Spring binding

I would change
<c:out  value="${commandMap.model["config"].supportDistribution}"/>
to
<c:out  value="${commandMap.model['config'].supportDistribution}"/>

For this error pblm is
The checked attribute is without a value. You'll have to set it to something or remove it.

For eg:
you have radio button means that u set as default but u didnt mention the value for the  radio button..

check whether u have given default value for any input ??

Below is the HashMapCommand bean
import java.util.HashMap;
public class HashMapCommand {
      private HashMap<String, Object> model = new HashMap<String, Object>();

      /**
       * @return the model
       */
      public HashMap<String, Object> getModel() {
            return model;
      }

      /**
       * @param model the model to set
       */
      public void setModel(HashMap<String, Object> model) {
            this.model = model;
      }
}

and my controller formbackingobject is,

   protected Object formBackingObject(HttpServletRequest request) throws ServletException {
          
          HashMapCommand command = new HashMapCommand();
        command.getModel().put("userName", Session.getUserManager().getCurrentUser().getPerson());
        command.getModel().put("userRole", Session.getUserManager().getCurrentUser().convertRolesToString());
      
          Configuration config;
            String configName = request.getParameter("configName");
            ConfigurationDAO configDAO = new ConfigurationDAOImpl();
            configDAO.setDataSource(Session.getDataSource());
            config = configDAO.getByName(configName);
            command.getModel().put("config", config);
        return command;
    }
}    

I also tried,

<c:out  value="${commandMap.model['config'].supportDistribution}"/>
even then i get the same exception.

Please help

is ${commandMap.model["config"].supportDistribution} having  value i think tht dont have value ...
do one think can u remove that
       <input type="text" id="distList" disabled name="distList" > and run

or print that value ...

The default value means, when the jsp is shown first it will fill the value from the commandMap, so that is why i used value=c:out tag.

ya that making the pblm check this 3 solution i think ...

ur     <c:out  value="${commandMap.model["config"].supportDistribution}"/> dont have value ....

this is ur error !!

after check that u reply or if u got the solution ..
press the accept button(which solution is correct) and  close the  question..

I took the value property and now it is throwing this exception

org.apache.jasper.JasperException: /WEB-INF/jsp/modifyConfigManagement.jsp(38,4) "${commandMap.model.['userConfig']}" contains invalid expression(s): javax.el.ELException: Error Parsing: ${commandMap.model.['userConfig']}

I debugged and in the controller, before sending the hashmap, i am able to see the values for userConfig

and line 38 of the jsp is,
<c:set var="userConfig" value="${commandMap.model.['userConfig']}"></c:set>

what u chnaged??
can u tell me??

normaly
system.out.println("============="+${commandMap.model["config"].supportDistribution}") ;
in ur jsp...

<input type="text" id="distList" disabled name="distList" value="<c:out  value="${commandMap.model["config"].supportDistribution}"/>">      
replace this
 <input type="text" id="distList" disabled name="distList">

      

oh my goodness i got the answer. You are the best.

Thank you very much
