Problem understanding event parameters

[Mark Pyc]

G'day Karen,
 
The event parameters allow you to pass additional information that cannot be
determined within the object attributes. If it were possible to access it
within the object there would be no need to specifically pass it with the
event. Workflow does not use genuine OO and all attributes must be able to
be resolved at runtime based only on the key to the object.
 
Once you've bound your data and hold it within your workflow container
however, you can pass it to the object via a call to a method. Alternatively
since you're coding the raise of the event and passing the parameter,
potentially you could pass the email address directly.
 
Hope this helps,
Mark

Subject: Problem understanding event parameters
 
 
Dear workflowers:
 
Here's what I'm trying to do, but it's not working.
 
>From a program I put an element in a container, then create an event.
 
    code:
    swc_set_element <event container> 'USERID'  var_userid.
    call function 'SWE_EVENT_CREATE'
          .
          .
          .
 
The event being created has the parameter USERID.
 
I also put USERID in the workflow container and put it in the binding
between the event and the workflow, therefore I know a value is in the
parameter.
 
My problem is:
 
I want to use the USERID parameter to create an attribute in the object.
This object contains the event that is triggering the workflow.
 
In the coding for the attribute, the first thing I do is:
 
    swc_get_element container 'USERID' usrid.
 
I get nothing in the variable usrid.  Do I have access to the event
parameters at the time the object is being created?  If so, how can I access
it?
If not, can somebody tell me where to put the code that converts the userid
to an email address that is needed in a task within the workflow?
 
Thanks for any help you can give.
