Hi All,

I am going to create CRM input component.In this component passing four parameters (URL,username,Access key and Module ) for extract data from crm module.But module parameter shows list of module like drop down,first three parameters configured in @Datastore and Module parameter configured in @dataset. I have added test button for test the connection using first three credentials using @Checkable and @HealthCheck annotations.once we get connection then we need to select module name from the list.But this list need to generates dynamically using three parameters.Now test button is working perfectly using parameters, but not generating module list as per three parameters facing null pointer exception as per below screen shots.hope I will get perfect solution from our community members.
