Link back query not working for ContentBlocksFieldPlugin

I am new to hippo cms so apologies if i am not using correct terminologies.

I have followed this link and got the first query working cms hippo docs

I have got 2 doctypes Master and Servant respectively.

Master doctype java and yaml file are as follows

@HippoEssentialsGenerated(internalName = "website:link")
public List<HippoBean> getLink() {
    return getLinkedBeans("website:link", HippoBean.class);
}

yaml code

  /link:
    /cluster.options:
      base.path: /content/documents
      jcr:primaryType: frontend:pluginconfig
      last.visited.enabled: true
      nodetypes:
      - website:servant
    caption: Link
    field: link
    hint: ''
    jcr:primaryType: frontend:plugin
    plugin.class: org.hippoecm.frontend.editor.plugins.field.NodeFieldPlugin
    wicket.id: ${cluster.id}.field

  /link:
    hipposysedit:mandatory: false
    hipposysedit:multiple: true
    hipposysedit:ordered: false
    hipposysedit:path: website:link
    hipposysedit:primary: false
    hipposysedit:type: hippo:mirror
    hipposysedit:validators:
    - optional
    jcr:primaryType: hipposysedit:field

Master has got linkedbean to link to servant doctype as shown above.

Now in the Servant doctype i would like to show the master details, so i added a query as shown below and it works as expected.

public Master getParentDetails() {
    final HstRequestContext context = RequestContextProvider.get();

    try {
        HstQuery linkedBeanQuery = ContentBeanUtils.createIncomingBeansQuery(
            this.getCanonicalBean(), context.getSiteContentBaseBean(),
            "*/website:link/@hippo:docbase",
            Master.class, false);
        linkedBeanQuery.setLimit(1);
        return (Master) linkedBeanQuery.execute().getHippoBeans().nextHippoBean();
    } catch (QueryException queryException) {
        log.warn("QueryException ", queryException);
    }
    return null;
}

The problem is when i change the plugin class in Master to plugin.class: org.onehippo.forge.contentblocks.ContentBlocksFieldPlugin and add compound list compoundList: website:junior things stop working and give error.

Note that now the getlink() method and the link yaml code shown above is moved into a new compound called junior.

Master is just for allowing multiple compounds of junior with appropriate code as shown below.

@HippoEssentialsGenerated(internalName = "website:servantlink");
public List<HippoBean> getServantlink() {
    return getLinkedBeans("website:servantlink", HippoBean.class);
}

yaml code

  /servantlink:
    /cluster.options:
      jcr:primaryType: frontend:pluginconfig
      nodetypes:
      - website:servant
    caption: groups
    compoundList: website:junior
    contentPickerType: links
    field: servantlink
    hint: ''
    jcr:primaryType: frontend:plugin
    plugin.class: org.onehippo.forge.contentblocks.ContentBlocksFieldPlugin
    wicket.id: ${cluster.id}.field
    wicket.skin: skin/content-blocks.css
  /servantlink:
    hipposysedit:mandatory: false
    hipposysedit:multiple: true
    hipposysedit:ordered: false
    hipposysedit:path: website:servantlink
    hipposysedit:type: hippo:compound
    hipposysedit:validators:
    - contentblocks-validator
    jcr:primaryType: hipposysedit:fiel

So my question is how the query should be now?

Any help would be highly appreciated. Thanks in advance

So finally got it working

The master java class should be as follows. Please note use getChildBeansByName instead of getLinkedBeans here.

@HippoEssentialsGenerated(internalName = "website:servantlink");
public List<HippoBean> getServantlink() {
    return getChildBeansByName("website:servantlink");
}

No changes in the master.yaml its all good. Now the query part in Servant java class should be as follows.

    final HstRequestContext context = RequestContextProvider.get();

    try {
        HstQuery linkedBeanQuery = ContentBeanUtils.createIncomingBeansQuery(
            this.getCanonicalBean(), context.getSiteContentBaseBean(),
            "website:servantlink/website:link/@hippo:docbase",
            Master.class, false);
        linkedBeanQuery.setLimit(1);
        return (Master) linkedBeanQuery.execute().getHippoBeans().nextHippoBean();
    } catch (QueryException queryException) {
        log.warn("QueryException ", queryException);
    }
    return null;
}

The most important part is this website:servantlink/website:link/@hippo:docbase.
