How to create a subscription to object events into a worklow ?

How to create a subscription to object events into a worklow ?

I would like to automatically create a subscription to object events inside a workflow, using java code.

looking into the windchill class documentation, I found that I should probably be using the following code :

wt.notify.NotificationHelper.manager.createObjectSubscription (wt.notify.NotificationSubscription, wt.notify.NotifySubscriptionRecipient, wt.notify.Notifiable, java.util.Hashmap<String, wt.fc.WTStringMap>, boolean)

but I found no explanation on how to get or build the parameters for this function.

I made some tries to create and initialise a wt.notify.NotificationSubscription object, a wt.notify.NotifySubscriptionRecipient object and a java.util.Hashmap<String, wt.fc.WTStringMap> object.

I used a cast on my primaryBusinessObject to get a wt.notify.Notifiable object.

But all without a lot of success.

Does somebody have a small working code example that would show how to use this createObjectSubscription function ?

Thanks in advance.

Following code works for 9.1 M40.

void constructSubscription(Notifiable targetObject) throws WTException, WTPropertyVetoException{

//Declare and initialize NotificationSubscription variable

NotificationSubscription subscriptionAttributes = new NotificationSubscription();

//set attributes for subscriptionAttributes

subscriptionAttributes.setName("My Custom Subscription Name");

subscriptionAttributes.setSubject("My Custom Subscription Subject");

subscriptionAttributes.setMessage("My Custom Subscription Message");

subscriptionAttributes.setSendImmediate(true);

//create Map for events. Events are case sensitive.

//Capitalize all characters and add "_" (underscore) between words

//Here is list of a few events

//CHECK_IN_FROM_PROJECT, CHECK_OUT_IN, COPY, DELETE,

//EDIT_ACCESS_CONTROL, EDIT_ATTRIBUTES, EDIT_IDENTITY, MARKUP,

HashMap<String,WTStringMap> eventsMap = new HashMap<String,WTStringMap>();

eventsMap.put("CHECK_OUT_IN", (WTStringMap)null);

eventsMap.put("DELETE", (WTStringMap)null);

//get subscriber, currently setting to session user

NotifySubscriptionRecipient subscriber = NotifySubscriptionRecipient.newNotifySubscriptionRecipient(SessionHelper.getPrincipal(), NotifySubscriptionRecipient.TO_ADDRESS);

//create subscription

NotificationHelper.manager.createObjectSubscription(subscriptionAttributes,subscriber, targetObject, eventsMap, true);

}

}

Thanks for the code.

It is not so far from what I tried, but it brings some information I missed.

I saw from your code that I do not need to build a WTStringMap for the event map

eventsMap.put("CHECK_OUT_IN", (WTStringMap)null);

That's a good point because I did not know how to do it.

I saw also that I should use a factory function to build a NotifySubscriptionRecipient, instead of calling "new".

However, when trying this new code in a workflow robot, I got the same error as before.

The root error seems to be an SQLException saying that a "LONG value can only be bound to a column of type LONG" and causing ROLLBACK exceptions.

Not very helpfull and not easy to relate to my code...

Anyway, thanks for your help.
