RE: What are indexed struts-html tags and how to use them?

2003-06-11 Thread Sandeep Takhar 
I personally use nested tags because they have better
support for this kinda thing.

Here is a good place for a tutorial.

http://www.keyboardmonkey.com/pilotlight/index.jsp

Go to the bottom and click on the monkey[0] tutorial.

Keep in mind the struts-basics for how it sets values
on the submit.

I have not tried this myself and I don't know what the
exact api you need is for the form bean so that it
will set the values when you submit..  What is
suprising is that the Person getPerson(int index) type
of api is not required.  That is pretty good.

To be honest, if I had to do it again, I would learn
the nested tags first and if I needed to subclass for
my own functionality I would subclass the nested html
tags.  It is a bit more of a learning curve, but once
you have the concept it is smooth sailing and you can
do a lot more.

A big advantage is that you don't have to have
everything on a single page and can have

nested:iterate
 - jsp:include

Always used nested:root as the first tag in the
included jsp page!

Some things to remember are that unlike their
equivalent tags, you should be using a name property

for example:

bean:write name=name property=property/

you would use

nested:write property=property/

So which bean is the write using??  The last 

nested:nest, nested:form, nested:iterate that it
finds.

Now html tags never use a name property since they use
the form that was identified by your 

html:form action=

This line creates the form according to the action (if
it didn't exist in the scope specified in the
struts-config.

nested-html tags will use the nested bean they are
found in based on the last nested:nest, nested:form,
nested:iterate tags that they are found in.

The other important concept is to understand that how
struts handles the form population for you on a
submit.

This is a lot to understand and I may not have
explained it properly... Check out the tutorial and
remember that whatever time you spend now is well
worth it.

  You form bean class will look like this:

  Could you give me more insight on this
  
  Do we have to code the Person class with

   public void getPerson(int index) { ... }
  
  Shouldn't that return a Person object, or at the

  rather than void?

  I wrote a long FAQ description in the
 documentation
  about this, and I'm
  still not sure I can adequately answer this
  question, as it can be
  somewhat confusing.  You could read that at 
  http://jakarta.apache.org/struts/faqs/index.html.
 
  Select the indexed
  properties link.
  
  Basically, you use indexed tags when you want the
  resulting name of an
  HTML component to reference array indexes, so you
  can move values in and
  out of a collection/array in your form bean
 instead
  of scalars.
  
  The indexed tags work along with either the
  logic:iterate or
  c:forEach tags.
