CTI Link Event Errors

SA-58762

Summary



Jtapi Rule-Service-Java instances defined in Pega-CTI:07-31-01 cause Java compile errors which blocks CTI implementation. When linking to Avaya, the user is able to send login and logout commands, however, cannot receive events from the CTI server.

On logging in to the the application, error related to the CTILinkEvent services occur. On resaving the service rules to the application ruleset and changing the Event Data parameter to EventData, the error does not occur. However, processing of the event does not complete.

Steps to Reproduce



Log in with Pega Call with an agent ID extension and password.


Root Cause



The parameter name was modified from Event Data to EventData in CTILinkEvent Java services

With the service class set to ApplicationGateway, the QueryRequest Rule-Service-Java caused the error. 
With the service class set to Jtapi, all Java services that used this parameter displayed the error. This occurs even though the parameter was not passed to the service activity.



Resolution



Apply HFix-44209.
