Bhaskaran Venkataraman [https://community.jboss.org/people/bhaskarven] created the discussion "jbpm5-example-for-forms-with-variables" To view the discussion, visit: https://community.jboss.org/message/737449#737449 -------------------------------------------------------------- I am trying to understand the example discussed in the following blog. Excellent example to explain the concepts. https://community.jboss.org/people/bpmn2user/blog/2011/02/21/jbpm5-exampl... https://community.jboss.org/people/bpmn2user/blog/2011/02/21/jbpm5-exampl... I have a few questions related to that. 1. What is the purpose of the "Preprocess" script task ?     From the example it looks like it creates a map object and sets default values for modelNumber, quantity and priority. The map      object that contains these parameters are mapped to map process variable by the code :     kcontext.setVariable("map", map);     The content parameter is set to map in the human task "Sample Order Task" as shown below in the properties window     Parameter Mapping                    {content=map}     When the user is going to input values in the human task form why is there a need to preset variables in the     "Preprocess" script task ?( which are anyway going to be overwritten by the human task "Sample Order Task" )      My understanding is that we only need result mapping to transfer the values entered by the user back      to process variables.     Am I missing something here ? 2. There are 2 ftl forms in the zip file "ProcessOrder.ftl" and "SampleApprovalTask.ftl" which I understand are related to the human tasks      "Sample Order Task" and "Sample Approval Task". There is a third one "com.sample.bpmn.sampleHTformvariables.ftl" and also its image      com.sample.bpmn.sampleHTformvariables.png. I did not understand the context for these 2 files ? 3. I believe the driver ( Java Program ) that came for the sample Evaluation application should work for this application also. Am I right ? Your response will be greatly appreciated. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/737449#737449] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
