Client script oldValue always empty

[Brian Lancaster]

I am writing an on Change script for the change module.   When I try and if (newValue == 'This' && oldValue == 'that') it is not working.   So I did a alert(newValue) along with an alert(oldValue) and oldValue is away returning as empty.   What might be causing oldValue not to return anything?   Just note that newValue is always returning what I expect it to.

Brian,

You can get previous value in Business Rule. I am not sure if that will be helpful with your requirement and fulfill your use case.

I don't think that will work as I do not think these is a way to hide options or add options back in a drop down though a BR.

Same problem, trying to use it on Catalog Client Script.   I need to use oldValue to check what the previous option was so I can reset if needed options that I have removed from a drop down select box.   Example: If field 1 is x remove two options from field 2, if user changes mind and sets first field to y I need to allow those removed options to appear again in drop down field 2.

I have the same problem. Did you find the solution ?

Its been so long.  I think I converted it to a business rule.  I don't work at the company anymore  so I don't have a way to look.  It appears that client script always returns null for oldValue so I'm not sure why they even have it.
