That's what I'm looking for. Thank you.

For other users looking for this. Here is my actual log4j config:

Logger


<logger name="ch.ivyteam.ivy.richdialog.exec.internal.panel" additivity="false">
            <level value="debug"/>
            <appender-ref ref="FileLog2"/> 
 </logger>

Appender


   <appender name="FileLog2" class="org.apache.log4j.DailyRollingFileAppender"> 
       <param name="File" value="Y:/Temp_ToRemove/ch.ivyteam.ivy.broadcast.log"/> 
       <param name="DatePattern" value="'.'yyyy-MM-dd"/> 
       <layout class="org.apache.log4j.IvyLog4jLayout"> 
          <param name="DateFormat" value="HH:mm:ss.SSS"/>
       </layout> 
    <filter class="org.apache.log4j.varia.StringMatchFilter">
        <param name="StringToMatch" value="Scheduling fire event" />
        <param name="AcceptOnMatch" value="true" />
    </filter>
    <filter class="org.apache.log4j.varia.DenyAllFilter" /> 
  </appender>

There is a logger which logs on DEBUG when a event gets prepared to be fired on the class ch.ivyteam.ivy.richdialog.exec.internal.panel.RichDialogPanelImpl. The message is like Scheduling 'fire event' <{0}> with attachment <{1}> (from panel <{2}>)

I can't say if this log output will help to find the corresponding event source. Maybe a own log-output will give clearer results.

Thank you for your answer.

We do not open one task parallel two times. We open different Tasks (Task A and Task B). After they are both open the user for example press a Button and in the Dialog procces logic the Broadcast event will be fired. Both Tasks catches the event. The data in the Broadcastevent will be written to our Database for both Tasks. So, one of the Tasks is now linked to wrong data.

We allready got a solution to solve the problem. But we don't know which Broadcast in the solution causes the Problem. Therefore my Question how get information about which Broadcast was fired when, for which tasks?

kind regards Thomas

Hello Thomas Wirz. Technically it is not possible to start the same task parallel. So, which data do you mean. Data in a Database? However, a possible solution could be to add a flag on the broadcasting event (e.g. 'handled'). Handlers do their work only if the flag is false. The first handler sets the flag to true so that all others do not process its logic.
