Bruce Phillips resolved WW-4168.
--------------------------------
Resolution: Fixed
Added if statement is isChecked method to verify that the Array of nameValues
is not null. Verified that all tests still pass and that code change fixes
issue by building and using the SNAPSHOT version of the JavaTemplates plugin
locally.

> 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.components.UIBean.mergeTemplate(UIBean.java:572)

> 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}
