There is a property on the TimeoutControl Node which has little literature about and is confusing me a little

its;

Quote:
Count - Default 1 - Set this element to an integer value that is either greater than 0 or is -1 (which specifies a timeout request that never expires). The default value is 1.


No my understanding is i send a contrl message to the timeoutControl via an input queue that sets my unique identifier etc and a timeout period

Code:
            
DECLARE expiryTime TIME;
SET expiryTime = CURRENT_TIME + CAST(timeoutSeconds AS INTERVAL SECOND);
-- Set the clock ticking...
SET OutputRoot.XMLNSC.TimeoutRequest.Action = 'SET';
SET OutputRoot.XMLNSC.TimeoutRequest.Identifier = 'EXCD_INVNTRY';
SET OutputRoot.XMLNSC.TimeoutRequest.StartTime = expiryTime;
SET OutputRoot.XMLNSC.TimeoutRequest.Count = 1;
SET OutputRoot.XMLNSC.TimeoutRequest.IgnoreMissed = TRUE;
SET OutputRoot.XMLNSC.TimeoutRequest.AllowOverwrite = TRUE;
PROPAGATE TO TERMINAL 'out1';   


and that all works fine and places a message on the SYSTEM.BROKER.TIMEOUT.QUEUE

The expiryTime is set to some 7200 seconds = 2 hours so it will set a message to a TimoutNotification Node in the same flow in 2 hours - all this is fine BUT I also set the AllowOverwrite to TRUE which means I should be able to change that "whole" SET setting for that UID right?
So I do I change the expiry time to now be 90 seconds based on some event but get an exception saying the UID is already covered (thought that was the idea of the overwrite) but when I send a cnacel later it removes all as expected - BUG? or Misunderstanding??

Also what is the count option for? - there is limited literature - i understand the -1 is unlimited but is this the expiry time on the SYSTEM.BROKER.TIMEOUT.QUEUE
before the message expires then and is it in what minutes seconds millenia??

Thx

What is the exact exception you are seeing? I would have expected for AllowOverwite to behave like you are expecting it to.

Regarding 'Count' and 'Interval' - When your TimeoutNotification event starts, it will propagate {Count} messages every {Interval} seconds. So as as example, if I want my flow to be invoked 20 times, as 13:00:00 with a delay of 5 seconds between the invocations I would have:
StartTime = 13:00:00
Count = 20
Interval = 5

This is the way I have understood it.

Thanks for the reply and was my understanding also on the count front si I have it set to count 1 (i.e do once) and no interval as its not repetitive but the exception I get for the overwrite is

Recoverable Exception

Code:
RecoverableException
   File:CHARACTER:F:\build\S610_P\src\DataFlowEngine\TimeoutControl\ImbTimeoutControlNode.cpp
   Line:INTEGER:965
   Function:CHARACTER:ImbTimeoutControlNode::evaluate
   Type:CHARACTER:ComIbmTimeoutControlNode
   Name:CHARACTER:IF205_TimeoutHandler#FCMComposite_1_5
   Label:CHARACTER:IF205_TimeoutHandler.TimeoutControl_EXCD_INVNTRY
   Catalog:CHARACTER:BIPv610
   Severity:INTEGER:3
   Number:INTEGER:4610
   Text:CHARACTER:Timeout Set Identifier already used
   Insert
         Type:INTEGER:5
         Text:CHARACTER:EXCD_INVNTRY
