Error "The evaluation of attribute rules is cyclic or exceeds maximum cascading level"

GeeteshSingh07

I am working on attribute rule. It is applied on two feature classes:
1. Main_FC
2. FC_Anno

The attribute rule on Main_FC is triggered on 'Update'. The rule is:

var globalId = $feature.GLOBALID;
var attach_anno = FeatureSetByName($datastore, "FC_Anno", ["FEATUREGLOBALID", "GLOBALID"], true);
var related_feature_anno = Filter(attach_anno, "FEATUREGLOBALID = @globalId");

if (related_feature_anno != null) {
    var updates = [];
    for (var f in related_feature_anno) {
        Push(updates, {
            'globalId': f.GLOBALID,
            'attributes': {
                'NAME': $feature.NAME
            }
        });
    }
    return {
        'edit': [{
            'className': 'FC_Anno',
            'updates': updates
        }]
    };
}

 

The attribute rule on FC_Anno is triggered on 'Insert & Update'. The rule is:

var fglobalId = $feature.FEATUREGLOBALID;
var main_fc = FeatureSetByName($datastore, "Main_FC", ["GLOBALID"], true);
var related_main_fc = Filter(main_fc, "GLOBALID = @fglobalId");

if (related_main_fc != null) {
    var updates = [];
    for (var f in related_main_fc) {
        Push(updates, {
            'globalId': f.GLOBALID,
            'attributes': {
                'NAME': $feature.NAME
            }
        });
    }
    return {
        'edit': [{
            'className': 'Main_FC',
            'updates': updates
        }]
    };
}

 

The attribute rule works fine if I disable any one of them. When both of them are enabled together, it gives an error: The evaluation of attribute rules is cyclic or exceeds maximum cascading level.

I looked into some of community discussions & solutions suggested by @HusseinNasser2 , and I understand when one feature is edited, it triggers the rule on the other class, which again edits the first class, triggering the rule again... and so on. This causes a cyclic dependency, which leads to the cascading evaluation error. However, I am still struggling to resolve this issue.

Any help on this will greatly be appreciated. Thank you.

You need to check if each row has the same name.    Try this:

var fglobalId = $feature.FEATUREGLOBALID;
var main_fc = FeatureSetByName($datastore, "Main_FC", ["GLOBALID", "NAME"], false);
var related_main_fc = Filter(main_fc, "GLOBALID = @fglobalId");

var updates = [];
for (var f in related_main_fc) {
    if ($feature.NAME == f.NAME){
      continue;
    }
    Push(updates, {
        'globalId': f.GLOBALID,
        'attributes': {
            'NAME': $feature.NAME
        }
    });
}
if (Count(updates) == 0 ){
    return
}
return {
    'edit': [{
        'className': 'Main_FC',
        'updates': updates
    }]
};

 

* Edited code, no reason to return Geometry and also needed to add NAME to the FeatureSetByName constructor
