Hi,

I have a question about Subdialogs. I have two applications which one of them has subdialog invoke and another has subdialog start and subdialog return elements.

My question is; Do I have to send some session data to subdialog application as a parameter to use that session data in it? Can I read or write main application's session data from subdialog application without passing that session data to the subdialog as a parameter?

Thanks.

I thought so, but I couldn't be sure.

Thanks Janine.

Have you looked at the Element Specifications Reference Manual? It tells you how to use the Subdialog Invoke and where it stores the result returned from AppB; and it explains how to use the SubdialogReturn to return data back to AppA.
 
Basically, everything is passed as name=value pairs, and must be received by the other application by using that exact name.
 
So, to pass data back from AppB to AppA:  modify the SubdialogReturn in AppB by setting 'ReturnValue'  status={Data.Session.mystatus}
Then in AppA, mofidy the SubdialogInvoke by setting 'ReturnValue': status
 
In AppA, the ReturnValue's become element data for the SubdialogInvoke element. {Data.Element.SubdialogInvoke_01.status}

Don't use cvp subd return. Just use subd return

Hi Janine,
 
Thank you for your quick response.  I have followed the steps suggested by you.
But I still have the error and the activity log shows "Subdialog_Invoke,element,error,error.semantic"
 
I am passing 4 parameter from App-A to App-B through Subdialog Invoke element(See App-AtoApp-B.jpg)
I am able to get all the 4 parameters in App-B perfectly by setting the parameter names in Subdialog Start element. 
Now, I am returning a value from App-B through "CVP Subdialog Return" element (See ReturnValue.jpg)
       External VXML 0 is set as RET_TRANSCODE={Data.Session.TRANSCODE}
In App-A I am setting 'Return Value' in Subdialog Invoke element as "RET_TRANSCODE" (See App-AtoApp-B.jpg)
I am using the same name passed from App-B to App-A(i.e., RET_TRANSCODE), but I still have the error.
 
I have tried accessing the return value of App-A in a subdialog return in App-A as {Data.Element.Subdialog_Invoke.RET_TRANSCODE} (See App-A_SubdialogReturn.jpg)
 
Please let me know what went wrong.

Thank you,
Sreeram.

Hi,
 
I am using Sub-dialog Invoke element and I am able to transfer values from App-A to App-B and vice-versa.
But, when I tried to pass hashmap with 60-70 values, I am seeing the below message in my activity logs.
 
A session has timed out after 2 minutes. This is most likely caused by a start of call class or action element at the top of the callflow not completing before the voice browser's fetch timeout occurred. To resolve it ensure this class executes in a timely manner or run it in the background. Session timeouts may also occur under high load or if there are issues with a load balancer or voice browser.
 
I am also able to transfer a hashmap with few values(say 10-20) and from App-A to App-B.
 
I have also tried with multiple "session timeouts" like 1-minute, 5 minutes, 15 minutes and 30 minutes.
But still, I am not able to transfer the hashmap to App-B.
 
Please let me know, whether there is any restriction on the amount of data we pass from App-A to App-B.
 
 
Thanks,
Sreeram.

Ranjana,
Can you help us find out the limitation of size and number of parameters that can be passed in session data using Subdialog Invoke.
 
Thanks,
Sreeram
