Не работает NOT_EQUAL с пустой строкой (bmp 7.4)

var select = Ext.create("Terrasoft.EntitySchemaQuery", { rootSchemaName: "Equipment1C" });
select.isDistinct = true;
select.addColumn("OwnerCode1C");
select.addColumn("OwnerName");
select.addColumn("Account");
select.addColumn("AccountOrganizationChart");
select.addColumn("Contact");

var emptyStr = "";
select.filters.add("ownerCode1CFilter", Terrasoft.createColumnFilterWithParameter(Terrasoft.ComparisonType.NOT_EQUAL, "OwnerCode1C", emptyStr, Terrasoft.DataValueType.TEXT));

var emptyStr = "00057";
select.filters.add("ownerCode1CFilter", Terrasoft.createColumnFilterWithParameter(Terrasoft.ComparisonType.NOT_EQUAL, "OwnerCode1C", emptyStr, Terrasoft.DataValueType.TEXT));
