New EA 12 Operation & Attribute Dialog error

[ringle.lai]

Hi, I found a bug in EA 12.
When I use the Operation Dialog, it will become disable if I delete the final new line in the dialog.
It will not show anyway, and I can't new any operation or attribute.
Anyone could told to me how to solve this problem?

I know what's happened!!
There's a new Feature called "Filed Chooser".
If I drop the "Name" Field, the "New Operation" or "New Attribute" will be disappear!!
So I can't add any new operation or attribute until I restore the "Name" filed!
