    Description

      We got the master item returning values in the following way:

      6.509
      4
      8.178
      

      And 3 dependent items based on it by Regular expression:

      (.*)\n(.*)\n(.*)
      

      \1, \2 and \3 respectively. We also have a trigger with the following problem expression:

      {Template01:step.responsetime.1st["{HOST.NAME}/{#STEP_NAME}"].last()}>{#THR_RESPONSETIME} and
      {Template01:step.responsetime.2nd["{HOST.NAME}/{#STEP_NAME}"].last()}>{#THR_RESPONSETIME} and
      {Template01:step.responsetime.3rd["{HOST.NAME}/{#STEP_NAME}"].last()}>{#THR_RESPONSETIME}
      

      where {#THR_RESPONSETIME} is being resolved into 5.5

      At some moment N we got the following values from these dependent items: 6.509, 4, 8.178.
      The trigger instantly went in a problem state though 2 out of 3 values did not satisfy the condition.

      Please find trigger expression test result which shows condition shouldn't be met.
      Please let me know if you need any addition information on the issue.

      Thank you
