Can an issue be in one project and its tasks in a different project?

[Christina Wilkerson]

We have distributed development teams and would like each team to have their own project (therefore their own individual backlog).  We have a workflow where development of an issue is done in one region however there are deployment tasks in two other regions.  We would like the issue to live in Region A but from that issue, spawn deployment tasks (of that issue) to Region B's project and Region C's project.  Is this possible?

You can (with code) spawn issues in other projects.

Sub tasks always belong to their parent, and hence must be in the same project as their parent.

Nic - do you have sample code or could you point to where an example would be?  Thanks!
