Description

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:

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;
}

Cheers Greg
