Hi Guys,

Hope we're all doing good!

I'm in the process of creating a Visualforce page with related child records arranged in a table but I'm not able to edit any of their fields or create new records. The parent object is called Bill of Lading while the child object is called Skids, it's like your opportunity to opportunity product/line item relationship wherein the Bill of Lading has child skid records. I will be posting both screenshot links of the page along with code snippets that may aid in my query on creating, editing child records on a Visualforce page, many thanks!

Non-working Visualforce code:

<apex:pageBlock >
<apex:pageblockTable title="Bill_of_Lading__c" value="{!Bill_of_Lading__c.Skids__r}" var="BOL">
<apex:dataTable value="{!Bill_of_Lading__c.Skids__r}"
                      var="BL"
                      cellPadding="4" border="1">    
       <apex:column headervalue="{!BOL.Dimension__c}">
       {!BOL.Dimension__c}
       </apex:column>
       <apex:column value="{!BL.Number_of_Pieces__c}">
       </apex:column>
       <apex:column >
            {!BL.UOM__c}
         </apex:column>
       </apex:dataTable>
 </apex:pageblockTable>
</apex:pageBlock>

</apex:form>

<apex:detail relatedList="false"/>
  <apex:relatedList list="Skid__c"/>

</apex:page>

 Draft extension:

    public List<Skid__c> getSkids()
    {
       if ( (null!=getBillofLading().id) && (skids == null) )
       {
           skids=[SELECT Id, Name, Bill_of_Lading__c, Dimension__c, Number_of_Pieces__c, UOM__c, Weight__c
                         FROM Skid__c
                         WHERE Id =: getBillofLading().id
                         ORDER BY CreatedDate];
       }                           
       return skids;
    }
