Generated Mappers causing cyclic method call when upgrading from v7.7.0 to v7.8.1

[tejaswibm-roposo]

Overview of the issue

I had generated JHipster - React app with v7.7.0. Now, I have upgraded it to v7.8.1 based on the documentation here by running npx jhipster upgrade command.

This re-generated the mapper classes from JPA to DTO.

The generated mapper classes in v7.8.1 are different from those generated with version v7.7.0 and there is a cyclic method calls getting generated which were not present in v7.7.0.

Motivation for or Use Case

Due to cyclic method calls, SO error is getting thrown from the server.

Reproduce the error

Generate entities as given in the jdl below.

Related issues

Suggest a Fix

Not Sure. Maybe revert mapper generator to the same as provided in v7.7.0

@tejaswibm-roposo Can you confirm this is related with the same issue from https://github.com/jhipster/generator-jhipster/issues/18729?

[tejaswibm-roposo]

@DanielFran - I doubt its the same issue. The issue here is the way the mapperImpl are getting generated whose behaviour has changed from v7.7.0 to v7.8.1. Attaching snippets for an entity generated using the schema mentioned in the bug in both versions -

1. v7.8.1

package com.inmobi.glance.brolly.service.mapper;

import com.inmobi.glance.brolly.domain.Post;
import com.inmobi.glance.brolly.service.dto.PostDTO;

@Mapper(componentModel = "spring", uses = { AzUserMapper.class, PostAttributeMapper.class, CommentMapper.class })
public interface PostMapper extends EntityMapper<PostDTO, Post> {
    @Mapping(target = "azUser", source = "azUser")
    @Mapping(target = "postAttributes", source = "postAttributes")
    @Mapping(target = "comments", source = "comments")
    PostDTO toDto(Post s);

    @Named("id")
    @BeanMapping(ignoreByDefault = true)
    @Mapping(target = "id", source = "id")
    PostDTO toDtoId(Post post);

I have upgraded JHipster already. Hence, not able to get earlier version of generated mapperImpl. Question - Why is 1-n mapping of entity not being mapped in dto and mapperImpl. Ex: PostAttributes and Comments set ? In v7.7.0, this was handled as expected.

This issue is stale because it has been open for too long without any activity. Due to the moving nature of jhipster generated application, bugs can become invalid. If this issue still applies please comment otherwise it will be closed in 7 days

JHipster has completed the sample check .yo-rc.json: valid Entities JDL: error Application: Frontend check: skipped Backend check: skipped E2E check: skipped

This check uses jhipster info output from the issue description to generate the sample. Bug report that does not contain this information will be marked as invalid.

Sample is missing information, cannot be reproduced. Fixes for cyclic relationships landed in https://github.com/jhipster/generator-jhipster/pull/24746. Closing.
