How do I change a projects name without my sprint tasks disappearing?

[Axel Gunn]

If I modify the name of an ongoing project, all tasks /stories in my Greenhopper Wall/sprint are gone.

The re-appear if I change the project name back to what it was.

Check the filter query behind your GreenHopper board. You'll want to update the project name in the query by editing the query:

project = "New Project Name" ORDER BY Rank ASC
