Hello, I just realised that there is no implementation for the custom 
adapters,
So I make it work by implement my custom OutputServer that returns my 
Custom Adapter in case of custom adapter type selection.
Thanks, everything works fine

Dear Tali, 
I need some help with the development of a Custom Output Adapter, I 
managed to develop it but I want to know the process of repackaging in a 
war file and run it on the server.
so I need to recreate somehow the ProtonAgents.jar and put it back to the 
.war file? and if yes is there any online information on todo that?|
thanks in advance!

Dear Alex, 

Glad to hear you are using the CEP! 

What you can do: 
1. Have one EPA, lets call it EPA1, that uses the temporal context you 
defined, lets call it TC1, (initiator Event_X, terminated after 24 hours). 
Make EPA1 of type Aggregate, that uses TC1. Set the evaluation policy of 
EPA1 to be deferred and don't set it conditions or input event. Make it 
generate a new type of event (that you need to define), lets call it E2. 
The purpose of EPA1 is to generate E2 24 hours after Event_X arrives. (If 
you don't want to have a warning on empty input events you can put Event_X 
as an input event of EPA1) 

2. Now you can define another temporal context, lets call it TC2 that uses 
E2 as initiator. 

Hope this is what you wanted. 

I cc the FIWARE help, so this corresponding will be documented in the 
FIWARE issue tracking system. Please cc it as well in future 
correspondence. Thanks. 

Best regards,
Tali

Dear Tali,

I am a Software Engineer who collaborates with the FiWARE GE,
I am working on the IBM Proton about 2 weeks now, and I ma trying to 
configure a use case for the company I work for.  
I created a temporal context that starts the time that an Event_X is fired 
and it expires after 24hours, but I want a second temporal context start 
after 24hours of the event creation, can you please provide me some help 
on this? 
I tried to set the condition: Event_x.duration == 86400000, but that 
didn't work for me. 

Thanks in advance! 
Alex Zacharopoulos, Software Engineer @ Konnektid.
