Re: Dynamic form fields with s:div and ajax

[Kropp, Henning]

Hello Gainty,

thanks for your reply and effort!

I do specify the href as />. Sorry I left that out. This calls the AddObjectAction, which 
populates the List of objects in the prepare method. This works greate! 
But I simply cant target the div with the action in the div.


In your doc you use a static jsp where I use the Action to render the 
jsp and initialize a List of objects. Than I want the same div and the 
same Action to render the same jsp with the previously initialized List 
of objects and in the action do something to the List either delete or 
add an object. And either way I try its not working.


Targeting the same div (in your doc 'one') results in not having the 
list on the request. Using the formId results in not getting the the 
list on the request. I know it works if I leave out the target on the 
div (in your doc 'one') but still the div needs to be rendered again to 
make it visible. It works when I target a different div. But how do 
override the other div.


regards

from doc located at 
http://www.roseindia.net/struts/struts2/struts2uitags/div.shtml
you would either need to specify where the href value is coming from
   

  id="one"
  theme="ajax"
  href="%{test}">



OR


use the supplied value from property

  Output: 
  Firstname : 
  




for results returned from action class populating a div tag
Div 1

Subject: Dynamic form fields with s:div and ajax

Hello,

I am trying a common scenario, where I want to dynamically create form 
fields and either add or remove some fields. The fields are a List of 
objects. I using the following approach described in short:


AddObjectAction:
List myObjectList;
   prepare(){if == null (3x) add ... else add 1x}
   String delete(){ myObjectList.remove(int listPostion) }

home_jsp:

  
  formId="form"> 
   


addObjectAction-success.jsp:

  
   
 
  ..

   href="%{deleteObject[#stat.index]" />


This works, but does not refresh the div objectsDiv. Using target does 
not work because objectList does not get onto the request, without 
target the objectList is on the request. I tried to set the objectList 
as a param to s:url deleteObject, this kind of works but results in a 
param intercepter exception (haven't tried a custom converter yet).
When having the div put the fields from formId="form" onto the request 
it only puts the fields onto the request that itself does not hold. In 
example only the 'anotherField'.


I think this should work this way. Why does setting target result in 
removing the myObjectList on the request? Why does s:div formId not put 
the fields on request itself holds?


Many thanks in advance

Re: javascript in returned jsp through xhr

Dear Gainty,

vielen Dank for your reply. I am very sorry but I cant supply you with a 
url. What I load into the div is the following:


<%@ include file="/common/taglibs.jsp"%>

   
   ..
   
   

src="${ctx}/scripts/calendar/calendar.js">
src="${ctx}/scripts/calendar/calendar-setup.js">
src="${ctx}/scripts/calendar/lang/calendar-${pageContext.request.locale}.js">


   Form.focusFirstElement(document.forms["traitForm"]);
   Calendar.setup(
   {
   inputField  : "form_start",  // id of the input field
   //ifFormat: "%m/%d/%Y",  // the date format
   ifFormat: Calendar._TT['TT_DATE_TIME_FORMAT'],
   showsTime   : true,
   singleClick : false,
   button  : "button_start"// id of the button
   }
);


I use the following technique to load it into the div:


   
   

  

   cssStyle="width: 100%;"
   loadingText="getText('Loading')" >


The selectTraitPage-action returns the jsp with the jcalender. The 
problem is, that clicking the button than does not result in a calendar 
view. I can use it when loaded not in the div.


I simply dont know why and are very grateful for your help. I believe 
its a matter, that the imported calender.js and/or prototype.js (which 
is needed for the calendar) can bind to the button!? So it fails.


Thx,
Henning
