WSO2 BPS foreach问题

Question

I am trying to do a forEach , and inside forEach use the counters in a doXSLTransform to derive the source. It is working fine if the forEach finalCounter = 1 otherwise i am getting error for passing multiple elements in the doXSLTransform source. I checked the Oasis specs for BPEL and it supports passing the counter using the $ , please advise as I am not sure what is going wrong with WSO2 BPS.

Answer 1

Did you try with round function. Usually, it resolves the problem.

$output.payload// [local-name()='activity'][round($counter1)]/ [local-name()='dp'][round($cou‌​nter2)]

Answer 2

我反复尝试了一下，它适用于do变换，但不适用于Assign xpath表达式，这确实很奇怪。
