fix: make user_src_input generate valid javascript user_src_input used to generate False if edit_ok == False in this statement: tal:attributes="onblur python:edit_ok and 'split_name(this)'; but False isn't a boolean in javascript, so it throws an error in the console. Changed to use: tal:attributes="onblur python:'split_name(this)' if edit_ok else ''; which generates an empty onblur if the field is not editable.
