FeatureLayer does not honor Marker Line Symbol.

[HemingZhu]

I have a polyline layer symboled with Marker Line Symbol (using Character Marker (Unicode: 233 - looks like "M" as unit). If you displaye as a layer in map service, it works just as it is in .mxd; if I diplay as a featurelayer, the map only honor the color and character size, which results in a big fat line. Do anyone has ideas how to fix or workaround?

The reference for SimpleMarkerSymbol only lists circles, squares, etc so it may be a limitation of symbolising a feature layer?

As a workaround, can you make an image of the "M" and use a PictureMarkerSymbol?

Note that I haven't tried this so it's just a guess (based on the idea that symbolising a feature layer is probably using the same mechanisms as symbolising a graphics layer).

I appreciated your suggestion. SimpleMarkerSymbol and PictureMarkerSymbol are used to draw points and multipoints not polyline. I konw there is no MarkerLineSysmbol class in JS API (as it has in ArcGIS desktop). I was hoping i can get a clear answer of whether it is feasible in JS API to apply MarkLineSymbol on featureLayer.

Unfortunately, if you want to display your polyline data as client side graphics, your options are  SimpleLineSymbol or CartographicLineSymbol. You can use either by creating a symbol and a renderer and specifying your renderer as the renderer for your feature layer.

If you really want use your complex symbology in a web app, you can use a dynamic map service layer.
