Deleted Retrieving the error message

Can you be more precise please ?
Is it that you want to read the error message ? Or you want to get it in a variable and use it after ? Or you want to send it by email ? or to a file ?

When an action has an error, these variables are set like this :
- CORE_RET_CODE = -1
- CORE_RET_MESS = a single line error message
- CORE_STACK_TRACE = a more detailed error (java stack trace in most cases)

You can refer to these variables from a SqlOperation like this :
INSERT INTO yourtable VALUES (${../ACTION_NAME/CORE_RET_CODE}$, '${../ACTION_NAME/CORE_RET_MESS}$')

(replace ACTION_NAME with the name of the action in error).

And then you can develop a process which reads the table and sends data by email.

From a mapping, the syntax is the same.
The idea is to find the path to the desired action. The path to an action can be found in the CORE_PATH variable of the executed action.

Hello,
Actually this is possible with a Scripting action relying on the Runtime's API.
We can prepare an example of a tool which does this, in the next few days.
