Hi Ghoti ,

The Problem was something as below

1. We have more than 100 Data types .
2. for one of the data type , we had done certain changes . To validate the DCR while saving we had put certain conditions in Form API .js
3. Something as below
var eItemArray = IWDatacapture.getItem('/resourceSelector').getChildren();
***************
But the item resourceSelector is not present under all Data Types ,

4. So The data type having resourceSelector would save properly and other would give the HTTP Status 500 - java.lang.NullPointerException .

To over come this we used something as below
var a_path=top.gWorkarea;
var b_dctName = getDataType();
if (((a_path.search(/a_new_us/))!=-1) && (b_dctName=="resource"))
{
Code
}

Thanks
