i have created an object with name PS_Detail__c .in this custom object i created a custom field of picklist type.in this picklist i defined two values Dollar ,Unit. when i go to P/S Detail Tab for creating a new PS_Detail__c object then i get None also as a value in picklist field .i want only Dollar and Unit as Picklist values .some one please help how to remove this None from Picklist

i am calling a batch class instance and after completing batch class i am calling two other batch class instance. finish() method code for first batch class is

 public void finish(Database.BatchableContext BC){ 

    List<Event__c> events =[SELECT Id from Event__c];

    delete events;
    System.debug('Executing finish');
      for(CalendarSettings__c c: [Select Id, Name, CalendarId__c,CalendarQuery__c,FieldToDisplay__c from CalendarSettings__c])
      {System.debug('Calendar Id is'+c.CalendarId__c);
           BatchPublicCampaignsToGoogle bjob = new BatchPublicCampaignsToGoogle(c.CalendarQuery__c,c.CalendarId__c,c.FieldToDisplay__c);
            Database.executeBatch(bjob,9);
        }

        }

the problem i am facing is i am expecting that Batch class BatchPublicCampaignsToGoogle will be called two times but it is called only one time and loop is running for two times (i analysed debug log ).why it is called only one time please some one explain??

i am sure i am doing a very small mistake.i created a visualforce page with code

 in this page in one select list i am showing Label of objects when user select label then in second list i show fields corresponding to that label but when i select a field actionFunction selectFieldApiName called.and in debug log it is showing pick list is true. but there is not picklist is rendering i think after selecting a picklist field ispickList getting true and then this pageblocksection item should render but it is not rendering can any one please tell where i am wrong.please help!!

 i created a visualforce page in which there is a code segment

<apex:column ><apex:commandButton value="{!if(item.i == size-1,'Add','Delete')}" action="{!if(size == 1,addElement(),removeElement())}"></apex:commandButton></apex:column>

i created a custom controller containing function

public PageReference addElement(){

return null;

}
public PageReference removeElement(){

return null;

}

but when i try to save the visualforce page it is giving me error

Error: Unknown function addElement. Check spelling  

can any one please tell me how to use if structure in action attribute so that it will properly work

i have create an apex class

public class sampleCon {
public PageReference setFieldApiName() {
System.debug('field are '+ Apexpages.currentPage().getParameters().get('fieldName'));
return null;
}
String[] countries = new String[]{};

public PageReference test() {
return null;
}

public List<SelectOption> getItems() {
List<SelectOption> options = new List<SelectOption>();
options.add(new SelectOption('US','US'));
options.add(new SelectOption('CANADA','Canada'));
options.add(new SelectOption('MEXICO','Mexico'));
return options;
}

public String[] getCountries() {
return countries;
}

public void setCountries(String[] countries) {
this.countries = countries;
}
}

and my visualforce page is 

<apex:page controller="sampleCon">
    <apex:form>
        <apex:selectList value="{!countries}"  multiselect="true" onchange="setFieldApiName({! countries})"> <apex:selectOptions value="{!items}"/> </apex:selectList><p/> </apex:form> <apex:outputPanel id="out"> <apex:actionstatus id="status" startText="testing..."> <apex:facet name="stop"> <apex:outputPanel> <p>You have selected:</p> <apex:dataList value="{!countries}" var="c">{!c}</apex:dataList> </apex:outputPanel> </apex:facet> </apex:actionstatus> </apex:outputPanel> <apex:form> <apex:actionRegion > <apex:actionFunction name="setFieldApiName" action="{!setFieldApiName}" reRender="out"> <apex:param value="" name="fieldName"/> </apex:actionFunction> </apex:actionRegion> </apex:form> </apex:page>

when i select an item from the list and actionFunction will be called and from which there is a call to apex class function setFieldApiName i am expecting that country which i selected in debug but getting "field are null" .how to get the country value when it is changed in list please some one explain

i am creating a visualforce page in this visualforce page there is a pageblocktable in each table row there are two selectlist one depends on other.first select list contains list of standard objects and other contain list of fields related to that object.there are several rows each contains these two lists.how to change content of second list related to first please give some guideline.firstly i created a wrapper class

public with sharing class AW_RuleCriteriaController2{
public String hello{get;set;}
public List<wrapper> wrap1{get;set;}
public AW_RuleCriteriaController2(ApexPages.StandardController controller){
wrap1 =new List<wrapper>();
wrap1.add(new wrapper());
wrap1.add(new wrapper());
}

public class wrapper{

public List<SelectOption> objOption{get;set;}
public List<SelectOption> fieldOption;
public List<SelectOption> matchType;
public String hello{get;set;}
public wrapper(){
objOption = new List<SelectOption>();
Map<String, Schema.SObjectType> mapObj = Schema.getGlobalDescribe();

