Eu tenho uma expressão de atributo usada em um popup que é exibido em um mapa web ArcGIS, mas não em um aplicativo web ou no collector. var relatedData = FeatureSetByName ( $datastore , "RelatedData" ) var filteredRelatedData = Filter ( relatedData , Concatenate ( "id=" , $feature . id ) ) var orderedFilteredRelatedData = OrderBy ( filteredRelatedData , 'date DESC' ) var newest = First ( orderedFilteredRelatedData ) if ( IsEmpty ( ) ) { "n/a" } { Já aceitei o fato de que isso não funciona no ArcGIS Collector. E agora parece que isso também não está funcionando em um aplicativo web. Isso é realmente frustrante. No entanto, estou procurando uma página web ou documento que liste as limitações do Arcade em todos os produtos ESRI. Alguma ideia de onde posso encontrar algo assim? PS. Eu sei que a expressão Arcade acima não é performática.

nav[aria-label="Primary Navigation"] { padding: 0; & ul { list-style: none; width: 100%; display: flex; flex-direction: row; justify-content: start; align-items: start; gap: 30px; padding: 0; & li { margin: 0; } & ul li { list-style: none; } } }

Procurando uma fonte que liste as limitações do Arcade em todos os produtos?

The ArcGIS Arcade version matrix page on at the ArcGIS for Developers website states which Esri products support which version of ArcGIS Arcade. ArcGIS Online is not on the list but it should always support the latest version of ArcGIS Arcade.

Version Matrix | ArcGIS for Developers

On the ArcGIS Arcade function reference page when you click on a function it will tell you at what version of ArcGIS Arcade the function was introduced.

Arcade Function Reference | ArcGIS for Developers

It would be nice if the function reference page would just let you filter functions by version number to make it easier to see what you have to work with.

I hope this helps.

Thank you Michael. It works as well with a simple count in a web map but not in Collector or a web app.

Thank you Joshua Young‌, that helps already a lot!

It answers my question.

I found the following source but my understanding is that the web app we use runs with ArcGIS JS 3.29 aka newest version:

https://developers.arcgis.com/arcade/guide/faq/#why-doesnt-my-expression-work-in-my-web-app-but-it-does-in-arcgis-online

I have analyzed the source code of the web (map) app by using a developer console. It seems to be ArcGIS JS 3.29. Therefore, Arcade 1.7 should be supported according to the matrix. But it's actually not... or I miss something.

ArcGIS JS 3.29

Hi moosetraveller ,

You mention "MapApp Builder", are you referring to the Web AppBuilder (WAB)? Where are you seeing the blank fields? In Collector (using iOS or Android?) or in the web app?

Thomas_Z1

Hi Xander Bakker‌,

Thank you very much but the script works great on ArcGIS Online in a web map, returns no error in the configuration window and values are correctly shown in the popups. (I modified and anonymized this script for this forum.)

The problem is, that when creating a map app using MapApp Builder, the expression is not evaluated and blank fields are shown.

Hi moosetraveller ,

What error are you seeing when you test the Arcade expression in the configuration window?

I would probably make some minor adjustments:

Are you sure that the data is related like this and not through an GlobalID? Because that would make the the query different. Also you can include some Console statements to see where the code fails.

Have you tried Arcade on other types of fields such as text or numeric fields? Maybe there is a limitation at this time with date/time fields.
