Behaviour script fails

Question

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.



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);
 }    
}

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.

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

Can you try "getFieldByName()"

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.
