As a user, I want to see the error/warnings messages on the same page from where they were raised

The user will need to compare the error message with the actual data he has edited to understand better what need to be changed.

This is applicable to reserver, release/save and release/release actions.

While having the error/warning message on the form screen (reserve or release), we'll be careful to 2 things:

• not to move the preexisting widget in the screen because of the new message (eg on release/Save, now the SAVE,RELEASE buttons are pushed down when an error message appears)
• that the error message is clearly visible when it appear (e.g. not to have it on top of the screen while the user have scrolled down the screen to click on the button)
