Hi,
I have a simple workflow that calls a child workflow using a IPC event.
I want pass 1 field from parent workflow to child, and when child workflow ends, I want return data to parent workflow.
In the IPC event wizard I created a field mapping entry and I chose "Send data to child process" from data direction DropDownlist and I created other one and I chose "Receive data from child process" .
When I call the child workflow, I can pass data to child, but when the child finish, it didn't pass any data to parent.
I need to do something to pass data from child to parent workflow?
Thanks in advance
IPC not return data

+11Are you are calling the IPC synchronously? If the mode is async then the parent does not wait for the child to complete.
+2Yes, I was calling synchronously. The parent workflow only advances after child process ended, but didn't return data.
+2I tried a new thing. I set all the mapped fields to "Send and Receive" and set initial value to all fields. After the IPC all the parent workflow fields were empty.
After this, I saw data audit in the K2 Log DB, and all the fields were empty in a activity called "IPC Finish".
Any Clue why this happens?
Thanks
+11If you think it is a bug, open a help desk ticket. I have used the IPC event in the past to do just what you are describing. If you want, send me a very simple workflow project that illustrates this behavior and I will see if I can reproduce it. Unfortunately my schedule is filled for the rest of the week, so I make no promises about when I will be able to look at it.
