Unable to get and set value of checkbox

Hello Form API Experts,

I need a help. I have a check box item "show_abstract"in my DCT. Requirement is, In a replicant, If the chekbox is uncheked at any level, so all the checkboxes under child replcants should be unchecked.

I am able to retrieve the Container Array and number of child but ot able to get and set the value as per the requirement.

Attached is my code, could anyone help me / suggest how to do that. I dig devnet posts but could not find a right help.

Please look for the attached DCt code and following Formapi code.

Thanks in Adv.


function init()
{

 IWEventRegistry.addItemHandler("/section/Top Headlines/headlines_ap_mods/subsection_headlines/show_abstract","onItemChange", setCheckBox);
}

function setCheckBox()
{
alert("calling...");
var replicant = IWDatacapture.getItem("/section/Top Headlines/headlines_ap_mods/subsection_headlines");
alert("Current replicant name is .. "+replicant);

var replicantArray = replicant.getChildren();
alert("Number of childerns.."+replicantArray);

var numberOfItems = replicantArray.length;
alert(numberOfItems);

 for (i = 0; i < numberOfItems; i++) 
 {
  alert("its calling....");
  alert("replicantArray.getName......."+replicantArray.getName());
  //alert("replicantArray.getType....."+replicantArray.getType())
  //alert("replicantArray.getValue...."+replicantArray.getValue());;

  var paraItem = replicantArray.getName();
  alert("Para item is...."+paraItem);
  var para1Item = paraItem.getItem("/show_abstract").getValue();
  alert("Para value is...."+para1Item);

 }
}

I couldn't find the one end tag for container, is the attached dct code correct ?
Are you able to get all the valid values in your alerts ?

Sorry, the end container tag is there in my actual code. this was the type error while creating the post.

I am getting all the alerts except the last one...

Any idea of the solution...

If you want to get the value of any container item then you should use something like below

/section[1]/ subsection_headlines[1]/ show_abstract

Try to look into FormAPI Developer's Guide for more details..

I don't have time to look through all your code right now - but you really should code item handler functions as taking a parameter - which is the IWItem that changed (somehow) to trigger the handler function.

Once you have that, you can use it's name to reference parent and sibling elements. You do use getChildren() - which is the right method for accessing replicant instances - but if you're trying to access a checkbox - I believe you need to do something like:

var cbval = cbitem.getOptions()[cbitem.getValue()].value;
...
cbitem.setOptions()[cbitem.getValue()].value = false;
