CGI_task following an external task - NOT Allowed?

System

Is it true that a CGI task cannot follow an external task?
I have an external task that implements my DD and OD and would like a CGI task to follow the external and display an error message if the DD or OD fails. But the cgi task does not seem to work when placed after the external task. Is the best solution to this -
1. Re-implement the external-task that does the DD and OD as a CGI that includes the error message.
2. Place a dummy usertask betweeen the external task and the CGI task.

?
thanks in advance

A CGI task can certainly follow an extrernal task. However, it won't "pop up" in the user's browser automatically. The user will have to explicitly start the task. It won't matter if immediate="t" is set or not.

Correct - so the first option suggested - recoding the entire externaltask script as a cgitask script would probably be the right idea.

Yes... it is true if you want to open the CGI file just after external task gets completed. The reason for that is there is no scope of calling a user visible file from a process running behind the scene.

Thanks for the help. A CGI that does the OD and DD it is then.

There is one potential "gotcha" you need to be aware of with this solution:

Presumably, you want what was originally going to be in the CGI to be run as the user who invokes it. In that case, what was originally going to be in your external task handler will also be run as that user. So you'll need to make sure that user has permission to perform whatever operations you perform.

Another issue is that CGI has a timeout that may be exceeded by the deployment. Better, in my opinion, to leave the Deployment as an external task and then have a CGI task only for error handling. Yes, the end user must start the task by hand, but it does eliminate the timeout issue.

Alternatively, you could try starting a CGI task BEFORE the deployment task, this task would immediately calls back and then monitor the deployment (via the log file? via an error log?) to see what happens with the deployment.
