SUP HWC: Data is not flowing from Listview --> "Listview Details Screen"

Hi All,

I am doing a HWC application.

In that I have 2 screens "My_Requests" and "Request_Details".

To show "My_Reuqests" I am using Listview UI element.

In "Request_Details" (Listview Details Screen) I am calling custom action to get the total details of the request.

(NOTE: I am calling custom action method in customAfterShowScreen )

out of 100 times 5 times data is not flowing to "Request_Details" screen

We are not able to reproduce the scenario also.

Please find the attached workflow log file and word document with screen shots

(word document download link: http://www.ziddu.com/download/21618430/ListviewDetailscreenissue.docx.html)

In logfile below statement is showing empty request no, while calling  custom action menuItemCallbackRequest_DetailsGetDetails();

Please help me to resolve the issue.

Thanks in advance,
