Hi, i've been integrating an application with the jbpm console; and i've jumped the step of login and home pages until to the task.jsp, for the users from my application go directly to task.jsp.
i've used code from UserBean.java for the login():
| UserBean userBean = new UserBean();
| userBean.setUserName("edison acosta");
| session.setAttribute("userBean",userBean);
|
| userBean.login();
|
and code from HomeBean.java for to load an task instance(selectTaskInstance()) if exists the process, or to load a process(startProcessInstance) if is the first time that the user starts the process.
also i use code from a script that produces home.jsp
| <form id="linkDummyForm" name="linkDummyForm" style="display:inline" method="post" action="/jbpm/faces/task.jsp">
|
| <input type="hidden" name="linkDummyForm:_link_hidden_"/>
| <input type="hidden" name="taskInstanceId"/>
| <input type="hidden" name="processDefinitionId"/>
|
|
| <script type="text/javascript">
|
| function clear_linkDummyForm() {
|
| var f = document.forms['linkDummyForm'];
| f.elements['linkDummyForm:_link_hidden_'].value='';
| f.elements['taskInstanceId'].value='';
| f.elements['processDefinitionId'].value='';
| f.target='';
|
| document.forms['linkDummyForm'].elements['linkDummyForm:_link_hidden_'].value='_id14_0:_id17';
| document.forms['linkDummyForm'].elements['processDefinitionId'].value='1';
|
| if(document.forms['linkDummyForm'].onsubmit){
| document.forms['linkDummyForm'].onsubmit();
| }
| document.forms['linkDummyForm'].submit();
| return false;
| }
| clear_linkDummyForm();
|
| </script>
| </form>
|
my problem is when i try to submitt the "Save and Close" button, then throws an exception:
