Question

How can I add a loading mask to the [Connected to] detail of the [Accounts] section (version 7.7.0) in a diagram display mode?

Answer

To add a loading mask to the [Connected to] detail of the [Accounts] section in a diagram display mode, create a replacing client module for the AccountRelationshipDetailV2 schema and insert the following code therein:

define("AccountRelationshipDetailV2", [], function() {
    return {
        methods: {
            loadRelationship: function() {
                this.set("MaskId", Terrasoft.Mask.show({
                    selector: "#RelationshipTabContainer"
                }));
                this.callParent(arguments);
            },
 
            relationshipDiagramServiceCallback: function(response) {
                this.callParent(arguments);
                Terrasoft.Mask.hide(this.get("MaskId"));
            }
        },
 
        diff: /**SCHEMA_DIFF*/ []/**SCHEMA_DIFF*/
    };
});

Save the schema and reload the application page with clearing the cache.
