>          Issue Type: Bug
>    Affects Versions: 1.5.0

> Create a flow where a processor has scheduling strategy set to event-driven with concurrent tasks set to 0. Start version control on the flow, and them try to import a new process group using the flow from previous step.
> The error is because during import we set the concurrent tasks value before the scheduling strategy, and StandardProcessorNode line 630 throws an exception if the tasks is < 1 and strategy is not event driven.
> The exception also does not report any message so it is hard to figure out what the issue is.
