Script Automation - add asynchronous signal to sequence diagram

[tweber]

Does anyone know how to configure a connector on a sequence diagram so it shows as an asynchronous signal, rather than as a synchronous call?

[Geert Bellekens]

Make two connectors, one synchronous, and one asynchronous, and then compare both records in t_connector to figure out the difference.

Thanks for the quick reply.  I've done that.  The async info is stored in PDATA (1 and 3).  That said, MiscData(0) and MiscData(2) are read only and I can't update them to 'Asynchronous' and 'Signal' respectively.  I'm searching for a way to create a signal via script.

Thanks.

You need to place an according UPDATE SQL in repository.execute("..."). It's undocumented but the only circumvention we have in such cases.

Hello tweber,

You can use Connector.Properties collection. In this collection, when Property.Name = "Kind", set Property.Value = "Signal" and similart to "IsAsync".

HTH,

Takeshi K,

I added this to my script:
  evConn.Properties("Kind").Value   = "Signal";
  evConn.Properties("IsAsync").Value   = true;

That worked. 

For connectors,
Properties contains five (key, value) pairs:

Looks like my reply got truncated.

The five Key, Value pairs are:
Name    Value = the name of the message/signal
Type      Value = "Sequence"   (apparently, for both message and signal)
Kind      Value =  <blank> for Message, "Signal" for signals
IsReturn Value = boolean
IsAsync  Value = boolean (true for signals)

Appreciate your help.
