how to setValue for an hidden item inside a container onReplicantAdded event?

Hi,
I want to set the value of a hiddenitem inside a container with a randomly generated value. I have written the following javascript&colon;This doesnt set the value in the hiddenfield for the first replicant that comes by default, but does set the randomvalue for the replicants that are added after that.Also I am not able to save the dcr..It throws some script error and doesnt save. Says
"Save was unsuccessful. Invalid category/type null was received."
The script error thrown is
"Cannot execute code from the freed script"..

Can anyone help me out this ?

This is the script i wrote:
function init()
{
alert("init called");
IWEventRegistry.addItemHandler("/rootContainer/Container","OnReplicantAdded", initialHandler);
initialHandler(IWDatacapture.getItem("/rootContainer/Container"));

}

function initialHandler(typeItem)
{ var randomnumber=Math.round(Math.random() * 101) + 1;
alert(randomnumber);
typeItem.getChildByName("hiddenItem").setValue(randomnumber);
alert("done");
}
IWEventRegistry.addFormHandler("onFormInit", init);

Hi,
Thankyou so much. The issue I had in setting the value for the first replicant's item is solved. But I still am not able to save the dcr. It throws the following script error when I click on save.

Error is
Object doesnt support this property or method.

To get hold of the property or method in use, please attach your script/DCT.

Posting your code would help, but check what functions you have keying off of the onSave event.

Please Find attached the datacapture.cfg and Script.js files.

Hi,
I resolved it. The problem was that I was trying to set the randomnumber generated by Math.Random which is not a string to the hiddenitem using setValue() function. Now I am converting it to String and setting and thus working..

Thanks a lot for ur support
