How do you add multiple points to a map?

MartinNitschke

This has to be one of the easiest things there is, as there are no examples for it, except for the complex examples.  I am getting an error from the MapView.js about a "type" being null.   I am able to plot single points, but not more than one. I am able to see my data going into the Latitude and Longitude, but I must be missing something.

Martin,

   You are making the most common mistake that beginner JS developer make with Using the JS API and AMD style programming. Your requires and their subsequent vars have to be in the same order.

You have:

<SPAN class="token function">Require</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">[</SPAN>
&nbsp; <SPAN class="string token">"esri/views/MapView"</SPAN><SPAN class="punctuation token">,</SPAN>
&nbsp; <SPAN class="string token">"esri/WebMap"</SPAN><SPAN class="punctuation token">,</SPAN>
&nbsp; <SPAN class="string token">"esri/layers/FeatureLayer"</SPAN><SPAN class="punctuation token">,</SPAN>
&nbsp; <SPAN class="string token">"esri/Graphic"</SPAN><SPAN class="punctuation token">,</SPAN>
&nbsp; <SPAN class="string token">"esri/geometry/Point"</SPAN><SPAN class="punctuation token">,</SPAN>
&nbsp; <SPAN class="string token">"dojo/domReady!"</SPAN>
<SPAN class="punctuation token">]</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="keyword token">function</SPAN><SPAN class="punctuation token">(</SPAN>MapView<SPAN class="punctuation token">,</SPAN> WebMap<SPAN class="punctuation token">,</SPAN> FeatureLayer<SPAN class="punctuation token">,</SPAN> Point<SPAN class="punctuation token">,</SPAN> Graphic<SPAN class="punctuation token">)</SPAN> <SPAN class="punctuation token">{</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

You need:

<SPAN class="token function">Require</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">[</SPAN>
&nbsp; <SPAN class="string token">"esri/views/MapView"</SPAN><SPAN class="punctuation token">,</SPAN>
&nbsp; <SPAN class="string token">"esri/WebMap"</SPAN><SPAN class="punctuation token">,</SPAN>
&nbsp; <SPAN class="string token">"esri/layers/FeatureLayer"</SPAN><SPAN class="punctuation token">,</SPAN>
&nbsp; <SPAN class="string token">"esri/Graphic"</SPAN><SPAN class="punctuation token">,</SPAN>
&nbsp; <SPAN class="string token">"esri/geometry/Point"</SPAN><SPAN class="punctuation token">,</SPAN>
&nbsp; <SPAN class="string token">"dojo/domReady!"</SPAN>
<SPAN class="punctuation token">]</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="keyword token">function</SPAN><SPAN class="punctuation token">(</SPAN>MapView<SPAN class="punctuation token">,</SPAN> WebMap<SPAN class="punctuation token">,</SPAN> FeatureLayer<SPAN class="punctuation token">,</SPAN> Graphic<SPAN class="punctuation token">,</SPAN> Point<SPAN class="punctuation token">)</SPAN> <SPAN class="punctuation token">{</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

Notice above Graphic and Point now are in the same order as the preceding require modules.
