How to programatically create connector tags?

[danm]

Hi,
  There's a bug in EA that connector tags are ignored if they are created from a template (via the usual Tag{name="" value=""} syntax). Darn, OK I hope this will get fixed soon. In the meantime I've been trying to find a way to do it via an add in, but I can't find any method. Only query methods, no set methods. Any ideas?

Code: [Select]


       public object EXEC_connectorAddTag(EA.Repository repository, object argsObject)
       {
           string[] args = (string[])argsObject;
           string connectorGUID = args[0];
           string tagName = args[1];
           string tagValue = args[2];
           object aTag;

           EA.Connector connector = repository.GetConnectorByGuid(connectorGUID);
           
           aTag = connector.TaggedValues.AddNew(tagName,tagValue);
           connector.TaggedValues.Refresh();
           connector.Update();
   
           return "";
       }


This code doesn't work. I can't continue until I can add a tag to a connector but nothing works ....

aTag.Update()

Thanks - tried that, but aTag doesn't contain ".Update()" because it's an object. I tried casting it to various types, EA.TaggedValue for instance, but those raise a com exception. brrrrrr

Awesome! That worked.

Last problem - the tags are being applied to the OLD connector, not the new transformed connector. I'm using as my GUID connectorGUID which is the old one as it turns out (I thought the same GUID would be used for both.) Do you have any tips on how to get a handle to the transformed GUID, from within the transformation?

Thanks!!!!!!!

Awesome! That worked.  

 Sorry, but what worked?  Can you post the full line of code for the update?

Thanks

Code: [Select]


public object EXEC_connectorAddTag(EA.Repository repository, object argsObject) {
           string[] args = (string[])argsObject;
           string connectorGUID = args[0];
           string tagName = args[1];
           string tagValue = args[2];
           EA.ConnectorTag aTag;

           EA.Connector connector = repository.GetConnectorByGuid(connectorGUID);
           EA.ConnectorEnd clientEnd = connector.ClientEnd;
         
           aTag = (EA.ConnectorTag) connector.TaggedValues.AddNew(tagName,tagValue);
           aTag.Update();

           connector.TaggedValues.Refresh();
           connector.Update();
           return "";
}


This function takes a connector GUID and a tag name and value, and creates the tag on the connector. Presently as far as I can tell, EA ignores all attempts to create connector tags from within a transformation, so you need to do it via an add-in.

The final Refresh() and Update() are probably unnecessary.
