How to retrieve associations of a content type

Good day,I am trying to retrieve known associations off a type that is attached to a node using javascript. I have tried several ways that seems not to work, or perhaps I just do not know. Here is the script I am running in attempt of achieving this.<javascript>var originalUser = people.getPer

I have heard of Alvex but I have not looked at its content model. Are you sure that alvexoc:delegation is a *child* association and not a *peer* association? If it is a peer association, use assocs instead of childAssocs.

Hello.

Delegations are stored in childAssocs, but content model for them is quite tricky to support 'delegation by role' in addition to 'default delegation'. See slide 17 in http://www.slideshare.net/itdsystems/orgchart-for-alfresco-lightning-talk for details.

There are two options to achieve what you want. The first one:
<javascript>
var originalUser = people.getPerson("user1");
var delegateeUserName;

if(originalUser.hasAspect("alvexocrgchartMember"))
{
   if(originalUser.properties["alvexocutOfOffice"] == true)
   {
      var delegation = originalUser.childAssocs["alvexoc:delegation"][0];
      delegateeUserName = delegation.assocs["alvexoc:delegationTarget"][0].properties.userName;
      logger.log(" %%% " + delegateeUserName);
   }
   else
   {
      logger.log(delegatee + " *******$$$$$$$$*******");
   }
}
else
{
   logger.log("Person is in the office ********************");
}
</javascript>

However, I'd prefer the second option and use native Alvex root-scope object:
<javascript>
// We use orgchart.getPerson() here instead of people.getPerson()
var originalUser = orgchart.getPerson("user1");

if(originalUser.getOutOfOffice())
{
var delegateeUser = originalUser.getDefaultDelegation().getTarget();
logger.log( "Out of office, delegated to: " + delegateeUser.getUserName() );
}
else
{
logger.log( "In office" );
}
</javascript>

This method is better not only because it's shorter. The point is that we (as Alvex development team) will provide API-level backward compatibility, but we can not guarantee that backend models will stay the same in the future Alvex releases.

The only thing to note about native 'orgchart' root scope object - call to orgchart.getPerson() returns JscriptOrgchartPerson object. You can take a look at https://github.com/ITDSystems/alvex/blob/master/core/orgchart/repo/src/java/com/alvexcore/repo/orgchart/jscript/JscriptOrgchartPerson.java for methods available.

Hi avasyukov.

You solution worked like a charm. As you might have guessed, I had tried all other avenues I knew or thought of to no good; one of the attempts was very close to your solution, just lacked something.

I am very grateful for your assistance. However, option 2 does not seem to work.

Many thanks.
