Note that the parameter map must contain a parameters interceptor example struts2 String key andoften containers a String[] for the value.The interceptor takes one parameter named 'ordered'.

true action properties are guaranteed to beset top-down which means that top action's properties are set first. Then it's subcomponents properties are set.The reason for this order is to

enable a 'factory' pattern. For example, let's assume that one has an actionthat contains a property named modelClassthat allows to choose what is the underlying implementation of model.By assuring that modelClassproperty is set before any model properties are set, it's possible to choose modelimplementation during action.setModelClass()call. Similarly it's possible to use action.setPrimaryKey()property set call to actually load the model class interceptor-ref name= params from persistent storage. Without any assumption on parameterorder you have to use patterns like Preparable Interface.Because parameter names are effectively OGNL statements, it is important that security be taken in to account.This interceptor will not apply any values in the parameters map if the expression contains an assignment (=),multiple expressions (,), or references any objects in the context (#). This is all done in the #acceptableName(String)method. In addition to this method, if the action being invoked implements theParameterNameAwareinterface, the action will be consulted to determine if the parameter should be set.In addition to these restrictions, a flag ( ReflectionContextState#DENY_METHOD_EXECUTION) is set such thatno methods are allowed to be invoked. That means that any expression such as person.doSomething()orperson.getName()will be explicitly forbidden. This is needed to make sure that your application is notexposed to attacks by malicious users.While this interceptor is being invoked, a flag ( ReflectionContextState#CREATE_NULL_OBJECTS) is turnedon to ensure that any null reference is automatically created - if possible. See the type conversion documentationand the InstantiatingNullHandlerjavadocs for more information.Finally, a third flag ( XWorkConverter#REPORT_CONVERSION_ERRORS) is set that in

Thanks, Nishan Patel SCJP 1.5, SCWCD 1.5, OCPJWSD Java Developer,My Blog David Newton Author Rancher Posts: 12617 I like... posted 7 years ago Sounds like there are form parameters that don't have corresponding setters in the action. Without any code it's impossible to help much more. Also note that in earlier S2 versions these messages were logged at ERROR level; IIRC it's been changed to DEBUG (I think) in later versions. I don't recall which version saw that change committed. Nishan Patel Ranch Hand Posts: 689 I like... posted 7 years ago Thank you for Reply
