Have you ever wanted to lock down (make read only) the fields in your form when it moved along in your workflow process?  I found a script (I don’t remember where or I would give credit) that will allow you do that from within your form.

All you need to do is place it in the Variables section of your form heirarchy and call it something simple like lockFields.  Then in your form you can call it by using lockFields.LockAllFields(enter your subform or field reference syntax here).

Hope you find this useful.

/* 
*****************************************************************************
Function: LockAllFields 
Description: This function will lock all fields. 
IN: The parent subform. It could also be an element that contains subform
like form1  
OUT : nothing

function LockAllFields(myParentObject){ 
var allChildElements; 
var intNumElements; 
var currentElement; 
var j; 

//Get all the child nodes of the parent element 
allChildElements = myParentObject.nodes; 

//Total number of element in the object 
intNumElements = allChildElements.length; 

//Loop through all the child elements 
for(j=0; j< intNumElements;j++){ 
    currentElement = allChildElements.item(j); 
    //If the element is another subform we'll recursively call the function
    //again 
    if(allChildElements.item(j).className == "subform"){ 
        LockAllFields(currentElement); 
        } 
        //If the objects are fields then set the access to readOnly 
        else if(currentElement.className == "field"){ 
            currentElement.access = "readOnly"; 
            } 
            //Check for exclusion groups - Radio Buttons 
            else if(currentElement.className == "exclGroup"){ 
                for(k=0; k< currentElement.nodes.length;k++){ 
                    if(currentElement.nodes.item(k).className == "field"){ 
                        //set the access for the RadioButtons individually 
                        currentElement.access = "readOnly"; 
                    } 
                } 
            } 
    } 
}//end function
