Hi,

I assume there is no wait state in your process (for more info http://www.activiti.org/userguide/#bpmnConcurrencyAndTransactions). It means that when one step fails transaction is rolled back to the start -> Start process fails.
You can make steps asynchronous and in that case you can limit transaction boundaries.

Actually what you can do, is to catch the error and forward the process to some wait state like recieve task. Later on you can query the waiting task and send a signal to resume or cancel the task.

Another way is to use asynchronous tasks. These tasks are executed as job. You can write a custom job executor to retry it on demand. The first appraoch is much simpler, I have to admit.

I created a sample, but it seems that I cannot post picture.
