How to load table with criteria?

[harifenny]

Hi there,
I want load table with criteria, so I modify my BaseArAp.ts like this

`
namespace wCore.HRMS {
export class BaseArApGrid extends Common.GridEditor<BaseArApRow, any> {
protected getColumnsKey() { return 'HRMS.BaseArAp'; }
protected getDialogType() { return BaseArApDialog; }
protected getIdProperty() { return BaseArApRow.idProperty; }
protected getLocalTextPrefix() { return BaseArApRow.localTextPrefix; }
protected getService() { return BaseArApService.baseUrl; }

    protected getDeletePermission() { return BaseArApRow.deletePermission; }
    protected getInsertPermission() { return BaseArApRow.insertPermission; }
    protected getReadPermission() { return BaseArApRow.readPermission; }
    protected getUpdatePermission() { return BaseArApRow.updatePermission; }
    protected getExportPermission() { return 'HRMS:BaseArAp:Export'; }

    constructor(container: JQuery) {
        super(container);
    }

    protected onViewSubmit() {
        if (!super.onViewSubmit()) {
            return false;
        }

        var request = this.view.params as Serenity.ListRequest;

        request.Criteria = Serenity.Criteria.and(request.Criteria,
            [['IsReceivable'], '=', true])
            ;

        return true;
    }

}

}`

But, if I run this project, I got an error like this

IsReceivable is a boolean/bit and I want to load
IsReceivable == true only

How to fix it?

Thanks & Regards,
