Prestamo = Loan Ejemplar = a Copy (of a Material) Socio = Library member. Listado = List Selecciono = Selected Alerta = Alert Anyway you could ignore most of the spanish stuff since the problem is how should I call openModal so it blocks the main window. So, add loan creates a Loan new, then does an openModal on UILoans where you load the Loan data: CopyID, MemberID, etc. if you hit OK some conditions should apply for it to be added on the Loan database (anOrderedCollection). openModal on UILoans just popups a newPluggableDialogWindow with textEntries to fill the Loan fields before adding it to the database.

I guess it depends on the cost to you or your organization of having someone you don't want/know getting access to information that should be password protected. A thorough argument for bcrypt rather than md5/SHA is made here: http://codahale.com/how-to-safely-store-a-password/ I use it because for roughly the same number of lines of code passwords are much harder to crack.

You can do that using Morphic, but this is quite tricky (in fact, you need to remove all the sub widgets, then change their layout and re add them) Spec provides a simpler way to do it.
