@Condition applied on wrong source parameter while mapping #4037

Expected behavior

@Condition method should be correctly applied on correct source parameters when we are using nullValueCheckStrategy = NullValueCheckStrategy.ALWAYS

Actual behavior

When we have the mapping mapping with 2 source parameters, for eg:

@Mapping(target = "browserId", source = "requestBean.deviceInfo.browserId")
public abstract AudienceProfileRequest map(RequestBean requestBean, String slotId);

If we are mapping some Integer source field from RequestBean to AudienceProfileRequest then the condition is applied on slotId which is not expected. Following is the snippet of the generated code:

Integer browserId = requestBeanDeviceInfoBrowserId( requestBean );
if ( prechecksSupport.isNotBlank( slotId ) ) {
    audienceProfileRequest.browserId( browserId );
}
