New Post: Cascading Dropdown Intermittent Issue: Child field not generated

I am supporting our company's sharepoint custom code (new team) and am fairly new with regards to jquery. In one of our sites, we use a simple cascading dropdown to generate the list of values of the Resolution Code field depending on the Reason Code field.

The issue is that in the Production environment, users have reported that there are times where in the Resolution Code is not being generated. This happens whenever they are filling up the fields when adding a new item to the Service Requests list.

This is an intermittent issue so they can't repeat it on purpose. Since I cannot test in our Production environment, I tried doing it in Test but could not replicate the issue. I have asked the user to try and reproduce in Test but are unable to do it now because of their workload.

The SPServices version we are using is 0.7.1a.min.js

The SPServices command is called from a custom js file named forms.js "$(document).ready(function()" function

We are accessing from the company Intranet, using the company standard machine where the browser is IE Version 8.0.7601.17514

There are several variables to consider that may attribute to this issue. Would you be able to guide me as to narrowing down and getting to the root cause?

Do you see any compatibility issues with the browser & SPServices version?

Let me know if sending the forms.js file will help

Thanks in advance!
