Stuck on error: esri.layers.WMSLayerInfo is not a constructor

TonyAppel1 — Fri, 06 Jan 2012 12:35:53 GMT

Hi all,
Let me preface this with the knowledge that my skills in javascript are "enough to cause trouble" at best.
With that in mind, I have the html block below which has:
1: basemap of a custom tiled map layer using a service that is internal to our company.
2: I am trying to overlay a WMS, non-tiled, layer on top of that.

I keep getting the error below and the WMS layer will not draw or connect. What am I missing or doing wrong?

I have removed some non-map related code so that this will fit in the code block.

Thanks in advance.

esri.layers.WMSLayerInfo is not a constructor

Just taking a quick look, you are calling dojo.require("esri.layers.wmts") and I think it should be dojo.require("esri.layers.wms"). I tested your page and at least saw a call to a web service but wasn't sure what it was returning.

After struggling a few times with this I ended up using AMD require statements and that solved it.

require(

[

"esri/layers/WMTSLayerInfo",

"esri/layers/WMTSLayer",

"esri/layers/ArcGISTiledMapServiceLayer"

function (

WMTSLayerInfo,

WMTSLayer,

ArcGISTiledMapServiceLayer

) {

//Code here

});
