Issue with Role-Based Lookup Filtering in Editable Detail Grid

Hi Creatio Community,

I'm currently working with an editable detail grid, and I need to filter a lookup column (UsrPort) based on the connected user's roles ("Stay SPOC TC", "Stay SPOC Casablanca", "Stay SPOC Jorf Lasfar", "Stay SPOC Laayoune", and "Stay SPOC Safi").

I've tried several approaches including:

• Defining lookupListConfig with prepareList binding (works fine on regular pages but does not trigger in editable grids).

  
  
  Here's the latest implementation I've tested:
   

generateActiveRowControlsConfig: function(id, columnsConfig, rowConfig) {
    this.mixins.ConfigurationGridUtilitiesV2.generateActiveRowControlsConfig.call(this, id, columnsConfig, rowConfig);
 
    var scope = this;
 
    Terrasoft.each(rowConfig, function(columnItem) {
        var columnKey = columnItem.key && columnItem.key[0];
        if (columnKey && columnKey.name === "UsrPort") {
            columnItem.controlConfig = columnItem.controlConfig || {};
            columnItem.controlConfig.lookupListConfig = columnItem.controlConfig.lookupListConfig || {};
            columnItem.controlConfig.lookupListConfig.filter = function() {
                var filters = Terrasoft.createFilterGroup();
 
                // Example of role checks
                var allowedPorts = [];
                if (scope.get("IsStaySpocCasa")) allowedPorts.push("CASABLANCA");
                if (scope.get("IsStaySpocJorf")) allowedPorts.push("JORF LASFAR");
                // Add similar checks for other roles
 
                if (allowedPorts.length > 0) {
                    filters.add("PortFilter", Terrasoft.createColumnInFilterWithParameters("Name", allowedPorts));
                } else {
                    filters.add("EmptyFilter", Terrasoft.createColumnFilterWithParameter(
                        Terrasoft.ComparisonType.EQUAL, "Id", Terrasoft.GUID_EMPTY));
                }
 
                return filters;
            };
        }
    }, this);
},

This configuration currently doesn't work and results in the error mentioned above.

Could someone help clarify the correct way to implement role-based filtering on lookup columns within editable detail grids? If anyone has successfully implemented this or faced a similar issue, your guidance would be greatly appreciated!

Thanks in advance for your help!

Best regards,
