[Chameleon] Chameleon 2.6 beta1 release

Fri Jul 20 13:31:24 EDT 2007

Hi everyone,

After nearly a year without a release it's about time! There was a lot 
of development on the JSAPI end and some new widgets added. Check it out!

Big thanks to everyone involved in Chameleon in the last year either for 
development or just by being present on the mailing-list.

Here's a summary of what's new in 2.6:
-------------------------------------

A new QueryByShape widget to do simple queries using a simple feature 
from a predefined layer. Currently only polygon layers are supported.

A new ChartLayer widget to add basic charts on a map

New set of widget that include digitization in Chameleon with the help 
of PostGIS. Specify a PostGIS layer to add the new feature in and draw a 
new feature with the ROI tools, then simply click Digitize.

Add the support for query results in two frames one for general results 
the other for detailed results.

Add JSAPI support for the following widgets:
SECTPopup, LinkQuery, MapSize, MapNotes, LayerLabels, WMSBrowser, 
ExtentHistory, UpdateMap, MapTips, Table, LayerOrder

A lot of bug fixes and much more...

defined on-the-fly for point and line layers.

cwc_roi.js: fixed up issue from bug 1522 (CWCROIManager_TriggerEvent did 
not deal with arguments properly, because method wasn't set up for it; 
copied body from triggerEvent method out of cwc_events.js)

ROIPolygonTool.widget.php: fixed up two issues from bug 1135 (ROI 
JavaScript object in array got destroyed when a new ROI was created, due 
to pass by reference) and bug 1610 (any keypress other than escape 
caused an attempt to close the polygon, resulting in JavaScript error if 
no nodes had been created yet)

LocateByAttribute/searchresults.phtml: Put in temporary patch for the 
PostGIS workaround, due to mapserver quotes bug described in "Filter in 
Mapserver 4.10.0" thread on MapServer DEV list

LocateByAttribute/searchresults.phtml: Modified it to wrap around 
MapServer query functionality (but does not depend on layer having 
template set). This allows searching of all formats that hold 
attributes. PostGIS implementation has a slight work-around because 
QueryByAttributes behaves differently for PostGIS. This may need to be 
reverted if QueryByAttributes is changed. Tested successfully with SHP, 
TAB, DGN, ESRI geoDB, and PostGIS. Added option to only search within 
current extent.
