JCorrelate has a new feature where you can analyse the request and response details of a parameter. To use this feature, you need to click on the parameter name in the list of dynamic parameters identified by JCorrelate. You can also feel that the parameters list page is cozy than before.
JCorrelate also highlights the parameter value with its boundaries in the response tab. The response tab also holds all the response information related to headers and data.
You can navigate to the request tab to get an idea of your request type, headers and data.
JCorrelate will make appropriate validations in your JTL log and your JMX script, if you choose to update your parameter value.
