Groovy Script Runner issue

[Roy Chapman]

We have created a workflow that relies heavily on the send custom email post function functionality that script runner provides.

In the To Issue Fields: I specify a custom field which is a multi-user selector field and get the below error no matter if I specify one user or multiple.

v3.0.7 doesn't fix it.

Below the stack dump generated in logs when the post function is executed.

Are you sure the variable you using the split() function on is mandatory? Looks like the value is empty, which disables ability to run split() on your variable.
