Question

I am entering values(URLs) in the text box and when I click the next button, validation runs whether the entered url values are valid or not.

if the urls are not valid then i display the error as below

if(valid == false){
this.errors.reject("Incorrect URL is entered for  "+countries.get(countryCode)+" - please ensure to use a correct URL for More Games.")
return [];
                }

Once the error is shown, its clearing the entered values and need to enter the values again. How can I restrict clearing the values(i think the page is getting loaded again) or to restrict the page to load again.

here is the command –

class DeliveryMoreGamesURLCommand implements Command {
    private static final LOG = LogFactory.getLog(DeliveryController.class)

    def wrapperService = ApplicationHolder.application.getMainContext().getBean("wrapperService");
    def customerService = ApplicationHolder.application.getMainContext().getBean("customerService");
    def countryService = ApplicationHolder.application.getMainContext().getBean("countryService");
    def helperService = ApplicationHolder.application.getMainContext().getBean("helperService");
    def ascService = ApplicationHolder.application.getMainContext().getBean("ascService");

    Hashtable<String, String> countries;

    public LinkedHashMap<String, Object> preProcess(sessionObject, params, request) {
        Delivery delivery = (Delivery) sessionObject;

        def customer = Customer.get(delivery.customerId);
        def contentProvider = ContentProvider.get(delivery.contentProviderId);
        def deployment = Deployment.get(delivery.deploymentId);
        def operatingSystem = OperatingSystem.get(delivery.operatingSystemId);

        countries = wrapperService.getCountries(deployment, operatingSystem);
        def sortedCountries = countries.sort { a, b -> a.value <=> b.value };

        def urls =  ascService.getMoreGamesUrlsPerTemplates(deployment, operatingSystem);

        def moreGamesUrls = new Hashtable<String,String>();
        countries.each { country ->
            String countryCode = countryService.getTwoLetterCountryAbbreviation(country.key);
            String url = customerService.getMoreGamesUrl(customer, contentProvider, countryCode);
            if ("".equals(url)) {
                url = urls.get(country.key);
                if (url == null) {
                    url = "";
                }
            }
            moreGamesUrls.put(country.key, url); // We need to use the existing country code if the channels are deployed with three letter country codes
        }

        return [command: this, countries: sortedCountries, moreGamesUrls: moreGamesUrls]
    }

    public LinkedHashMap<String, Object> postProcess(sessionObject, params, request) {
        Delivery delivery = (Delivery) sessionObject;

        def urls = params.gamesUrls;
        LOG.debug("urls from gsp :"+urls)
        try{
        urls.eachWithIndex { u, i ->
            String countryCode = u.key;
            String url = urls["${u.key}"]
            if(url != ""){
            Boolean valid = helperService.isURLValid(url)
                if(valid == false){
                   this.errors.reject("Incorrect URL is entered for "+countries.get(countryCode)+" - please ensure to use a correct URL for More Games.")
                   return [];
                }
            }
        }
        }catch (Exception ex) {
                    logger.warn("Incorrect URL is entered", ex)
                    return [];
        }

        def moreGamesUrls = new Hashtable<String, String>();
        urls.eachWithIndex { u, i ->
            String countryCode = u.key;
            String url = urls["${u.key}"]
            moreGamesUrls.put(countryCode, url);
        }

        delivery.countries = countries;
        delivery.moreGamesUrls = moreGamesUrls;
        LOG.debug("moreGamesUrls after edit=${delivery.moreGamesUrls}");

        return null;
    }
}

from the command preprocess the data will be rendered and after clicking the next button, the postprocess will be invoked and the validation for the url…

Resolved this issue by implementing moreGamesUrls as a global variable(which stored the values even after the error is thrown)
