The problem I'm facing is: whenever http://stackoverflow.com/questions/27019240/error-setting-expression-userbean-password-with-value I submit data whether is wrong or not (username and password) it ALLWAYS makes following field error appear: .Error setting expression 'userBean.password' with value ['XXX', ] .Error setting expression 'userBean.username' with value ['YYY', ] where 'XXX' is the password and 'YYY' is the username. My action class is: package direstruts.action; import static com.opensymphony.xwork2.Action.SUCCESS; import direstruts.model.UserBean; public class LoginAction extends GenericAction { @Override public void validate() { UserBean uB = getUserBean(); if(uB.getUsername().isEmpty()) { addFieldError("userBean.username", "Por favor Insira o Username de Utilizador"); } if(uB.getPassword().isEmpty()) { addFieldError("userBean.password", "Por favor Insira a Password de Utilizador"); } } public String getAuthentication() throws Exception { if(getUserBean().getAuthentication()) { addActionMessage("Log in bem Sucedido!"); return SUCCESS; } addActionError("Utilizador e/ou Password errados e/ou Utilizador já está logado"); return ERROR; } public String setNewUser() throws Exception { if(getUserBean().setNewUser()) { addActionMessage("User registado!"); return SUCCESS; } addActionError("Utilizador Já Existe! Tente Outro Username!"); return ERROR; } public String setQuitUser() throws Exception { if(getUserBean().setQuitUser()) { addActionMessage("Use
all parameters from {@link ActionContext#getParameters()} and sets them on the value stack bycalling ValueStack#setValue(String, Object), typically resulting in the values submitted in a formrequest being applied to an https://struts.apache.org/docs/parameters-interceptor.html action in the value stack. Note that the parameter map must contain a String key andoften containers a String[] for the value.The interceptor takes one parameter named 'ordered'. When set to 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 error setting 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 error setting expression the model class 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
