Using tHashOutput and tHashInput in Talend esb - esb

Question

I am trying to merge two responses using tHashOutput -> tHashInput, so firstly I am trying to use it for simple, straightforward job and it doesn't work. I send via Soap UI request with ID, then based on this ID retrive name from DB and show it as result. Data are inserted into hashOutput, but aren't there in hashInput.

Answer from Shong from Talend Team on official forum:
Hi
I think this is because 'keep listening' box is checked on tESBRequestProvider, tHashInput linked with onsubjobOK will never work. To resolve it, change the job design to:
tESBRequestProvider.....tHashOutput--oncomponentok-tHashInput--main--tESBResponseProvider
