I have a "starter" ccxml application that loads a different ccxml application depending on some situation. I am trying to pass the session object via the fetchparam attribute, and various other variables via the namelist attribute. The code looks like the following:

<createccxml next="'outgoing.ccxml'" fetchparam="'session'" namelist="param1 param2 param3" />

In the logs for the outgoing.ccxml application, I can see when the ccxml application is loaded, the information passed via the "queryArgs" parameters, but I have no idea how to access this information:

Example

queryArgs: [
param1: "192.168.1.188"
param2: "true"
param3: "Test"
__AVAYA_FETCH_PARAM_TYPE: "session"
__VPapploggingurl: "https://10.10.2.20/axis/services/VPReport4"
__VPapplog: "/axis2/services/VPAppLogService"
__VPvpms: "10.10.2.20"
__VPappvars: "/axis2/services/VPAppVarsService"
__VPVarAppDate: "0"
__VPVarAppURL: "https://10.10.2.20/axis/services/VPAppRuntimeVars"
__VPVarGlobalDate: "1265733203015"
__VPbreadcrumb: "disabled"
__VPmaxbackuplogfiles: "10"
__VPlogname: "%default%Ba0FgR0EhNdjIYci"
__VPlogpassword: "v/ywfDJZk4xD23bGUYVg6yvIqjSQEkTOQeZEKurxcDbHCMWzLPYNx5Cr5mQ5IEqu"
__VPappname: "Michael Test"
]

As you can see, param1, param2 and param3 are listed with the correct values. Additionally, the __AVAYA_FETCH_PARAM_TYPE is indicative of "session".

1) How do I access the values of param1, param2 and param3? I have tried "session.values.param1", "session.values.avaya.param1", "session.values['param1']", "session.param1" to no avail. :(

2) How do I access the session information that was passed using the <createccxml fetchparam... /> call?

I just tried this both in simulation and on the platform and it worked for me per the CCXML specification. Please use the CreateSession example application to test this.

         <var name="paramparameters" expr="'parametersvalue'" />
         <createccxml
            next="'<%=locationLocal%>/ccxml/child.jsp?x=a'"
            method="'post'"
            namelist="paramnamelist"
            parameters="paramparameters"
            fetchparam="'session'"
            sessionid="childId" />


Then in the child ccxml I dump out the session object and see:

values.mpp.vpms_net_addr:acb70.sv.avaya.com
values.paramparameters:parametersvalue
ioprocessors.basichttp:https://148.147.10.89:10443/mpp/ccxml/basichttp.php

Once I changed "namelist" to "parameters", I'm able to access the parameters via the session.values.___ variables. Thank you, Ross. :)

One of the things I'm trying to do with passing the session object as the fetchparam is to be able to play a dialog on the incoming connection. How do I accomplish this? Every time I try to access the parent session connection id, I get an error that the connection doesn't exist... :(

Thanks again,
Michael

namelist always goes the the where the page is fetched (start dialog, create session) and parameters are sent to the new instance (Dialog or ccxml session).

In the child you cannot access connections in the parent. The way it would work is that you would use "move" to move the connection from one session to another.

"<move> is used to move an event source (such as a Connection object) to an executing CCXML session. When an event source is moved to a session, events originating from that source MUST be delivered to that session's currently executing CCXML document. Support for the <move> element is optional in CCXML platforms. Even if <move> is supported platforms MAY only support it between a restricted set of CCXML sessions. If <move> is unsupported the CCXML platform MUST raise an error.move event."

In EP move is unsupported.

In the child session you can create new connectoins (createcall) and send events between the parent and child session.

Any way to accept an incoming call in the child session? Or join a parent connection into a conference in a child session?

The child cannot accept the connection. But I am not sure if you passed the connection id to the child and then joined the conference created in the child if that would work or not. I know the participants on a conference must be one the same MPP. I would try it out and see.
