Help please - indexed field in ActionForm

2003-08-14 Thread David Thielen 
Hi;

I've been fighting this all day with no luck. And it has to be a simple thing to do.

I have a form where I have N lines in it. Each line needs to have some text displayed 
and an edit box.

How do I set this up in the .jsp file and in the ActionForm? I've found a number of 
examples on the web but they all have incomplete code and my guesses for the rest of 
the code have not been right so far.

thanks - dave

Haven't used JSTL yet, but let me try this...

 class MyActionForm
 {
   private static final MAX_ENTRIES = 50;
   private ArrayList text;
 
   public MyActionForm()
   {
 text = new ArrayList(MAX_ENTRIES);
  for (int x = 0; x  MAX_ENTRIES; x++)
  {
text.add(); // avoids IndexOutOfBoundsException later in setText
  }
   }
 
   // used by MyAction
   public ArrayList getText() {return text;}
 
   //  Used by Struts
  public void setText(int index, String newText) {text.set(index, newText);}
}
 
 my.jsp
 html:html
   body
 html:form action=MyAction.do
   logic:iterate id=text indexId=index name=myForm property=text
 !-- Note trickery here. Not using html:text --
 Label:input type=text name='text[bean:write name=indexId/]'/br/
   /logic:iterate
   html:submit/
 /html:form
   body
 /html:html

 Hi;
 
 Thank you - this is part of what I need.
 
 Is there any way to iterate through the lines if I don't know 
 up front how
 many lines there will be? I tried the with the c JSTL and it 
 doesn't work.

You could also try the following:

logic:iterate id=text indexId=index name=myForm property=text 
label:html-el:text property=text[${indexId}] /
/logic:iterate

You could also make use of the nested:iterate and get rid of the
name=myForm, but this a bit more advanced.

Don't forget to put :
%@ taglib uri=/tags/struts-html-el prefix=html-el %

HTH,

Hi Dave,

There was a good thread about using indexed properties a little over a week
ago (7/28-7/30).  Find that thread and you should find all of the answers
that you need in order to use and process indexed properties on your form.
Even though the thread wanders a little, everything that you need is there.

Nick

You could also try the following:
