Re: Approach to changing value in input field before validation
Well, the user is entering a part number (SKU) and there are times where we’ve specified replacement SKUs. If I find only 1, then I want to replace and continue, but if I don’t, I want to continue the existing validation and maybe it finds a valid part or maybe it gives the user a message. But if I replace the 1 and it’s now in a discontinued state, I need to fail validation and let the user know. It’s not a typical e-commerce app, actually it’s a large CRM system, so there are times where I have to do unusual things to meet the users needs. The current application (desktop) leaves SKUA in the textfield, but gives you the validation messages for SKUB (assuming it fails). I felt that this was more confusing that swapping the input and then showing the user the replaced value along with the validation message that belongs to the new SKU (B) -Lon On Tue, Jul 26, 2016 at 8:07 AM, Martin Grigorov wrote: > Hi, > > I find it confusing that the user enters "A" and if the validation fails > (s)he sees "B". > Me, as a user, I'd ask myself: I've entered "A", why it tells me that "B" > is incorrect?! > > Maybe a better way is to use better error feedback messages than replacing > the user input ?! > > Martin Grigorov > Wicket Training and Consulting > https://twitter.com/mtgrigorov > > On Tue, Jul 26, 2016 at 5:00 PM, Lon Varscsak > wrote: > > > Okay, that works.

Re: Approach to changing value in input field before validation
Hi, I find it confusing that the user enters "A" and if the validation fails (s)he sees "B". Me, as a user, I'd ask myself: I've entered "A", why it tells me that "B" is incorrect?! Maybe a better way is to use better error feedback messages than replacing the user input ?!

Re: Approach to changing value in input field before validation
Okay, that works. Do you think my approach to use a converter is appropriate or should I do it in another place (like validation)?

Re: Approach to changing value in input field before validation
We have made an utility method that uses reflection to set rawinput, and have found this very useful. You set both rawInput and rawInputArray ** Martin 2016-07-26 1:18 GMT+03:00 Lon Varscsak : > Okay, so I have a need…I’m sure I’m going to get “why are you doing that?”, > but I have this need regardless and here’s what it is… :D > > User inputs “VALUEA”, I want to look up something in the database for > “VALUEA”, and if conditions are met, replace that with “VALUEB” and > continue with validation for the new value.
