Neither BindingResult nor plain target object for bean name 'cmd' available as request attribute

[Parth Patel]

I am new to Spring and I am not able to solve this issue. I read almost all the post regarding this issue but I am not able to figure out the problem in my code.

java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'cmd' available as request attribute

I am getting this error only at the loading of the page for the first time. In edit mode it works perfectly fine.

Controller Class Object

    @Override
    protected final Object formBackingObject (final HttpServletRequest request) throws Exception {
       
        CmdMasterModule cmd = new CmdMasterModule (id);

        return cmd;
    }

JSP
<form id="detail" name="detail" method="post" enctype="multipart/form-data" action="detail.do?id=${cmd.masterId}"> <div class="buttonNewRelative" style="padding: 10px"> <c:if test="${!read_only}"> <spring:bind path="cmd.saveButton"> --------------------------------------------I am getting the error on this line <input type="hidden" name="${status.expression}" id="${status.expression}" /> </spring:bind> </c:if> </div> </form>
Bean
<bean name="/detail.do" class="com.controllers.UpdateController"> <property name="successView"> <value>redirect:/detail.do?id=</value> </property> <property name="sessionForm"> <value>false</value> </property> <property name="commandName"> <value>cmd</value> </property> <property name="commandClass"> <value>com.commands.CmdMasterModule</value> </property> <property name="customValidator"> <ref bean="masterModuleValidator" /> </property> <property name="formView"> <value>mm_Detail</value> </property> </bean>
Object

public class CmdMasterModule implements Serializable {
    private long  masterID    = 0;
    private String saveButton;

    public CmdMasterModule (final Long Id) {
        masterID= Id;
    }

    public String getSaveButton () {
        return saveButton;
    }

    public void setSaveButton (final String newSaveButton) {
        saveButton = newSaveButton;
    }
}

Any help will be appreciated.

Thanks,

<property name="commandClass"> <value>com.commands.CmdMasterModule</value> //I don't see your class CmdMasterModule declare any package name like this. </property> //This doesn't seem right, it doesn't bind to any class, I think the problem is here and relate to above. <property name="commandName"> <value>cmd</value> </property>


In summary, you need to define the commandClass CmdMasterModule and bind it with command name "cmd". Your bean configuration is not correct so, it won't work. Reconfigure and see if that help...

Tommy Delson,

The command class is already defined. I didn't understood what exactly you mean to say. The same structure is applied everywhere in the project and everything else runs perfect. I am not able to understand why only this module fails to load for the first time.

Did you mean to say that I need to set the command class and command name in the constructor of the controller ?

for e.g :

public class UpdateController extends SimpleFormController {

    
    public UpdateController() {
    	setCommandName("cmd");
        setCommandClass(CmdMasterModule.class);
    }

    @Override  
    protected final Object formBackingObject (final HttpServletRequest request) throws Exception {  
         
        CmdMasterModule cmd = new CmdMasterModule (id);  
  
        return cmd;  
    } 

I tried it with the above code too but it didn't help.

import com.commands;

public class CmdMasterModule implements Serializable {  
    private long  masterID    = 0;  
    private String saveButton;  
  
    public CmdMasterModule (final Long Id) {  
        masterID= Id;  
    }  
  
    public String getSaveButton () {  
        return saveButton;  
    }  
  
    public void setSaveButton (final String newSaveButton) {  
        saveButton = newSaveButton;  
    }  
} 

Please can you give me an example related to my code or explain a little more detail about the code ?

Thanks,
Parth

Can once try with form binding?
Can you show us your complete code, because i can't see id used in controller, declared anywhere and also JSP, so that we can see the taglib used for <spring:bind>.

P:S: Still having controllers extend the spring classes, its been deprecated from spring 3.0 and will be removed in the future, I would recommend to use annotations instead of SimpleFormControllers.
