Folks,

If you try using the isempty() function similar to the list and set methods  for strings then it will throw an error.

Instead use the below syntax

String st = 'Hello'; 
Boolean val= String.isEmpty(st);

Thanks,

Displaying Calendar on Visualforce page

I have a VF page with a save button. i also have a apex:message in a outputpanel

<apex:pageBlockButtons id="blockbuttons">
          <apex:commandButton value="Save"  onclick="performValidation()" id="saveid"/>
          <apex:commandButton value="Cancel" action="{!ok}" />
                   
      </apex:pageBlockButtons>

 <apex:outputpanel id="mess">
 <apex:pageMessages />
 </apex:outputpanel>
 
  <apex:actionFunction name="save" action="{!Save}" rerender="mess"/>

<script  language="javascript" type="text/javascript">
        function performValidation()
        {
        Do something
        save();
        }

 In my controller i am validating some values and throwing an apex messages

           ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.ERROR,'Error'));

 This message doesnt seem to be getting displayed. The whole page gets refreshed after the save method is called and probably the messages are displayed. Is there anything that can be done to refresh only the output panel and not the whole page.

Hi All,

I need to use controller class variable in javascript onClick event. For this I used below code.

I am getting NULL value instead of  "samplevariable" which hardcoded in class variable while click Javascript function and m

VFP:

<apex:page id="pageForm" controller="formController">
    <apex:form id="form">
         <apex:inputHidden value="{!myObject.textdata}" id="hidBusiness"/>
        <apex:commandButton id="btnSave" onclick="javascript&colon;if(!confirmation()) return false;" value="save"/>
    <script>
       function confirmation()
        {
          var hidBusiness= document.getElementById("{!$Component.hidBusiness}");
          alert('Hi'+hidBusiness);
        }
    </script>
    </apex:form>
</apex:page>

Controller class:

public class formController {

  public class MyObject {
     public String textdata = 'samplevariable';

    public String getTextData() { return textdata; }
    public void setTextData(String data) { textdata = data; }

  }

I'm building a form in VisualForce, and I can't get the elements of a pageBlockSection to line up. Here's my problem: the dropdown label is not in bold, it is not aligned horizontally with the dropdown, and neither label nor dropdown is aligned with the inputFields below it.

How can I get these to align? It seems I would have to group the label and dropdown somehow.

Here's my visualforce code:

<apex:pageBlockSection title="Account Information" columns="1">

<apex:outputLabel value="Record Type" for="AccountRT"/>
<apex:selectList id="AccountRT" value="{!theAccountRecordTypeID}">
<apex:selectOptions value="{!theAccountRecordTypeOptions}"/>
</apex:selectList>

<apex:inputField value="{!theAccount.name}"/>

</apex:pageBlockSection>

To auto populate the standard employee number field on user object I have created auto no field and using a trigger on object user on after insert I am updating also . Also as per my requirement I have to also create a contact record on the after insert of user . But is not allowing me to do both the dml operation together.

the code is as follows:

trigger employeenoautopopulate on User (after insert)
{
 
     List<Contact> Con = new List<Contact>();
 
     for(User usr: Trigger.new)
     {
             System.debug('****** condition true');
             Contact con_temp = new Contact();
             con_temp.FirstName = usr.FirstName;
             con_temp.LastName = usr.LastName;
             con_temp.Date_Of_Joining__c = usr.Date_of_Joining__c;
             con_temp.User__c = usr.Id;
             con_temp.OwnerId = usr.Id;
             con_temp.Employee_Number__c = usr.Employee_Number__c;
             Con.add(con_temp);
      }  
      if(Con.size()>0)
      {
       insert Con;
        System.debug('****** insert done');
      }
   
     Set<Id> userid = new Set<Id>();
     for(User usr: Trigger.new)
     {
  
         userid.add(usr.Id);   
     }
  
     User[] usr = [select Id, EmployeeNumber,Employee_Number__c from user where Id in :userid];
     for(Integer i=0;i<usr.size();i++)
     {
        usr[i].EmployeeNumber = usr[i].Employee_Number__c ;
        System.debug('****'+usr[i].Employee_Number__c);
     }
      
      update usr;
      System.debug('****** update done');
}

I am getting following exception:

  String userId = UserInfo.getUserId();
  String firstName = UserInfo.getFirstName();
  String lastName = UserInfo.getLastName();

I know i can do {!$User.Email} but that would only be in the visualforce pages.
How do I get the email address of the logged in user in controller.
