not a valid child relationship name for entity

Hello,

Been working on this too long and need some help.  I have a Master Detail relationship between Opportunity and a custom object.  I have added the Related list as I have added others to the VF Page but it is giving me the above error.  The code is very simple but I must be missing something.

Any help would be great.

Thanks Dwayne

 

<apex:outputPanel rendered="{!hasPolicy}" id="UpsellCampaignOppt">
	    <table style="width: 1100px;">
	    	<tr>
	    	<td colspan="1">
				<apex:pageBlock tabStyle="Campaign">
	    			<apex:pageBlockSection id="UpsellCO" title="Upsell Campaign Opportunities" collapsible="true" columns="1">
	    				<apex:relatedList list="Upsell_Campaign_Opportunities__r" subject="{!policy.Id}"/>
	   				</apex:pageBlockSection>
	   				<script>twistSection(document.getElementById("{!$Component.UpsellCO}").childNodes[0].childNodes[0]); </script>
	 			</apex:pageBlock>
			</td>
	 		</tr>
		</table>
	</apex:outputPanel>

Do one thing go to your child object.
Locate the Lookup to opportunity field.
Click the Field name to open the detail.
There should be a field called "Child Relationship Name", we generally add "__r" to this name to render the related list/ or to do a parent to child query

I can see you are using a variable called policy.
Is this is instance of Opportunity ?
Jack InsJack Ins

Yes.  VF page is controlled by apex class the apex class is build based on Opportunity

public class PolicyDashboardController {

    public Opportunity policy{get;set;}

 I have other related lists that work with no problems are set up the same as this object.  The only difference is that this object halso has a master detail relationship to Campaigns too.

 

Here is code of my other related list:

<apex:outputPanel rendered="{!hasPolicy}" id="UndVerAlerts">
	    <table style="width: 1100px;">
	    	<tr>
	    	<td colspan="1">
				<apex:pageBlock >
	    			<apex:pageBlockSection id="UndwrVer" title="Underwriter Verifications/Alerts" collapsible="true" columns="1">
	    				<apex:relatedList title="" list="Underwriter_Verifications__r" subject="{!policy.id}" pageSize="5"/>
	   				</apex:pageBlockSection>
	   				<script>twistSection(document.getElementById("{!$Component.UndwrVer}").childNodes[0].childNodes[0]); </script>
	 			</apex:pageBlock>
			</td>
	 		</tr>
		</table>
	</apex:outputPanel>

WOW Not thats interesting.  It worked for this. Why would it work for my other related object but differently for this one?

Check the Child Relationship name shomehow they matched.
