[jira] [Commented] (SOLR-7363) Expand component throws an Exception
when the results have been collapsed and grouped
[ https://issues.apache.org/jira/browse/SOLR-7363?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14485268#comment-14485268 ]
Brandon Chapman commented on SOLR-7363:
---------------------------------------
[~joel.bernstein], when collapsing was introduced, "traditional" grouping was explicitly supported. Is this just an oversight that expanding the collapsed result does not work if the result has also been grouped or is there a technical limitation?

> The expand component does not work when used on a result that has been both collapsed and grouped. This is counter-intuitive as collapsing and grouping work together with no issues.
