------------------------------

             Summary: npe on Checkboxlist 
                 Key: WW-4168
                 URL: https://issues.apache.org/jira/browse/WW-4168
             Project: Struts 2
          Issue Type: Bug
          Components: Plugin - Java Templates
    Affects Versions: 2.3.15.1
         Environment: tomcat/centos 5
            Reporter: Greg Huber
            Priority: Minor


Hello,

I am getting null pointer exceptions on line :

Caused by: java.lang.NullPointerException
at template.events.CheckboxListHandler.isChecked(CheckboxListHandler.java:125)
at template.events.CheckboxListHandler.generate(CheckboxListHandler.java:80)
at org.apache.struts2.views.java.DefaultTheme.renderTag(DefaultTheme.java:120)
at org.apache.struts2.views.java.JavaTemplateEngine.renderTemplate(JavaTemplateEngine.java:95)
at org.apache.struts2.components.UIBean.mergeTemplate(UIBean.java:572)
at org.apache.struts2.components.UIBean.end(UIBean.java:526)

we need to check for if(nameValues)!=null

ie:

{code:java}
private Boolean isChecked(Map<String, Object> params, String itemKeyStr) {
Boolean checked = false;
if (itemKeyStr != null) {
String[] nameValues = (String[]) params.get("nameValue");
if(nameValues)!=null  // need this <<<<<<<<<<
for (String value : nameValues) {
if (checked = value.equalsIgnoreCase(itemKeyStr))
{ break; }

}
}
}
return checked;
}

{code}

Cheers Greg
