<apex:pagemessages> not working in visualforce page.

<apex:pagemessages> not working in visualforce page.

Error with details directly redirected to new page
I want to show errormesage in standard error messagebox.
Below is the code details.

If the logedin user doesn't have FLS access then error message should get display on same page.
Visualforce Page:
  
<apex:pageMessages id="pmsg" />

<apex:pageBlock title="Cases">
   <apex:pageBlockButtons >
      <apex:commandButton value="Select "  onclick="return Test();" action="{!caseMethod}"  reRender="pmsg" />
   </apex:pageBlockButtons>

Controller Code: 
if (!CaseComment.sObjectType.getDescribe().isDeletable()){
          ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.FATAL,'Insufficient access'));
          return null;
        }
 delete ChildComment;

What is the use of onclick="return Test();"

Remove that part and try it.
OR
If there is a validation part or somthing in the Test() function, then use the following way.
  
<apex:page controller="testpagemsgcontroller">

<script>
function Test()
{
 alert('sss');
 if(true)
 {
     caseMethod();
 }
}


</script>
  <apex:pageMessages id="pmsg" />
<apex:form >
<apex:actionFunction name="caseMethod" action="{!caseMethod}" reRender="pmsg" />
<apex:pageBlock title="Cases">
   <apex:pageBlockButtons >
      <apex:commandButton value="Select " onclick="return Test();"  reRender="pmsg" />
   </apex:pageBlockButtons>
   
   </apex:pageBlock>
   </apex:form>
</apex:page>

If you get the answer, please mark it as the correct answer. It will be a help to others who are facing the same problem later.

Thank you Chamil for your reply.

I have tried using above code but unfortunately its not working.
My controller method (caseMehtod()) not getting called from javascript by using above code.

When i am putting reRender ="pmsg" in commandbutton its giving null value error in javascript code at (shid.value = store;) line but when i am removing that , page is reRendering but caseMethod() not getting called.

Below is the javascript code. 
function Test() {
        var radios = document.getElementsByName("parentId");
        var found = 1;
        for (var i = 0; i < radios.length; i++) {       
            if (radios[i].checked) {
               
                var store = radios[i].value;
                var shid = document.getElementById("j_id0:theForm:j_id5:hiddenId");
               
                shid.value = store; 
            
                found = 0;

                caseMethod();

                break;
            }
        }
        if(found == 1)
        {
            alert("Please Select the Case");
            return false;
        }
           
    }

Can you share the VF page and the controller?

Visual Force Page:

The visualforce page and controller seem to be OK. Can you debug your javascript, by giving alerts at different places in your script and check how far it is executing? or press F12 and check if it is reporting any javascript errors in the console?

The script may be throwing an error in getting or setting the value of an element.

Regards,
Krishna.
