Hi Folks,
My recordsetVar is not displaying records even the object is having records in my Org.
Please find the peiece of code below and corresponding UI

<apex:page standardController="Account" recordSetVar="records" >
<apex:form >
<apex:pageBlock >
<apex:pageBlockTable value="{!records}" var="r">
    <apex:column headerValue="Name" value="{!r.Name}"/>
    <apex:column headerValue="Phone" value="{!r.Phone}"/>
</apex:pageBlockTable>
</apex:pageBlock>
</apex:form> </apex:page>


Regards
Rama
 

Hi friends !
I have below snippet code which actually prevent duplicate contacts for an Account..but it's preventing every record to be insert...
trigger dupconprevention on Contact (Before Insert,Before Update) {
Map<String,Contact> lstb2 = new Map<String,Contact>();
for(Contact c:trigger.new){
if(lstb2.containskey(c.LastName) && lstb2.get(c.LastName).AccountId == c.AccountId){
contact cc = lstb2.get(c.LastName);
c.LastName.addError('Another contact with same Name exist');
}else
lstb2.put(c.LastName,c);
system.debug('my map'+lstb2);
}

for(Contact c:[select Id,AccountId,LastName from Contact where LastName In:lstb2.keyset()]){
Contact c2 = lstb2.get(c.LastName);
system.debug('Contact to be insert'+c2);
if((c.AccountId == c2.AccountId) && (c.LastName == c2.LastName)){
c2.LastName.addError('Already Exist');
}
}
} 

Hai Friends !

      lee.setPageNumber(1);
