behavior Get timespent values

[Omprakash Thamsetty]

How to get timespent value in behavior and set the value zero 0 if timespent is null.

I am getting below error with my code.

Here is my error

java.lang.NullPointerException: Cannot get property 'timeSpent' on null object

import org.apache.log4j.Category
import org.apache.log4j.Logger
import org.apache.log4j.Level
import com.atlassian.jira.issue.IssueManager
import com.atlassian.jira.component.ComponentAccessor

def issueId = formContents["id"]
def issue = ComponentAccessor.getIssueManager().getIssueObject(issueId as Long)

def TTSpent = issue.timeSpent?: "0"

def TTSpentVal = TTSpent as Long

//def TTSpent = issue.timeSpent as Long

if(TTSpentVal){ //Keep the Remaining Estimate from going into a negative number
TTSpent = 0;
}

def TimeSpent = TTSpentVal / 3600
//log.debug "time spent ${TimeSpent}"

def REst = totalEstimateDEVBA - TimeSpent;
//log.debug "Remaining est ${REst}"

def remainingEstimate = getFieldById("timetracking_remainingestimate")
def remainingEstimatestr = REst.toString() + "h"
remainingEstimate.setFormValue(remainingEstimatestr)

Does anyone has any idea to convert null to zero in code.

@Omprakash Thamsetty 

Your problem is with the issue object itself , it return null.

@Mohamed Adel yeah. its return null but how to set zero if it is null in my code ? This is in behavior

look like some thing below

TTSpentVal = issue.timespent

def TTSpentVal = 0

if(TTSpentVal){

     TTSpentVal1=issue.timespent as Long

}else{

 TTSpentVal1=0

}

but it is not checking value and setting zero. how to check value as null and set zero

Try to update this line : 

def TTSpent = issue.timeSpent?: "0"

with:

def TTSpent = issue?.timeSpent?: "0"

Note : Your  return null object, in this case you are not checking the timeSpent value as the object itself is not exist therefore, it has no property.
