It looks like there's a bug re-enabling the snippets feature after first disabling it. I tried the Reset Windows to Factory Settings option, which worked, but it was not apparent right away. It wasn't until I re-loaded SQL Developer, after resetting windows, that I was able to see snippets again. I ran through a few test scenarios to see what was causing the issue, and came up with these results.
- After resetting windows the first time, I had to re-start SQL Developer to view snippets.
- Once the first reset and reload was done, each time I disabled and re-enables snippets, I still had to reset my windows, but it would show up immediately after reset.
I think that there may have been something carried forward from my previous preferences that was cleared the first time I reset windows and just required a restart to take affect. Now I can consistently reproduce the bug just by disabling snippets and re-enabling them.
Thanks for the reset windows tip
