No Exception Defined for System Errors

Question

hi,
I am capturing system messages through an Exception error handler in the block step of Integration Processes.
Its a IDOC -> XI -> HTTP Receiver scenario.
When i execute the scenario, i see an error in the workflow in the Block Step. It shows an Error which says "No Exception Defined for System Errors", though i have a Exception Branch in the Block step.
Any clues why i am not able to capture the Exception errors and send it through email.
Its failing at the Block step.
More details on the scenario:
1. Start
2. Receive Step - Asynch - IDOC
3. Block Step - with Exception name as "TimeOut"
3.1 Exception Branch with exception handler as "Timeout"
  3.1.1 -  Transform Step - to transform a Exception message(with just one field) to "Error" message  (with 5 fields)
  3.1.2 - Send Step - send the "Error" message through email
3.2 Deadline branch set to 1 minute
3.3 Switch step
  3.3.1 Transformation step - to transform the IDOC to XML
  3.3.2 Send step - Synch - request xml and response xml defined in this step
4. Switch Step
4.1 - Transform step - transforms the idoc and xml response to the actual error
4.2 - Send Step - sends the actual error to the email message using MAIL adapter.
Any tips would be grateful.
Thanks,
Tirumal

Stefan -
In step 3.3.2
I did find the property exceptions and assigned the exception branch in the block and ran the scenario, now i get an error saying that : "Exception Timeout Occurred."
I went through the Technical Details of the workflow and the error displayed there is "Exception 'Timeout' caught and transferred to the exception handler'.
In step 3.1.1
I get an error saying "No Payload found'.
Does this mean its not able to capture the message text.
Thanks in advance,
