Subject [jira] Updated: (WW-3120) <s: checkbox> returns boolean type to ParameterAware
Date Thu, 07 May 2009 16:26:30 GMT

     [ https://issues.apache.org/struts/browse/WW-3120?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jeff Kelley updated WW-3120:
----------------------------

    Description: 
My action class is implementing ParameterAware so I can get all the name/value pairs on the
page. When using the <s:checkbox> tag the value is a boolean in the ParameterMap, not
a String[].

JSP:
<s:checkbox name="MCN"  fieldValue="true" theme="simple"/>

Action Class:
public class Upload extends ActionSupport implements SessionAware, ParameterAware
{
     private Map<String, String[]> parameterMap;

     public String execute()
     {
        String[] stuff;

        stuff = parameterMap.get("MCN");

        return SUCCESS;
     }

     public void setParameters(Map paramMap)
    {
        parameterMap = paramMap;
    }
}

When the execute() method runs I get a class cast exception on 'stuff' since it cannot cast
from a boolean to a String[].

When I debug the remote JVM with Eclipse 3.4 I get the following in the parameterMap : {password=[Ljava.lang.String;@1e6ee98,
struts.token.name=[Ljava.lang.String;@3a3e21, MCN=false, struts.token=[Ljava.lang.String;@9ac272,
uID=[Ljava.lang.String;@1c519e2}.
