Omit Fields without data from the Pop up Window on Online MapViewer

WFCAdmin

I recently reached out for help on this topic and @RhettZufelt and @gis_KIWI4 we very helpful in getting me going.

@gis_KIWI4provided me with the following arcade expression.

var attributes = Dictionary($feature)["attributes"];
var fieldInfos = [];
var attributeValues = {};


var excludeFields = ["OBJECTID", "EditDate"]; //Use this to exclude any fields, null or not null


var layer_schema = Schema($feature);
var fieldAliases = {};


for (var i = 0; i < Count(layer_schema.fields); i++) {
    var field = layer_schema.fields[i];
    fieldAliases[field.name] = field.alias;
}


for (var key in attributes) {
    var value = attributes[key];


    if (!IsEmpty(value) && value != "" && IndexOf(excludeFields, key) == -1) {
        var displayName = key; // Default to field name
        
        // Use alias if available
        if (HasKey(fieldAliases, key)) {
            displayName = fieldAliases[key];
        }
        
        Push(fieldInfos, { fieldName: key, label: displayName });
        attributeValues[key] = value;
    }
}



return {
    type: 'fields',
    fieldInfos: fieldInfos,
    attributes: attributeValues
};

 

This returns the pop-ups perfectly, with display names rather than field names.

My issue is, it only works on the first point I select. If I click on a second point, it won't pull up any pop-ups.

If I then click on another layer with a pop-up and then back on the filtered pop-up layer it works again. It's like it only works once and then needs something to reset it.

Any help troubleshooting this would be much appreciated!

I tried this modification, but made no difference.  Would still work as expected, once, then would only show system managed fields. 

However, playing around with it, I noticed that it will display the system managed fields AND any fields that are loaded elsewhere like the title or field list.

So, figured I'm make sure and 'load' all fields into the script and I tested both the original and modified script by adding:

Expects($feature, '*')    

as the first line.

Now it seems to be working as expected, and populates all non-empty fields (that aren't in the exclude list) each time I click on a feature.

It still re-orders them alphabetically though, have not figured that one out yet.......
