FeatureLayer and Simplerenderer

[rb7smutje]

Hi,
Just checked the DirectionalLineSymbol with a FeatureLayer and Simplerenderer, works fine. However there is a minor problem, after panning (draging) the map the PictureMarkerSymbol is vanishing, only the line stays visible. Only after changing the map scale (zoom), the PictureMarkerSymbol comes back.
`
var Link = new FeatureLayer("http://XXX", {
mode: FeatureLayer.MODE_ONDEMAND,
outFields: ['*']
});

	            var picSymbol = new PictureMarkerSymbol();
                picSymbol.setUrl("javascript/filled-arrow.png");
                picSymbol.setHeight(12);
                picSymbol.setWidth(12);

                //add a basic polyline
                var basicOptions = {
                    style: SimpleLineSymbol.STYLE_SOLID,
                    color: new Color([0, 0, 0]),
                    width: 2,
                    directionSymbol: picSymbol,
                    directionPixelBuffer: 40,
                    showStartSymbol: true
                };
				var basicSymbol = new DirectionalLineSymbol(basicOptions);
				directionalSymbols.push(basicSymbol);
					        
				Link.setRenderer(new SimpleRenderer(basicSymbol)
							);	
				map.addLayers([Link ]);`

Thanks for efforts!
Greets,

Hi @rb7smutje, can you set up a plunker, jsfiddle or anything else to demonstrate the problem live? Will make it much easier to have a look!
Thanks,

Hi Nick,
there it is:

I've made a workaround, refreshing the layer after every pan.

mapV.on("pan-end", function(test,lala){
Link.refresh();
//Link.redraw();
});
Thanks,
Regrads,

Hey @rb7smutje, have had a quick look and can see what you mean. Pretty sure you have found the fix for feature layers. Appears to be some difference on the extent-changed event handler for Feature layers and graphics layers....or a difference when using the symbol in a renderer, but I never had any issues when testing using graphics layers.

I'm going to close this as you have a solid workaround for feature layers. Thanks for figuring that out!
