I have created an Arcade expression in ArcGIS Pro 2.3 to build the value for symbolization from to field.
I took the Arcade expression for unique symbol values:
I gave both fields field1 and field2 standard values and for each a domain in the field settings. Null is not allowed.
Every created symbol value gets a own symbol.
If I publish this layer as web layer the following problems occur:
I can change the values of field1 and field2 and as result the symbol changes in the edit mode.
The symbol in the edit widget in AGOL / Portal (10.7) in the Map Viewer or Edit Widget at WAB doesn't show a given symbol.
It shows only a small black dot.
I also tried to give a special symbol for all other values. This has the same effect.
How can I change that behavior?
Can I change the symbol at the edit widget with python api like Earl Medina showed?
Thanks for your help,
