Making text readonly as read-only on the basis of validation script

Sajjad Ali Khan (313952) | asked Aug 27 '15, 6:02 a.m.

Dear All,

I need to create a validation script where the scenario is:

1, There is a custom attribute which has YES/No radion buttons

2, There is text field

If user click No on the radio button then the text field will become read-only, following is the script which have created but its not working and giving some errors in a log which is also available below, i have also define it within RTC client > Workitems > Attribute Customization > Validations

Please help me to resolve this issue and achive what i want to achieve





(function() {

var WorkItemAttributes =;

dojo.declare("org.example.workitems.providers.testvalidation" , null, {

matches: function(workItem, configuration){

var rfc = workItem.getValue("arabbank.attribute.rfcisaproject");


if(rfc == "arabbank.enumeration.rfcisproject.literal.l2"){

return ("arabbank.attribute.EPMOReference").readOnly = true;


return false;




Log from the script:


!MESSAGE Error invoking validator

The script format is a "condition" script, why do you call it a "validation" script? You have made a condition script in a previous post (with an incorrect conditional testing though), why don't you just follow it as an example?

In the script above, this line is absolutely incorrect.

return ("arabbank.attribute.EPMOReference").readOnly = true;

The "another script" is a condition script, not a validation script. You use a validation script to ensure the attribute is mandatory. You use a condition script to make the attribute read-only.
