Hi, Has anyone managed to catch the exceptions thrown by Appian and

We are using Appian version 6.6.1 by the way.

Integration nodes are generally what cause exceptions (that aren't obvious during design time) and are required to be handled. The method to handle such excpetions differ based on the node that is used. For example, DB nodes come with a provision to pause or exception or continue with error. Web service nodes could be wrapped in a sub-process with a timer/retry logic in the parent model. An automated process to review the process with problem report is another option to handle exceptions.

Here are some links that provide good documentation on error handling/exceptions:

Hi Venkateshr,

Thanks for the links. I have seen some of the links that you provided. In general, most of the those information describe preventive actions as such the errors must be handled/resolved during development & testing stages. Although I don't disagree with the idea, I doubt that we could come across those errors and handle them 100%.

What I would like to do is basically inform the users in an informative and graceful manner that an error has occured (rather than going back to the dashboard page as if nothing happen) and then we can email the corresponding team to deal with the problem. At the moment, we can only do this for any errors coming from the web service by showing a custom error page and send the alert forwarding the fault text or custom error message sent back from the web service. If we can do the same for the other nodes then that we would have a consistent approach to deal with any process exceptions globaly within Appian.

Any suggestion/work around?

Furthermore, it would probably be nice to build a custom plug-in or suggest Appian dev team to enhance the product by introducing a new node to catch the global exceptions within the process model and allow the process designer to develop an exception path starting from that node. Not sure if anyone has developed the plug-in for this (or if it's possible to do in custom plug-in?). I haven't seen it being posted in the "shared components" section. Surely it will be a very useful feature for everyone here :)
