Hi,
I have an application, which is currently deployed on a server and is working perfectly fine.  I am trying to provision a new server and have moved the application across.  The issue i am facing is that the modal window that comes up when the application is processing, which states 'Loading' has stopped.

Furthermore, more critical is that the application has finder, which pop-up for user to select a record.  When the user clicks on a record, it should typically take the data from the pop-up window into the base form and close the window. 

In case of the new server i am getting the following Java script error.  "Unable to set property 'value' of undefined or null reference"

As mentioned in my statement above the application works perfectly fine in the current production environment. 

Your inputs and help will be very valuable i have spent  a lot of time reading to find the issue.  But have failed.

It is kind of urgent.

Hello Pranay,

Such an error seems like an issue with accessing the input elements that you populate. I advise debugging the code to see what objects are returned. A common issue is the the ClientIDs are not used and thus, when the page hierarchy changes, hardcoded IDs no longer return the expected elements.
