Hello,
I used the normal <select> and <option> tag and built the form by hand. But on
this way, I lost all the save mechanisms from struts (if the page is reloaded
all the dropdown value are lost).
I didn't find a working solution...
So I tried again with the struts tag, and I did:
<s:iterator value="questions">
<s:property value="questionId"/><br/>
<s:property value="questionName"/><br/>
<s:select key="??????????????" list="answers"/><br/><br/>
</s:iterator>
- I iterate on the list "questions" (return by the function:
List<QuestionObject> getQuestions() in the action class) with the iterator.
- I display the id and the questionName
- Then I would like to generate for each question a drop down list with the
answers (return by the function: List<String> getAnswers() in the action class)
The form is properly generated, all the questions with dropdown are displayed...
But how can I save all the values of the dropdowns in my bean?
I thought maybe with a list or a table attribute in the bean, with getter and
setter...
Any Idea?
Thanks and regards,
Matthieu

Unfortunately the <s:select> tag doesn't work like the <select> HTML element.
If that's what you are trying to do you could either set up the list to be
displayed in the action and reference it in the <s:select> "list"
attribute, or you could just use <select> and <option> and build it yourself.
