MultiTextEntryDialog closes even if each field is not filled
As object, happens e.g. when you add a new station and don't fill all the fields.
The doc of the classMultiTextE
" Each field must be filled out or the dialog will not close."
Reading the code i can't see this feature, i fixed this in the patch. It 's a bit ugly artifice, but is the simplest that came to my mind.
