> 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; }
>       }
