Portal 10.6.1 chyba nebo Arcade Syntax Error?

Provozuji Portal for ArcGIS 10.6.1 a snažím se použít Arcade Attribute Expression k vyplnění pop-up okna. Zde je moje syntaxe:<\/P>

Syntaxe je správná při testování:

Ale nemohu ji zobrazit v samotném pop-up okně. Zkoušel jsem použít Zobrazení podle "A description from one field" a vybrat výraz ze seznamu; také jsem zkoušel "A custom attribute display" s odkazem na výraz. Ani jednou se věta z části Value testu výše nezobrazila v pop-up okně. Když se vrátím do nastavení pop-upu, možnosti jsou resetovány na "A description from one field", ale můj výraz je stále uložen v sekci Attribute Expressions.

Myslel jsem si, že by to mohla být chyba verze 10.6.1 a našel jsem a nainstaloval patch ArcGIS-1061-PFA-SEC2019U1-Patch, ale problém to nevyřešilo. Také jsem zkusil stejný výraz v ArcGIS Online a výsledek byl stejný.

Možná Decode není podporováno pro pop-upy ve verzi 10.6.1? Kontroloval jsem version matrix, ale nejsem si jistý, zda tabulku čtu správně.

Hi  Amy Roust ,

The easiest way would be to leave the decode out and test with a dummy text to see if the Decode is the reason for the expression not to work. A way to leave out Decode is using dictionaries like this:
