If i have an editable p:selectOneMenu the edited value is not saved when the dropdown is closed.
This is reproducable in PF-Showcase.
Steps to reproduce:
1. click on the dropdown-button 
2. edit the input field: type 'hugo'
3. click on the dropdown-button 
=> the dropdown is closed and value 'hugo' is saved
4. click on the dropdown-button 
5. edit the input field: type 'not working'
6. click anywhere 
=> the dropdown is closed but value 'not working' is not saved
