Getting Null pointer exception on overriding assistedServiceService in hybris

After overriding OOB assistedServiceService I am getting NPE in OOB class DefaultAssistedServiceFacade.java for line assistedServiceService.getAsmSession()

To override service I have followed below steps.

1- Declared bean in customextension-core-spring.xml file as below

<alias name="defaultcustomAssistedServiceService" alias="assistedServiceService"/>
<bean id="defaultcustomAssistedServiceService" class="com.custom.core.services.impl.DefaultCustomAssistedServiceService" parent ="defaultAssistedServiceService"><br>        <property name="flexibleSearchService" ref="flexibleSearchService"/>
</bean>

2- Created a custom class overriding OOB defaultCustomAssistedServiceService class

public class DefaultCustomAssistedServiceService extends DefaultAssistedServiceService implements CustomAssistedServiceService {
private FlexibleSearchService flexibleSearchService;

@Override
public CartModel getCartByCode(final String cartCode) {
}

public FlexibleSearchService getFlexibleSearchService() {
    return flexibleSearchService;
}

public void setFlexibleSearchService(FlexibleSearchService flexibleSearchService) {
    this.flexibleSearchService = flexibleSearchService;
}

Since Object of assistedServiceService is already been used in other OOB classes, So wherever its been called it is giving NPE. Am I missing something in service overriding?

Please note OOB assistedServiceService is defined in OOB extension 'assistedServiceService' in file assistedserviceservices-spring.xml as

 <alias name="defaultAssistedServiceService" alias="assistedServiceService"/>
<bean id="defaultAssistedServiceService" class="de.hybris.platform.assistedserviceservices.impl.DefaultAssistedServiceService">
    <property name="modelService" ref="modelService"/>
    <property name="userService" ref="userService"/>
    <property name="baseSiteService" ref="baseSiteService"/>
    <property name="cartService" ref="cartService"/>
    <property name="sessionService" ref="sessionService"/>
    <property name="flexibleSearchService" ref="flexibleSearchService"/>
    <property name="pagedFlexibleSearchService" ref="pagedFlexibleSearchService"/>
    <property name="commerceCartService" ref="commerceCartService"/>
    <property name="customerAccountService" ref="customerAccountService"/>
    <property name="commonI18NService" ref="commonI18NService"/>
    <property name="timeService" ref="timeService"/>
</bean>

Below is stacktrace which I am getting

Solution

  • fixed the error by calling super method in facade, where I was setting the object of service.

    public void setAssistedServiceService(CustomAssistedServiceService assistedServiceService) {
    super.setAssistedServiceService(assistedServiceService);
    this.assistedServiceService = assistedServiceService;
}
