This is always returning []. Am i missing something?
List<Jazdy> jazdy = <<<there is some Jazdy.class list>>>;
List<Jazdy> jazdicky = dataManager.load(Jazdy.class)
.query("select j from doprava_Jazdy j where j in :jazdy")
.parameter("jazdy",jazdy)
.view("jazdy-view")
.list();
Your code and JPQL statement seems correct and should work. You could set eclipselink.sql logger to DEBUG to see executed SQL queries in app.log using Administration > Server log screen, or edit logback.xml and restart Tomcat (Documentation). It may help to understand what goes wrong.
