Behaviour script fails

[Rob Schalken]

I had the following script in behaviour. This script checks on SW/FPGA label and then enables the setrequired function. This was working fine. But I did an update (have always the latest plugin version, Jira 7.8.1) and now it fails.

<code>

def labelsField = getFieldById("labels")
def revisionField = getFieldById("customfield_12307")

try {
 if ((labelsField.getValue().toUpperCase() == "SW") ||
     (labelsField.getValue().toUpperCase() == "FPGA")) {
     revisionField.setRequired(true);
 }
 else {
     revisionField.setRequired(false);
 }
}
catch (ex) {
 if ((labelsField.getValue().toUpperCase().contains("SW")) ||
     (labelsField.getValue().toUpperCase().contains("FPGA"))) {
     revisionField.setRequired(true);
 }
 else {
     revisionField.setRequired(false);
 }    
}

</code>

Hope you can help me with this.

Hello @Rob Schalken

Could it be that the script is executed on for the issue which has empty labels because in that case it will throw NullPOinterException.

Hello Tarun,

This is not the case. There is a label available.

Can you try "getFieldByName()"

https://scriptrunner.adaptavist.com/5.3.9/jira/behaviours-api-quickref.html

And also since it's labels field then it will be returning a list of values instead of a single value, may be you have to do "list.first()" to get the first value.

Found the problem. The label was not on the screen. So now I added this and it is working now.

That's good to know, no wonder it was returning null. As the only reason it can return null is either it's empty(which I was thinking) or it's not on the screen (which is the actual reason). Please accept/upvote if you felt the answer was useful or might help other users.
