I seem to be having a problem logging in to the bug tracker. I found Jira issue IDEA-16012. It has been marked as resolved, but the issue is still there. The getter/setter generator should definitely treat Boolean fields as regular objects, as EL languages expect this and will deliver damn near undecipherable errors when a getter for a Boolean is written as 'is' instead of 'get'.
Please fix this. It's really annoying because every time you use the generator you are required to manually change it.
