In DevTest 9.0, multiple times now, I've created a a new custom String Generator Pattern and used it, only to then have the newly created generator pattern just disappear. Whenever I click the "Save" button (disk icon) at the bottom of the "Patterns" view, nothing happens.
When the custom pattern disappears is pretty random. Sometimes the pattern will disappear while navigating through other views in the Workstation. Sometimes it's gone after restarting the Workstation. Sometimes it's still there when restarting the Workstation.
Is there some trick that I'm missing in order to make a custom String Generator Pattern persist properly?
