By

// Override default size 20 to 2 as below.
If you want to overide the record per page then you will have to use custom controller for Sales__c object as below. In the below custom controller, i have set page size =2 so that you can see the effects of pagination.

----------------VF------------------------------------
<apex:page controller="CustomObjectPaginationController">
     <apex:form >
        <apex:pageBlock >
           <apex:pageMessages />
         
            <apex:pageBlockButtons >
               <apex:commandButton value="Save" action="{!setCon.save}"/>
               <apex:commandButton value="Return" action="{!setCon.cancel}"/>
            </apex:pageBlockButtons>
         
            <apex:pageBlockTable value="{!customObjects}" var="s" id="table" rows="10">
                <apex:column headerValue="Account Name">
                  <apex:outputField value="{!s.Name}"/>
                   </apex:column>
            </apex:pageBlockTable>
         
           <apex:commandLink action="{!setCon.previous}" value="Previous Page" rendered="{!setCon.hasPrevious}"/>&nbsp;
           <apex:commandLink action="{!setCon.next}" value="Next Page" rendered="{!setCon.hasNext}"/>&nbsp;
           <apex:commandLink action="{!setCon.last}" value="Last Page" rendered="{!setCon.hasNext}"/>&nbsp;
           <apex:commandLink action="{!setCon.first}" value="First Page" rendered="{!setCon.hasPrevious}"/>
         
         </apex:pageBlock>
      </apex:form>
 </apex:page>
---------------------------------

Controller
----------------------------------
public class CustomObjectPaginationController{
public Integer size{get;set;}
    public CustomObjectPaginationController(){
        size=2;
    }
   
    public ApexPages.StandardSetController setCon {
        get {
            if(setCon == null) {              
                setCon = new ApexPages.StandardSetController(Database.getQueryLocator(
                      [select id,Name from sale__c]));
                setCon.setPageSize(size);
            }          
            return setCon;
        }
        set;
    }
   
    // Initialize setCon and return a list of record  
    public List<sale__c> getCustomObjects() {
         return (List<sale__c>) setCon.getRecords();
    }
}

Error : "Trigger must be associated with a job detail"

By
Error : "Trigger must be associated with a job detail" Hi All, I was just trying to schedule my schedulable class ' Schedular_GlobalAppLogPurgeBatch ' in Apex. That time I was facing this error. Error : "Trigger must be associated with a job detail" e.g. Schedular_GlobalAppLogPurgeBatch globalPurgeBatchSchedular = new Schedular_GlobalAppLogPurgeBatch(); System.schedule(' Global App Logs Purge ', '0 0 * * * ? *', globalPurgeBatchSchedular); you can notice there is a space after " Global App Logs Purge ", when I removed this extra space from the name (" Global App Logs Purge ") my class was scheduled as expected. Corrected Space from code: Schedular_GlobalAppLogPurgeBatch globalPurgeBatchSchedular = new Schedular_GlobalAppLogPurgeBatch(); System.schedule(' Global App Logs Purge ', '0 0 * * * ? *', globalPurgeBatchSchedular); I hope this will help you.
