[SOLVED] Working with bpm_groupAssignees in Activiti workflow

[cnfwriter]

I see a few, sparse examples of working with bpm_groupAssignees (note the plural - not groupAssignee) in jBPM only.

How does one get at the members from groupAssignees from an activiti workflow?

I imagine one would loop through the groups and individually do a getGroup on each group contained in bpm_groupAssignees.

I'm stuck on exactly how to get at groupAssignees from javascript in an activiti workflow.

Any help appreciated!

bpm_groupAssignees will be available as variable and should be an array. You should be able to do something like:

<javascript>
for(var i=0; i< bpm_groupAssignees.length; i++){
var group = groups.getGroup(bpm_Assignees );
}
</javascript>

If you see errors where your loop doesn't seem to be firing, try:


<javascript>
for(var i=0; i< bpm_groupAssignees.size(); i++){
var group = groups.getGroup(bpm_Assignees.get(i) );
}
</javascript>

Hopefully that helps. If you need more direction, provide more context on what you're trying to accomplish and I can elaborate.

Thanks Max,

It did help to know that bpm_groupAssignees is merely an array.

What I want to do is allow a user to choose 1..N groups for a workflow instead of a single group.

Maybe I'm assuming too much, but I can't seem to run normal javascript functions inside ScriptTaskListener. Does it only allow a certain subset of javascript?

For example, if I try to use a simple 'for' loop as in your example, loading the workflow fails outright while starting Alfresco.

This simple task fails . . .

            <activiti:taskListener event="create" class="org.alfresco.repo.workflow.activiti.tasklistener.ScriptTaskListener">
               <activiti:field name="script">
                  <activiti:string>
                     var x=10;
                     for (var i=0; i < x; i++) {
                        logger.log( "Number of loops: " + i );
                     }
                     
                  </activiti:string>
               </activiti:field>
            </activiti:taskListener>

Looks like you're using the activiti script listener. logger is a root object provided by alfresco. If you're using the designer, try dragging out an alfresco script task and choosing alfresco script from the radio options.

I still seem unable to get at the actual groups in bpm_groupAssignees.

I want to loop through the groups, then pull the members of each group into an array.

Every method I've tried seems to say that 'group' is null.

groups.getGroup(bpm_groupAssignees doesn't seem to yield anything either.

Do I need to do something like – var group = groups.getGroup(bpm_groupAssignees.properties["cm:authorityName"]; ???? (which doesn't actually work either)

NOTE: logger is where I will have the array; I'm just trying to see if I can print the members for now.

for(var i=0; i < bpm_groupAssignees.size(); i++){
     var group = groups.getGroup(bpm_groupAssignees.get(i) );
     var members = people.getMembers(group);
                     
     for(var x in members) {
          logger.log("Member is: " + members[x].properties.userName);
     }               
}

bpm_groupAssignees might return the group scriptnode, try something like

bpm_groupAssignees.properties.name
bpm_groupAssignees.properties.authorityName

I can't remember exactly where the shortname is stored.

Yeah, that was it Max. I got it now. Thanks!!

logger.log( "Size is: " + bpm_groupAssignees.size() );            
                   
for(var i=0; i < bpm_groupAssignees.size(); i++){                  
   var members = people.getMembers( bpm_groupAssignees.get(i) );
                     
   logger.log( "Groups are: " + bpm_groupAssignees.get(i).properties["cm:name"] );
                     
   for(var i in members) 
   {
     memberNames.add(members.properties.userName);
     logger.log( "Members are: " + members.properties.userName );
   }
}
