Struts config :
 

Code :
  1. <form-bean name="listePlattsPrixForm" type="org.apache.struts.action.DynaActionForm">
  2.   <form-property name="lines" type="com.total.total.forms.platts.PrixBean"/>
  3.   <form-property name="OldLines" type="com.total.total.forms.platts.PrixBean"/>
  4.  </form-bean>


 
Est ce que quelqu'un sait de quoi peut provenir cette erreur???

oui, ça vient du fait que la property "lines" est invalide.
