Version 3.0i - 5 Sept, 2012

• Recompiled for Flex Viewer 3.0 with no locale specified

Version 3.0 - 13 June, 2012

• Recompiled for Flex Viewer 3.0
• Fixed some disableZoomMenu option issues

Version 2.5.1.1 - 7 May, 2012

• Fixed bug with sublayers having a description option when usenewesridescription is true.

Version 2.5.1 - 4 May, 2012

• Fixed bug with loading legend remaining when there is no operational layers or when a WMS layer is used or when a layer fails to load due to some error.
• MAJOR CHANGE when a layer of a map service or the whole mapservice is excluded using the excludelayers it is excluded from the TOC and the map. This has changed from where it use to be visible in the map even though it was excluded from the TOC. Clarification If you want to exclude a whole map service from the toc and the map then you just remove it from the viewers main config. Currently if you exclude a map service and do not specify any sublayers then the mapservice will remain in the map.
• Mapservices are ordered in reverse order of what you have in the main config.xml, just like esri's layerlist and map switcher.
• There is a new 'everything' attribute on the tocsettings expanded tag. This forces all layer/sublayer/legends to be opened. If you use the everything="true" attribute than the collapselegends is ignored. There are still situations where a map service will fail to expand due to some network delay occurring for that map service.
• Individual Layer of a Map Service now have a TOC menu for zooming to its extent.

Version 2.5.0.2 - 23 Mar, 2012

• Added support to mimics esri's concerning hiddenLayers_ being removed automatically from the TOC
• Added support to mimics esri's concerning updating the TOC when programmatic changes to layer visibility is made.

Version 2.5.0.1 - 27 Feb, 2012

• Fixed the issue where featurelayers are always added to the top of the TOC. Now featurelayers are added in the exact order that they appear in the config.xml.

Version 2.4.2 - 1 August, 2011, 8:40 PM

• Fix for the disappearing labels
• TOCWidget now respects what has been set in the MapSwitcherWidget and vise versa.
• Minimal support for KML layers has been added. Legend swatches are not supported yet as the API's support of KMLLayer is not matured yet.

Version 2.3.9.2 - 1 August, 2011, 8:40 PM

• This probably will not happen ever again but I wanted to have a good stable Flex Viewer 2.3.1 version of this widget available so I have added the compiled version with the memory leak fix and the follow-up fix for the disapearing labels.
• Uncompiled code is written for Flex Viewer 2.4 ONLY!

Version 2.4.1 - 1 August, 2011, 3:10PM

This is just a simple TOC Widget that includes my dynamic legend component. This widget also includes my enhancement for map service transparency, right click context menu for zoom to make layer visible, and my scale dependent renderer for the TOC checkboxes.

To install using the compiled version just copy the folder called TOC under the Widgets folder, and add this line to your config.xml

For the Uncompiled you need to copy the TOC folder to src/widgets then add TOCWidget.mxml to your flex projects modules list, and compile your project as well as add the widget line above to your config.xml.
