NESTED TAG PROBLEM .....

[Dragan Kocic <ki...@web.de>]

I trying to work with this nesteg tags from "jakarta-struts-20020422" but I
get no results, even no exceptions ... I got crazy ..

I have a Bean called "FrageBean" filled with some attributes (Strings and
Integers)
I fill a hashtable with some of these Beans ...
put this hastable into the Session ...


	HttpSession session = request.getSession();
	session.setAttribute("hashtable", hashtest);


In my View I try to use the nested tags like this ....



	<nested:iterate name="hashtable" property="value">
   		<nested:write name="FrageBean" property="frageText">
	</nested:iterate>



the Property "frageText" should return the String-value ...
I tried it with Java directly inside the JSP ... like this:



java.util.Hashtable hash = new java.util.Hashtable();
hash = (java.util.Hashtable)session.getAttribute("hashtable");

de.plenum.happySheets.beans.FrageBean fbean = new
de.plenum.happySheets.beans.FrageBean();

fbean = (de.plenum.happySheets.beans.FrageBean)hash.get(new Integer(0));

String test = fbean.getFrageText();

out.print("XXX -> "+ test);



...

On this way there is no problem, but I don't want to have this Javacode
inside the JSP
Where is my fault...

THankz in advance !!!!!!!

The nested tags work off a structure defined within a bean. Not a 
collection itself. So wrap the hashtable in a bean and you're on your way.

You're not using a form obviously, so you'll need the <nested:root> tag 
to start everything off. Point this to the name you put the bean into 
your session with (currently "hashtable"), and it'll be fine. The nested 
tags work off the premise that they relate to each other. They always 
look up the tag hierarchy until they see a relative tag. Now there has 
to be a tag to start it all, this is what the <nested:root> bean has to do.

Hopefully, this done it will start working as expected.

If you're still having trouble, there's a primer and a tutorial which 
will walk you through all the steps of using the tags.
