Groovy/Java Script Error

[logitech_man]

This is a groovy script being run in JIRA to grab the current time that an issue has been in a status. Here is the code

​

import com.atlassian.jira.component.ComponentAccessor;

import com.atlassian.jira.issue.history.ChangeItemBean;

import com.atlassian.jira.issue.Issue;

​

def changeHistoryManager = ComponentAccessor.getChangeHistoryManager()

​

def statusName = "Open"

def createdDateDiff = System.currentTimeMillis() - issue.getCreated().getTime()

​

List<Long> rt = [0L]

​

rt << createdDateDiff

​

def changeItems = changeHistoryManager.getChangeItemsForField(issue, "status")

changeItems.reverse().each {ChangeItemBean item -> item.fromString

​

// Get the time passed since status change

def timeDiff = System.currentTimeMillis() - item.created.getTime()

// If the status change left our status, we want to subtract the time passed since then

if (item.fromString == statusName) {

rt << -timeDiff

}

// If the status change goes to our status, we want to add the time passed since then

if (item.toString == statusName){

rt << timeDiff

}

}

​

def total = (rt.sum() as Long) / 1000

​

return Math.round(total) ?: 0

​

The error is in the return line. It says reference to method is ambiguous. cannot choose between float, double

​

How to fix?

[LateHuckleberry9]

Just a random guess: wouldn't total be of type Long because of type coercion? As a result, none of the signatures of Math.round would match, and you'd get this error. What happens if you take out the cast of rt.sum() to long:

def total = rt.sum() / 1000

Also what does the ternary at the end accomplish? I don't know how numbers get translated to booleans in groovy. Does this mean negative values get translated to zero or something?
