[Gnumed-devel] Validation of data within widgits

[Richard Terry]

I'm somewhat perplexed by Karstens previous explanation of lack of on-screen 
validation in widgits - eg date validation - the explanation that the back 
does the validation.

All very well (as in most database applications). However what the user types 
on the screen is a different matter.

Only allowing back-end validation is a huge time-waster. What happens when the 
data is saved and the user has to then go back to find the relevant screen 
containing the text box with abcdefghi typed in instead of a date (or to be 
realistic say an out of range date - or any format not being able to be 
converted to a date.

The practice of only using backend validation seems ridiculous. No-ones 
programs work like that. Each and every text box needs to be allocated the 
character types allowed to be entered there. Those needing only 4 numbers eg 
postcode_AU should only be allowed 4  numbers, not any number or combination 
of letters etc.

Am I missing something fundamental here????????
