Subject

I’ve enable orm entity audit following docs but when I try to compare revisions it shows only the entity without the compared entity and highlighted fields.

Digging into why I’ve found that it’s no possible to extend a block provided from a macro. Look at this issue at Stackoverflow.

CRUDController:historyCompareRevisionsAction renders SonataAdminBundle:CRUD:base_show_compare.html that extends SonataAdminBundle:CRUD:base_show.html.twig and this imports macro SonataAdminBundle:CRUD:base_show_macro.html.twig with blocks show_field and show_title thats base_show_compare try to override but nothing happens. So compare action only shows the entity.

To test this I’ve pasted code from base_show_macro into base_show making necessary adjusts and compare action works great, highlighting with read modified fields.

I hope I made the flow clear.

Steps to reproduce

Enable audit and try to compare revisions. It will show only the entity without compared entity.

Expected results

Show 2 entities and highlighted fields.

Actual results

Show only the revision.
