Scriptted post function using groovy to swap the component value

[Vishnukumar Vasudevan]

I am looking for a groovy script to swap the Component field value as a post-function. Ex: On clicking on an action, the component value must change from "A" to "B". The script I'd tried is given below,

import com.atlassian.jira.ComponentManager
import com.atlassian.jira.util.ImportUtils
import com.atlassian.jira.component.ComponentAccessor
ComponentManager componentManager = ComponentManager.getInstance()
compList = ["A":"B" , "CAT":"DOG"]
if (compList[componentManager] != null)
{
issue.setComponents(compList[componentManager])
}

What's this supposed to do? compList[componentManager] I'm not going to write this for you. I don't mean this sarcastically, but do a few groovy tutorials.