Rule__c rule = [select object__c from Rule__c where id=:Apexpages.currentPage().getParameters().get('Id')];

String objType = rule.object__c;
Schema.SObjectType sobj;
if(objType !=null){
sobj = mapObj.get(objType);
Schema.DescribeSObjectResult objinfo = null;

objinfo = sobj.GetDescribe();
List<Schema.ChildRelationship> listChild = sobj.getDescribe().getChildRelationships();

for(Schema.ChildRelationship child: listChild){
Schema.DescribeSObjectResult descRes = child.getChildSObject().getDescribe();
system.debug(' PGB Children ' + descRes.getName());
system.debug(' PGB Children ' + descRes.getLabel());
objOption.add(new SelectOption(descRes.getName(),descRes.getLabel()));
}
objOption.add(new SelectOption(objInfo.getName(), objInfo.getLabel()));
}
}

}

}

after this i added objOption this contain the list of available objects .its giving the correct list in visualforce page

<apex:page standardController="Rule__c" extensions="AW_RuleCriteriaController2">

<apex:form >
<apex:pageBlock title="Filter Criteria" >
<apex:pageBlockSection >

<apex:inputtext value="{! hello}" />
</apex:pageBlockSection>

<apex:pageBlockTable value="{!wrap1}" var="item">

<apex:column >
<apex:selectList value="{! item.hello}" size="1">
<apex:selectOptions value="{! item.objOption}"></apex:selectOptions></apex:selectList></apex:column>

</apex:pageBlockTable>

</apex:pageBlock>

</apex:form>
</apex:page>

in my visualforce page i have some campaign object first user select an object then there is a multi picklist. in this picklist there is Label for all the fields user selects some fields then i have to show the value of these fields in the selected campaign object for showing multiple picklist my apex function is

 public List<SelectOption> getOptionalFields(){


   Map <String, Schema.SObjectField> fieldMap= Campaign.sObjectType.getDescribe().fields.getMap();
       List<SelectOption> fieldsName =new List<SelectOption>();

   for(Schema.SObjectField sfield : fieldMap.Values())
{
schema.describefieldresult dfield = sfield.getDescribe();
fieldsName.add(new SelectOption(dfield.getName(),dfield.getLabel()));

}

but i have no idea how to show value for the the field for exmple i have object instance like

Campaign c;

now i have to get value of any field whose Name is in string form.how to get corresponding value for that field.one solution is just write like say

String fieldName;

and use multiple if

if(fieldName=='Name')
c.Name=
if(fieldName=='Id')
c.Id=

is there any other convenient method??please explain!!

hi i have created a DataBase.Batchable class in which i am inserting a custom object named it Event__c

public class BatchCreateGCalendars implements Database.Batchable<SObject>, Database.Stateful, Database.AllowsCallouts {

 private List<Event__c> event_id;

}

i am creating say 1000 records of type events and then using the statement

insert event_id;

is this good or inserting each element one by one is more appropriate.

in my custom object i created only one  custom field of type text(255).so what is the maximum size of list can be(approximate)??

please guideline 

i write a visualforce page with source code

<apex:page controller="MyController1">

when i click on Advanced Search link nothing happens but i was expecting outputPanel with id "thePanel" should render.why it is not rendering please someone explain??

i have to create a ui for searching Opportunity . user fullfill the criteria and he will get the opportunity List accordingly  what i was thinking create a inputTextField when user enters any character then it will show result on keyup event .and one more section for Advance search in which there are various filter based on different Fields for Opportunity i am thinking of creating a PageBlock  and in that i will put select list or other visualforce component but the problem is by default pageblock is  in expand mode i want to show it in collapse mode initially when page renders so that user will click on the pageblock and then it expands how to accomplsih this and any other suggestion are welcomed please suggest ??

        pbButtons.childComponents.add(opPanel);  

        return pbButtons;

    }    
    at this line i am setting 
 pbButtons.location = 'both' ;

so it will render bottom and top but button is rendering only at top not at bottom and when i set this line to pbButtons.location='bottom' then there is no pageblock button in the page .can any one please tell why its not rendering at the bottom??

note=note1.get(0);
}

in line note1.size() i am getting Null pointer exception when i check for wheather note1.is null or not then its passing and showing that note1 is not null if i change this if statement to 

if(note1!=null){

if(note1.size() >0)

note=note1.get(0);}

if i omit conditional if statement then and call directly note1.get(0) then i am getting index out of bound exception expecting NullPointer excetion. can any one please explain weired behaviour of List class in testing when i run this url its work fine no null pointer exception i know size of list is zero but i am checking for negative case in testing there should be no null pointer exception i think please explain this behaviour of List class??
