  Error Message
  WD601: Required entry fields not in event container
  
  Cause
  This error occurs in Web Dynpro ABAP applications when the framework expects certain input fields (parameters) to be present in the event container during an event processing, but these required fields are missing.
  
  The event container is a data structure used to pass input parameters from the view (UI) to the event handler method in the component controller or view controller.
  When a UI element (like an input field) is marked as required (mandatory), the framework expects the corresponding value to be present in the event container when the event is triggered.
  If the required fields are not bound properly or not passed to the event container, the framework raises this error.
  
  
  Typical Scenarios
  
  The input field is marked as required in the UI (e.g., required="true" in the view layout).
  The event handler expects the input value to be available in the event container.
  The input field is not bound to a context attribute or the binding is incorrect.
  The event container does not contain the required attribute because the data was not passed or updated correctly.
  The event handler tries to access the required field from the event container, but it is missing.
  
  
  Solution
  
  
  Check the Binding of Input Fields:
  
  Ensure that all required input fields are properly bound to context attributes.
  The context attribute must be part of the context node that is passed to the view.
  
  
  
  Verify the Event Container Parameters:
  
  Make sure that the event handler method receives the required parameters.
  If you are manually manipulating the event container, ensure that the required fields are added.
  
  
  
  Update the Context Before Event Trigger:
  
  If the input fields are updated by the user, ensure that the context is updated before the event is fired.
  Use wdContext->getElementBinding()->getProperty("propertyName") to check if the property is filled.
  
  
  
  Remove the Required Flag if Not Needed:
  
  If the field is not mandatory, remove the required="true" attribute from the UI element.
  
  
  
  Check for Custom Event Handlers:
  
  If you have custom event handlers, verify that they correctly handle the event container and do not remove required fields.
  
  
  
  Use Breakpoints and Debugging:
  
  Debug the event handler to check the contents of the event container.
  Use the Web Dynpro debugger to inspect the context and event container.
