ScriptRunner Behavior: fill Field option based on another Field option

[Timothy Ryner]

Total scriptrunner noob!

I have two dropdown fields that I am attempting to tie together one the create/edit screens.  The idea is to allow a user to pick an option in either field, and the other field will populate immediately with the appropriate value.  

Fields:

• SWID Name
  • one one one
  • two two two
  • three three three
• SWID #
• 111
• 222
• 333

If / Then:

1. If user selects SWID Name == "one one one" 
   then set SWID # == "111"
2. If user selects SWID Name == "two two two" 
   then set SWID # == "222"
3. If user selects SWID Name == "three three three" 
   then set SWID # == "333"
   
4. If user selects SWID # == "111" 
   then set SWID Name == "one one one"
5. If user selects SWID # == "222" 
   then set SWID Name == "two two two"
6. If user selects SWID # == "333" 
   then set SWID Name == "three three three"

My script so far is just an attempt to get something super simple to work.  Once I have the basic recipe, I'll build it up from there.  

import com.atlassian.jira.issue.IssueInputParameters
import com.onresolve.jira.groovy.user.FieldBehaviours
import groovy.transform.BaseScript
import com.atlassian.jira.component.ComponentAccessor

@BaseScript FieldBehaviours fieldBehaviours

def SWIDNumField = getFieldById(getFieldChanged())
String SWIDNumOption = SWIDNumField.getValue()
def SWIDNameField = getFieldByName("SWID Name")


if (SWIDNumOption == "111" )
{ SWIDNameField.setFormValue("one one one")
}

else if (SWIDNumOption == ("222") )
{ SWIDNameField.setFormValue("two two two")
}

else if (SWIDNumOption == ("333") )
{ SWIDNameField.setFormValue("three three three")
}

else 
{
SWIDNameField.setFormValue("None") 
}

 Any help is greatly appreciated!

I have not found a good way of learning Groovy, besides attempting to solve problems like this.  If there is a good course out there to logically learn how to groovy, I'm open learning and solving this on my own.
