  Cause:
  The error message "Node &1: Cardinality &2 is not allowed" suggests that the cardinality defined for a particular node in your Web Dynpro component is not valid. Cardinality refers to the number of instances of a node that can exist in a particular context. The common cardinality settings are:
  
  0..1: Zero or one instance
  1..1: Exactly one instance
  0..n: Zero or more instances
  1..n: One or more instances
  
  The error typically arises when:
  
  The cardinality defined for a node does not match the expected cardinality based on the data model or the context in which it is being used.
  There is a mismatch between the cardinality defined in the data model and
