History Plugin

The HistoryPlugin generates a workflow history for each process instance depending on the configuration in the workflow model.


For each workflow step the HistoryPlugin generates a separate entry which is added into the history list (txtworkflowhistory) of the WorkItem. Each history entry provides the following entries:

  • date of creation (Date)
  • comment (String)
  • userID (String)

The number of entries for the history list can be restricted to a maximum number of entries by adding the attribute “numworkflowhistoryLength” into the workitem. The Attribute indicates the maximum number of entries. If lower 0 no limit is set.

The History entries can be configured in the workflow model using the Imixs-BPMN Modeler. The following example shows how to output the workflow history list using facelets:

<ui:fragment rendered="#{!empty workflowController.workitem.item['txtworkflowhistory']}">
    <h:dataTable var="log"
         <h:outputText value="#{log[0]}">
          <f:convertDateTime timeZone="#{message.timeZone}" type="both"
              pattern="#{message.dateTimePattern}" /> 
         <h:outputText value="#{log[1]}" />
