Event
The Event tab has the following fields.
Field |
Description |
Candidate Event Key |
Expression built from the data of the incoming message. This expression should evaluate to a string and it is compared to the "key" field of the activity’s input. If the Candidate Event Key and the activity’s key match, then the process accepts the incoming message. For example, you may have a Publish to Adapter activity that sends a message with a particular ID. You are expecting a reply message that contains that same ID so that you can determine the message is a response to your sent message. You would specify the field of the incoming message that contains your ID in the Candidate Event Key. You would then use the message ID of the message you sent earlier in the process as the "key" field in the input. This expression is specified in XPath, and only data from the incoming event is available for use in this XPath expression. For more information about XPath expressions, see TIBCO ActiveMatrix BusinessWorks™ Process Design. |
Event Timeout (msec) |
A message may arrive before this activity is executed. This field specifies the amount of time (in milliseconds) a message waits if it is received before this activity is executed. If the event timeout expires, an error is logged and the event is discarded. If no value is specified in this field, the message waits indefinitely. If zero is specified, the event is discarded immediately, unless this activity has already been reached. |
