Another "Unfortunately, a Serious Error Has Occurred..." for Validator 1.3

We can no longer run the validator with our SDTMs as we now get this message with the new V1.3:

java.lang.IllegalArgumentException: The property Subname is not set at org.opencdisc.validator.model.EntityDetails.getProperty(EntityDetails.java:286)

at org.opencdisc.validator.model.EntityDetails.getString(EntityDetails.java:264)

at org.opencdisc.validator.report.ExcelReporter.createDetails(ExcelReporter.java:752)

at org.opencdisc.validator.report.ExcelReporter.closes(ExcelReporter.java:154)

at org.opencdisc.validator.DefaultValidator.Validate(DefaultValidator.java:425)

at org.opencdisc.validator.gui.ValidatorClient.ProcessMonitor.run(ValidatorClient.java:1720)

Any help will be appreciated.

Kind regards,

Brian
