Setting up a treshold filter with the UI, it did not work because the unit field was blank. I got an NPE from PersistenceTresholdFilter, and the PersistenceIncludeFilter would also throw a NPE in that case. For PersistenceTimeFilter, defaulting to "s" is just cosmetic. Picks-up PR #3681 and should be merged for the 4.0 release, because the UI does not prevent the unit field from being null. Signed-off-by: Florian Hotze <[email protected]>
