[infinispan-issues] [JBoss JIRA] (ISPN-5682) The minimum aggregation function doesn't work with Strings

[Adrian Nistor (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-5682?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13103858#comment-13103858 ] 

Adrian Nistor commented on ISPN-5682:
-------------------------------------

Minimum aggregation does work with Strings, see the QueryDslConditionsTest.testMin/testGlobalMin. 

The problem here seems to be different, more related to projections on properties of embedded entities rather than the type of the property.
