I have tested some more extensive API calls to Zillow and I am pleasantly surprised that their servies are quick. You are limited to 1000 API calls per day, so if my sample application breaks, that is probably why.
I will update the zip file on the Resource center when new functionalities are complete. The github repo will probably have some incomplete features as I commit often while working.
Any feedback is welcome, thank you.
Update: (02/03/2011) - added search options for Regional Postings to include Property Types and Rentals.
Sorry, I have not had much free time to work on my widget projects. I updated the Zillow widget with a clear button. I've found that users don't always want to clear results when a widget is closed, so I think this is a good compromise.
Now if you wanted to do this on widget close, I add a clear method to the ViewManager vManager.clearLayer(); You can tie the widget close event to a function that can call this method when the widget is closed if you like.
Hope that helps.
Thanks very much for your help! If anybody else is doing this- you can add map.infoWindow.hide(); to the same widgetClosedHandler and it will get rid of any open Zillow info windows when the close button is hit too.
Does this Widget work for Flexviewer 2.5? I have a Zillow API key, but the dialogue box does not open. I've tried the code from this site and from https://github.com/odoe/Zillow-Widget. Thanks!
