Trigger with count and regular expression not working

[mwildam]

Hi folks, I have a trigger like this:

{DB:db.checkprocesses["{$DBNAME}","{$DBAGENTPROCESSES}","{$DBUSER}"].count(#30,"CRIT.*")}>=1

where the db.checkprocesses is UserParameter running a shell script returning a text that may start with OK, WARN or CRIT (it's a script I have taken from an older Nagios configuration).
As in this case the dingy process I am checking (parameter $DBAGENTPROCESSES passed to the item) is often absent for a while but then returning, I only want to fire an event, if the script returns CRIT for a longer period of time or for the last n data requests. When I test this trigger it does not fire at all (re-load of configuration cache done several times), although I have at least 3 CRIT messages there in the history within the last 30 values.
So I really have no clue why that is not firing. Any ideas? Here is my data:

OK, I found the problem myself - I was missing the "regex" in the operator:

{DB:db.checkprocesses["{$DBNAME}","{$DBAGENTPROCESSES}","{$DBUSER}"].count(#30,"CRIT.*",regex)}>=1
