FeatureLayer Legend widget issue

TerryGiles — Thu, 15 Aug 2013 22:04:35 GMT

I have a featurelayer in my map which contains polygons with an outline but no fill. It displays in the map correctly, but in the legend widget, it shows up with a black fill (under 'UpperColorado' in the 1st image below). If I look at the legend for the map service's REST endpoint, the symbol looks correct (2nd image).
Any idea how to fix this?

Thanks, TG

Interesting result. Unfortunately, I don't think there is something you can do with the legend dijit result. I would try two alternatives:
1. Use agsjs.dijit.TOC developed by nliu. (http://www.arcgis.com/home/item.html?id=9b6280a6bfb0430f8d1ebc969276b109)
2. It's not too hard to develop a custom one using REST API, especially if you only want to display the legend, not to have it also works as Table of Content.

var layer = new esri.layers.FeatureLayer("http://servername:6080/arcgis/rest/services/test/test_Dis/MapServer/1", {
mode : esri.layers.FeatureLayer.MODE_SNAPSHOT,
opacity: 1.0,
outFields : ["*"]
});

You can use opacity: 1.0 for not displaying fill color in legend....

Thank you Upendra, explicitly setting the opacity as 1.0 solves the problem.
