Re: Dynamic Form Best Architecture

So you want to build a dynamic UI based on same definitions you get from a web 
service?

I've taken a similar approach only I used XML to hold on to the meta data for 
the UI and Java to process the business logic.

If I were to do it all over I would use Wicket Forms. Why re-invent the wheel?

Have a great day,

 Hi,
 
 Can you give some examples with pseudo data ? It is a bit hard to follow
 what is the requirement.
 If I follow correctly you have a radio group. Depending on the selected
 radio you have to make a call to a web service and render some form
 controls dynamically for the web service response, right ?
 
 You can have just one Panel for the dynamic part of the form. Start with an
 EmptyPanel and selecting a radio will replace it with another one. To
 create the dynamic form controls you will need a set (of Fragment or Panel)
 of all possible controls and just add them to a repeater.

 Hello,
 
 I'm a new user of Wicket and I would like to have your opinion.
 
 Here is what I'm trying to do :
 
 Step 1 : My application calls a web service to retrieve some data.
 
 Step 2 :
 Based on these data the application must build a big web form, this form
 ask
 the user many questions
 (15-20 for instance, most of the time yes/no questions (without submit
 button), sometimes new inputs may appear etc).
 Each time a response is given a new question appears (conditions of
 appearance can be the previous response and / or data retrieved by the web
 service).
 At the beginning all the questions are invisible.
 
 I have multiple options to architecture this :
 
 - Initialize all the panels for each question and make them invisible at
 the beginning. Use Ajax on each Radio Button (yes / no), checkbox etc and
 make them appear.
 The problem as see with this solution is that it forces me to add all the
 panels to the form and the logic of appearance is fragmented in each
 panel
 which handle the question.
 The other problem is that we need the server (Ajax for each response) even
 though it isn't needed once we retrieved the data from the web service.
 The last problem I see is that how do I manage to hide all the children of
 a
 panel if the user decide to go back and change his response to a previous
 question.
 
 - Same as previous but I add dynamically the panel / question for each
 response. However once again
 the logic of appearance is fragmented in each question and it is
 difficult to maintain.
 
 - Same as previous but all in JavaScript. I will need to convert all the
 data from the web service to JavaScript variables not really the wicket
 Way...
 
 - Maybe I could use Nested Forms but I lack the required distance to be a
 good judge. I don't really know if is really the best response to my
 problem.
 
 - Finally What about the form Component panel ?
 
 Note : There are in fact many big forms depending on the user profile.
 
 If you could give me your take on this I will be really grateful.
