I am new to the workflows and i am trying to do a simple private message workflow.  The start task takes a name and a message.  The problem is setting the data.  When I iterate through the task variables I get this very weird problem:

here it the model:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<type name="jiswf:privateMessage">
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<parent>bpm:startTask</parent>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<properties>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<property name="jiswf:toName">
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<type>d:text</type>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<mandatory>true</mandatory>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<multiple>false</multiple>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</property>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<property name="jiswf:privateMessage">
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<type>d:text</type>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<mandatory>true</mandatory>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<multiple>false</multiple>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</property>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</properties>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</type>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

it is launched by a java web script:

      WorkflowDefinition wfDefinition = workflowService.getDefinitionByName("activiti$privateMessageProcess");
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Map<QName, Serializable> vars = new HashMap<QName, Serializable>();
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; vars.put(QName.createQName(AlfrescoModel.WORKFLOW_NAMESPACE,"toName"),toName);
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; vars.put(QName.createQName(AlfrescoModel.WORKFLOW_NAMESPACE,"privateMessage"),message);
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;workflowService.startWorkflow(wfDefinition.getId(), vars);
‍‍‍‍‍‍‍

and a simple iterator through the variables in the task listener (Java):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Map<String,Object> vars = task.getVariables();
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Iterator<String> keys = vars.keySet().iterator();
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;while(keys.hasNext()) {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;String key = keys.next();
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;System.out.println("Key:"+key+" Value:"+vars.get(key));
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}
‍‍‍‍‍‍‍‍

The output is the issue:

  Key:jiswf_toName Value:joe
  Key:jiswf:privateMessage Value:asdfasdf
‍‍‍‍

Why oh why is one key "jiswf_toName" and the other "jiswfrivateMessage"

that difference between "_" and ":" makes it hard to get the variables out of the model as you can imagine. Using v4.2.d comm.

Any help is appreciated.

Under normal circumstances,when you put qname varaiable into workflow varaiable ,alfresco will convert qname to bpm varaiable (replace : {} to _ ,for example convert jiswf:toName to jiswf_toName).
So technically all varaiables  can be retrieved using underline format.
