UnsupportedOperationException when using Code Completion
davidbauer99 opened this issue · comments
I frequently see the included error when using RubyMine's code completion features (ie: tab complete or enter complete). When this happens, hitting tab will clear the partially entered code symbol and close the completion window. For example:
- Have a list named
my_list. - Start typing
my_list.sortwhich brings up a code completion dialog - Navigate to
sort_byin the dialog - Hit
tabwhich will revert the current line tomy_list.and close the dialog.
RubyMine Version: 2022.2, Build #RM-222.3345.111, built on July 25, 2022
Plugin Version: 1.6.1
