Title: Notification When an Element is Modified
Post by: SteveC on September 11, 2018, 07:32:14 am

Is anyone aware of how an add-in can be notified when an element is modified?

For example, I'd like to know when the user changes a tagged value of one of the elements. This would allow the add-in to check if it should perform any processing on the element based on the new tagged values.

There's a hook (EAOnContextItemChanges IIRC out of memory). But it does not report TV changes.

I had this requirement sometime ago and used EA_OnNotifyContextItemModified but this doesn't let you know if this is due to a tagged value change. 

Hence, my approach was to use EA_OnContextItemChanged to track the selection of an element, and take a copy of tagged values before any changes.  Then when ContextItemModified is triggered a check can be made to see if there is any difference for a tagged value.  Not ideal..

There is a (fairly) new set of events related to editing tagged values:

Unfortunately, they are only relevant for AddinBroadcast (http://www.sparxsystems.com/enterprise_architect_user_guide/14.0/modeling_tools/predefinedtaggedvaluetypes.html) tagged values.

But you could use them to force tagged value edits to go through your addin.

Ahh, too bad   :'(

Would be nice to have such a general "taggedValueModified" event thoug.
