Extension Tool is not working for Outgoing Response - Transport Header
I am extracting the Header from output Transport Header by using Header Databank.
context.getValue("Generated Data Source", "HeaderDatabankColumnName")
I want to refer same in output Response - Transport Header Extension tool. But seems it's not working.
As per my debugging I could not even print test message using Application.showMessage("Test Message") while referring java Extension tool from Outgoing transport Header -> Extension Tool. While same works in case of using Outgoing Response -> Extension Tool.
I can't use Outgoing Response -> Extension Tool as it comes before the Header Databank so Response Header will not be available.
