I'm not sure why it's failing on this particular field and I have couple of other fields with same inputField, what I'm doing wrong here?

Wrong type for attribute <c:invoicedetail InvoiceAmount="{!myinvoice.Invoice_Amount__c}">. Expected Invoice__c, found BigDecimal (Line: 1, Column: -1)

Here is my very simple VF component:

<apex:attribute name="InvoiceAmount" description="Invoice Amount" type="invoice__c" required="true"/>
<many other inputfields here....
<apex:inputField id="in" value="{!InvoiceAmount.Invoice_Amount__c}"/>

VF page:

<c:mycomponent  InvoiceAmount="{!myinvoice.Invoice_Amount__c}"


public with sharing class InvoiceController {
    public InvoiceController() {
       Invoice__c myinvoice = [/*SOQL*/];

You need to pass the record instead of its field. Since you seem to reference other fields on the record, this is the route you should take to fix your issue. I would rename your attribute to invoice or invoiceRecord instead.

<c:mycomponent invoice="{!myInvoice}" />

Then your component would be:

    description="Invoice Record"
<apex:inputField value="{!invoice.Invoice_Amount__c}" />
<apex:inputField value="{!invoice.AnotherField__c}" />
  • what is the best practice in this situation?

  • if i try to change to type="Decimal" in the VF component then I'm getting this error <apex:inputField> can only be used with SObjects, or objects that are Visualforce field component resolvable

  • I do not think so, I have posted VF page, VF Comp, and Controller, why do you think I'm giving incomplete picture

  • @AbuHamzah You must use type="Invoice__c" because you have many inputField tags.

  • I have exactly how you have laid-out and when I have this in my VF page <c:mycomponent invoice="{!myInvoice}" /> then getting this error unknown property create apex property invoice.invoice__c error
