    Thank you for your reply.<br>
    <br>
    Yes sure I have that. I took the rules directly from <a
href="http://javabeans.asia/articles/drools_5_case_study_2_complex_event_processing.html"><br>
http://javabeans.asia/articles/drools_5_case_study_2_complex_event_processing.html</a><br>
    and they include this setting.<br>
    <br>
    <br>
    As posted in my fist mail I needed to change 90d in following code
    to 90m to get the tutorial to work.<br>
    &nbsp;&nbsp;&nbsp; from accumulate(<br>
    &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; ClaimApprovedEvent(<br>
    &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; accountNumber == $account.number, <br>
    &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; $amount : amount<br>
    &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; ) <br>
    &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; over window:time( 90d ) from <br>
    &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; entry-point ClaimStream, <br>
    &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; average($amount)<br>
    &nbsp;&nbsp;&nbsp; )<br>
    <br>
    <br>
    I can use 's', 'm' or 'h' only with 'd' I get an error marker in
    eclipse:<br>
    Description&nbsp;&nbsp;&nbsp; Resource&nbsp;&nbsp;&nbsp; Path&nbsp;&nbsp;&nbsp; Location&nbsp;&nbsp;&nbsp; Type<br>
    Error: java.lang.NullPointerException&nbsp;&nbsp;&nbsp; account.drl&nbsp;&nbsp;&nbsp;
    /SlidingWindowCEP/etc&nbsp;&nbsp;&nbsp; Unknown&nbsp;&nbsp;&nbsp; Drools Error<br>
    <br>
    <br>
    btw.: The tutorial seems to use some discouraged Classes so I have
    quite a few warnings <br>
    about PackageBuilderConfiguration, MVELDialectConfiguration and
    SessionPseudoClock <br>
    however I have the same issues with this as written here:<br>

    It seems to me I must have some basic setting wrong but I have yet
    to figure out what it is,<br>
    so hints are still very much appreciated.<br>
    <br>
    <br>
    Best regards,<br>

          head on this for hours and then<br>
          just after I write you I get a step further. I changed mvl
          mode and replaced<br>
          line 78 in Tester.java with:<br>
          PackageBuilderConfiguration conf = new
          PackageBuilderConfiguration();<br>
          &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;((MVELDialectConfiguration)<br>

          <br>
          Now the markers are still being displayed but the code
          compiles and runs. If<br>
          someone would take the time to explain this to me I'd be very
          thankful.<br>
