<div class="jive-rendered-content"><p>Hi,</p><p>I am using the JBPM 5.1 Final version which is released recently for one of the customer which is supposed to goLive very soon.</p><p>I hve few important things which is difficult to handle,</p><p>1. org.jbpm.DemoTaskService - loads all the users and the groups present in the LoadUsers.mvel and LoadGroups.mvel in the TaskServiceSession. </p><p>     1.1. Practically this is going to be huge performance hit incase of even small size organization with 100 - 150 user/groups.  </p><p>     1.2. Is there any way / flag by which the user details of only that particular user is loaded who is accessing the server? </p><p>     1.3 Why it needs to load all the users/groups in the session?</p><p>      1.4 It is currently loads .mvel file to load users/groups? Is there any other version of this class which accees DB?</p><p>      1.5 When i comment loading of users and groups and try to start a process, it gives following error in the jboss-5.1.0.GA\server\default\log\server.log. It creates the process instance but task is not created.</p><p>   </p><table><tbody><tr><td style=";">2011-06-25 20:34:24,351 INFO  [STDOUT] (http-localhost%2F127.0.0.1-8080-1) ERROR 25-06
