ArcGIS 3.1 for Flex Released

Version 3.1 of both the ArcGIS API for Flex and ArcGIS Viewer for Flex were released on Thursday, December 13.

This is a significant release with many new features, enhancements and bug fixes. The Flex Development Team is very excited to deliver these new capabilities to our Flex users and we hope you’ll be inspired to get started integrating this new functionality. Here are a few of the key new features:

• Support for Attribute Tables
• Viewing and editing related records
• Map rotation
• Local tile package support for mobile applications
• Support for more layer types: CSV, GeoRSS and generic Web Tiled layers
• Summary

Attribute Table Widget and Component
This interactive editable data table is for feature layers and tables. Aside from providing a tabular display of the layer’s data, graphics can be selected, deselected, and zoomed to by interacting with the AttributeTable. If the layer is editable, the feature attributes will be editable and it supports domains and subtypes as defined by the Feature Service.  It is a reusable component in the API and a widget in the Viewer.

_

Viewing and editing related records
The new RelationshipInspector component in the API makes discovering relationships easy. Viewing and editing related records is now supported out of the box in the API through the RelationshipInspector or AttributeTable component and via the Edit widget or AttributeTable widget in the Viewer.

_

Map rotation
The Map component can now be rotated.  There are two sample components included in the API download to support desktop and mobile applications that require map rotation.

_

Local tile package support for mobile applications
The new ArcGISLocalTiledLayer class now supports offline applications that need basemap layers.  Create an Esri tile package (*.tpk) using ArcGIS for Desktop and use the tile package in your Adobe AIR for mobile or Adobe AIR for desktop applications.

_

Support for more layer types: CSV, GeoRSS and generic Web Tiled layers
There are three new layer types to simplify adding operational data to your applications. The WebTiledLayer class makes it easy to add services from standard web mapping tiled layer sources from the web. The CSVLayer class transforms comma separated values files into an operational layer, and the GeoRSSLayer class provides a streamlined workflow for converting georss feeds into layers for the API and Viewer.  See the samples: WebTiledLayer sample, CSVLayer sample, GeoRSSLayer sample.

Developers also still have full access to the Viewer source code on Github - note the new URL – https://github.com/Esri/arcgis-viewer-flex.
