I created an flow service HandleFB to implement the
wm.tn.rec:ReliableProcessingService specification. One action of a processing rule is to execute the HandleFB service as a service execution task. Everything seem works fine, like whenever my document was arrived in TN, the HandleFB
service was invoked, I got the result of the HandleFB service through email to prove the HandleFB service was working. But the TN Tasks view always show the invoke HandleFB service task failed and failed up to the maximum retry. There is no probable reason for failure logged in Activity Log for the first invoke action. While the subsequent retry Activity Log showed some errors like bizdoc input is null.
Is any one had experienced this problem before? Or is that some simple setting I missed?
