Wrong type for attribute Expected found BigDecimal

Question

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}"

Controller:

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:

<apex:attribute
    name="invoice"
    description="Invoice Record"
    type="Invoice__c"
    required="true"/>
<apex:inputField value="{!invoice.Invoice_Amount__c}" />
<apex:inputField value="{!invoice.AnotherField__c}" />
