Test waits forever for a callback from a human task

Question

Hi,
I've create a test to test a BPEL process. Now within the BPEL process there is a call to a human task service. I've emulated the task initiation message which is fine. I also tried to emulate the receive message from the human task service but during the test execution, the test waits forever to receive the callback from the human task service, even though i've specified the return message. Would appreciate help with this! I've posted my testbpel.bpel and the test case (CreditCardInvalidTest.xml) below. For both these files I've highlighted in bold the relevant bits of code that's giving me problems. Thanks

Hi hi, on a hunch I previewed the page in the browser, and copy pasted the faces/untitled1 portion of the URL there and pasted on the http://<server_address>:8001/BasicAPPDemo_Root therefore ending with http://<server_address>:8001/BasicAPPDemo_Root/faces/untitled1 and lo and behold I saw the little text box saying "Hello World" ;D
So with that i escalated, switched to the application where the page from BPM was located, deployed it and did the same trick.
But it borked it gave this error:
JBO-29115 Unable to construct the error message due to error java.lang.NullPointerException. Use the exception stack trace and error code to investigate the root cause of this exception. Root cause error code is JBO-.
I figured that the Default generation could be faulty so i created a new page and only recycled the data controls, created everything in read mode, just to test and deployed, when i tested, i was optimistic as the 1st tab didn't had any error (also does not have anything related to the HumanTask, even the data controls) the problem was in the other tabs as I show here.
Many thanks sirs, and sorry for wasting thy time.
