Hi,
Hi!
i got a strange issue with the table grid. Sometimes i get the
message: 'There is no data to display.'
This will happen if the source parameter provides zero objects to be
shown.
I know, but only the grid source is null. The database has datas.
To make it more clear:
@Log
void setupRender() {
List<Tachyon> produkte =
entityManager.createNamedQuery("Tachyon.findAllByStatusTrue").getResultList();
System.out.println("Count Products: " + produkte.size());
}

As you can see, the table has 'Count Products: 406' rows, but there is
no call of getTachyonenprodukte.
That is the issue, sometimes the method is called sometimes not.
