Manasa.R Error Message Not getting displayed on VF Page
Hi,
I need to display an error message when one of the fields is null.
VF Page :
<apex:page controller="conAddmailsIds" sidebar="true" showHeader="true" >
<apex:pagemessages/>
<apex:pageBlock id="block">
<apex:pageBlockSection >
<apex:panelGroup >
<center>
<apex:selectList id="select" value="{!selectId}" size="1">
<apex:selectOptions value="{!autoRun}" />
</apex:selectList>
<apex:inputText id="searchText" value="{!searchText}"/>
<apex:commandButton value="Search" action="{!getAllEmployees}" rerender="searchResult" status="status"/>
</center>
<apex:commandButton value="Hierarchy" action="{!getEmpHierarchyData}" rerender="searchResult" status="status"/>
</apex:panelGroup>
</apex:pageBlockSection>
<apex:messages/>
<apex:actionStatus id="status" startText="Searching... please wait..."/>
--------
</apex:page>
Controller:
public PageReference getAllEmployees(){
if(searchText == '' || searchText == null){
ApexPages.Message myMsg = new ApexPages.Message(ApexPages.Severity.ERROR, 'Add your message here');
ApexPages.addMessage(myMsg);
return null;
}
......
I have tried with both apex:messages and apex:pagemessages, still nothing is working. Is there any page level settings to be done?
I am not able to figure out why the error message is not getting printed. Is there anything else i need to do here?
Thanks in advance!

You are only rendering 'searchResult' how ever either you render the entire page or atleast the message. Modify your code as below.
Put your message tag inside <apex:pageblock> and add <apex:form>
<apex:page controller="conAddmailsIds" sidebar="true" showHeader="true" >
<apex:form>
<apex:pageBlock id="block">
<apex:pageMessages id='msg'/>
<apex:pageBlockSection >
<apex:panelGroup >
..........
.......in your command button render the messages as well
<apex:commandButton value="Search" action="{!getAllEmployees}" rerender="searchResult,msg" status="status"/>
//close the </apex:form> in the end.
Remove <apex:messages/> You don't need it.
In your controller it looks fine but try to change the add message to
ApexPages.AddMessage(new ApexPages.Message(ApexPages.Severity.ERROR,'System Error, 'Your error message '));
