Looks like the first Upper() needs a parameter;
possible fixes could be:
generated filter field is broken (i'm using the default for the specific column)
FilteringTable needs to call an explicit query for foreign key columns (I tried to find where I could do this to no avail)

The error happens as soon as one character is typed in the offending filter box,
the JpaContainer.size() call runs the broken query, from what I saw stepping through the debugger

Is there a way to specifically set a Foreign Key filter?

My generated column is generated so:
filterTable.addGeneratedColumn(columnName, new CustomTable.ColumnGenerator() { static final long serialVersionUID = 1L; @Override public Object generateCell(CustomTable source, final Object itemId, Object columnId) { EntityItem<Device> rowItem = deviceContainer.getItem(itemId); TimingGroup group = rowItem.getEntity().getGroup(); return group.getName(); } });
group is also the name of the JPA Entity field containing the said group.
