Simbología de ArcGIS Online / Portal con Arcade

Question

Hola:

Me parece impresionante poder usar el nuevo lenguaje Arcade para la simbología o el etiquetado en ArcGIS Online / Portal.

Ahora tenemos el siguiente problema:

Si creo una simbología que depende de 2 campos y los concateno en un solo valor para la simbología con Arcade, ¡la simbología desaparece del mapa y de la plantilla de entidades, y solo se muestra un punto negro!

Nuestro servicio de entidades tiene su propia plantilla de entidades basada en los campos concatenados, pero al editar, ¿no se muestran los símbolos (marcadores) creados?

¿Alguien tiene alguna idea de por qué ocurre esto?

Saludos,

Karsten

Hi Karsten Rank ,

Not sure if I understand your question correctly, but if you want to publish a layer that has a dynamic calculation inside of it, you might want to look at attribute rules. With calculation attribute rules you can have a trigger that the creation of a new feature starts the calculation of a field based on other fields automatically.

I want to create a symbology depending on two field on the flow.. E.g. if you have five different layers with 20 different symbols, the editor widget is overloaded with 100 symbols.

So my idea was to show only a standard symbol and by changing the attributes, the symbol should change.

Is it possible to publish a field calculation with ArcGIS Pro to a Portal feature service?

Hi Karsten Rank ,

What I think is happening is that there is no support for the edit templates to be based on a "virtual field" created with an Arcade expression. I can imagine that you would like to select a concatenated value and that this would fill the two fields it is based. Is that what you want to achieve?

You can use the field calculation and create a actual field for the concatenated values (for which you could define a domain with the accepted values) and create two expressions to extract both parts from this field. That would work.
