The Behaviour is not working for the Cascading Field when tested on the JSM Portal page using JSM 5.10.0 and above.

Steps to Reproduce

1. Create a Cascading List with some options and add it to any JSM request type.
2. Create a Server-Side Behaviour for the Cascading List and add the sample code below:- 

   def sampleCascade = getFieldById(fieldChanged)
   def sampleCascadeValue = sampleCascade.value
   
   if (sampleCascadeValue) {
       log.warn "======>>>>> ${sampleCascadeValue}"
   }
   

3. Save the Behaviour, open the JSM request type and try to set the value for the Cascading List.

Expected Behaviour

The log output containing a List of values selected from the Cascading List should be printed.

Actual Behaviour

It appears that the if condition is failing, resulting in no logs being printed. 

Additional Info

• When testing on an earlier Jira version, e.g. Jira 9.8.0, the log value is printed as expected.
• The test video is included: test1.mkv

The test video displays the difference in the Behaviour when tested with Jira 9.10.0 against Jira 9.8.0, where both have the ScriptRunner 8.11.0 plugin installed.
