Label expression doesnt work

EvelynHernandez — Mon, 03 Dec 2018 20:54:50 GMT

Hello everyone,

Im having a problem with a label expression in ArcMap that we have setted up.

As u can see, we added a label exp in VScript that works in Arcmap but when we go to the mapview that we made, the layer is showing the datetime in another way (not with the logic we put it the expression).

What could be happening?

Thanks in advice.

Are you accessing that layer through a MapImageLayer or is it just coming from the web map?

Evelyn,

So you are adding this layer as a ArcGISDynamicMapServiceLayer? Do the labels appear properly when you just view the map using the REST end point

Yes i am.

In arcmap (after the configuration for the label) it is showing in the map like in the pic 1. (Thats what we want)

But after we go to our web app (adding it as ArcGISDynamicMapServiceLayer) the label is showing a different thing (pic 2)

Do the labels appear properly when you just view the map using the REST end point by clicking on the:

Evelyn,

Then the map service is not capable of displaying the complex label expression. It has nothing to do with the Javascript API. When you published this service did you not get some warning about this?

Uhm no, we didnt see any

I would contact tech support. I believe that it is just a label expression limitation of a map service that you are encountering.
