Struts2 validations not working properly

I'm new to struts2. I'm doing form validation using xml. But few of my feilds are getting invalidated everytime.

The filds which are getting invalidated are: police station, father's name, phone number and id number.

My validation for phone number is showing two error messages. One that i have provided in my xml and other is Invalid field value for field "phone".

Further, for client side validation, if i add validate=true" to my <s:form> tag, following error appears just after my form in jsp

FreeMarker template error!


Method public java.util.List org.apache.struts2.components.Form.getValidators(java.lang.String) threw an exception when invoked on org.apache.struts2.components.Form@17bb1c6
The problematic instruction:
----------
==> list tag.getValidators("${tagName}") as aValidator [on line 66, column 9 in template/~~~xhtml/form-close-validate.ftl]
 in include "/${parameters.templateDir}/${parameters.expandTheme}/form-close-validate.ftl" [on line 25, column 1 in template/xhtml/form-close.ftl]
----------

Java backtrace for programmers:

Please help me resolving these problems. I'm using Struts 2.3.16 libraries.

Update Validations are NOT working when i leave some feilds blank. Exception part is still unresolved when validate="true" is ON in the struts form tag. Here's the updated code.

** Updated jsp form**

<s:form name="register-complaint" action="registerComplaint validate=""true" method="post">
    <s:textfield name="policeStation" label="Nearest Police Station"/>
    <s:select name="district" label="District"

I got same issue in my project, then I got one solution on this Link https://coderanch.com/t/555477/framework/FreeMarker-template-error

Just change your action in the jsp page like

s:form action="loginprocess.action" validate="true"

I hope this will help you.

phone number is showing two error messages because you might have taken phone number as a int or long in your action.

If we don't provide anything(not even 0) in a text field whose data type is int or long in your action, then from JSP form it by default pass an empty string to your action.

So simply inside your action setPhone() method could not set a string(i.e empty string) to the int or long field & it show action

error i.e Invalid field value for field "phone".

If you have taken phone as int or long you should use intRangeValidator or long validator instead of required validator.

freemarker.template.TemplateModelException - This exception usually comes when you are trying to display a values from a list but that list you are not passing from action class or if you do not have getters & setters for given list.

Hope this will help you.

Please show you action class for further help.
