TreeGrid DataBinding - Client-side Data Integration

[ADA]

I have a server that provides XML response over HTTP. I need to bind this XML response to a TreeGrid. I went trough the SmartClient Reference 6.5.1 regarding Tree DataBinding, but was not able to find a solution.

Following the examples provided in the SmartGWT Showcase I am able to build a tree from data in an XML file stored locally. ( http://www.smartclient.com/smartgwt/showcase/#tree_appearance_connectors )

Can anyone please provide sample code on how to DataBind a TreeGrid with data coming as XML response from a server. (This is a starting point.. ultimately I am trying to build a tree with varying node types, something similar to http://forums.smartclient.com/showthread.php?t=65&highlight=TreeGrid+Databinding )

The above sample does data bind to xml from the server over HTTP. It's just that the sample users a static xml file on the server. You can have the datasource dataURL point to your http path that serves up the xml dynamically.

browser same-origin policy issue

If I point the DataSource DataURL to the http path that serves up the xml response, I get the browser same-origin policy issue.

"SmartClient can't directly contact URL due to browser same-origin policy use XJSONDataSource for JSONP protocol or use the server-side HttpProxy included with SmartClient Server."

You cannot load xml from a different domain due to cross domain restrictions. The only way around it use a server side proxy servlet. You can search this forum or Google for more info on cross domain restrictions of ajax.
