Hi,
One possible workaround that comes in my mind is to have a DataForm for each
widget, assemble them into an ArrayList inside the Action class, according to
how you want the q/a to appear. When submitting this page (collection of
forms), just do the reverse to know the user response to each widget rendered.
Please let us know, your workaround. I guess there can be more brilliant minds
who have much greater solutions to this.
Thanks and Regards,
Thomas Joseph

Subject: Re: dynamic checkboxes and radio buttons in one group
Hi
I think i didn't express clearly in my previous mail.
I will try to do it again.
In my Configuration file i can have any number of questions, for each
question i store question text and some kind of flag to indicate if i should
render single checkbox or 2 radio buttons.
If i render checkbox then its value is "Yes", if i render 2 radio buttons
values are "Yes" or "No".
My config file is read in action that prepares me a page with questions.
Reading configuration is the only place where i can figure how namy
questions i need to present. Cause for each question i can have only one
answer (one of the radio buttons selected or checkbox checked) i want to map
all answers for questions to a single action form property - let's call it
questionAnswers. I do not wanna to have a fixed number of properties
indicating answer for question1, answer for question2, answer for question3
...
Please take a look at example:
Question1:
Do you like struts
Answer:
YES NO (2 radio buttons)
Question2:
Do you like yourself
Answers:
YES (checkbox)
Question3:
Do you feel like a shower
Answers:
YES NO (2 radio buttons)
Question4:
Do you like struts-mailing list
Answers:
YES (checkbox)
Submitt.
After the submission button is pressed i would like to have my action form
property that conforms to these radiobuttons and checkboxes looks like this
["Yes","Yes",null, null] . It indicates that user selected yes radio button
for question1 , chcecked checkbox for question2 and didn't select/check any
answer widget for question3 and question4.
Obviously after submission form need to be validated. Form can be invalid if
for some of these questions answer need to be made.
If form is not valid it should be redispalyed and previously selected
widgets need to be shown.
My action form is stored in session scope.
I hope that;s clear and i belive that someone can help me...
