Extension/Constructor on a Component

Question

I have a Component inside of a Visualforce Page. I am not sure if this line of connection is causing a break but my issue is with my constructor. It is not taking in the params I am passing:

Page:

<apex:page standardStylesheets="false" standardController="Credit_Review__c" action="{!checkValidVersion}" extensions="CreditreViewScreenController,CreditReportRemoting,sendToWebService2,RecommendationPanelController" sidebar="false" showHeader="false">
    <c:CreditReviewScreenRelatedDealsTab creditReviewObj="{!creditReview}" table="{!TableValue}" associatedContactsObjMap="{!ConsumerCreditSummaryMap}" associatedContactsObj="{!associatedContactList}" CreditSummaryObj1="{!CreditSummaryObj1}"/>

Component:

<apex:component id="CreditReviewScreenRelatedDealsTab" controller="IDAnalyticsController" extensions="oliviaTestClass" allowDML="true">

Extension:

public class oliviaTestClass {

    public oliviaTestClass(ApexPages.StandardController controller){}
}

I have tried passing in a StandardSetContoller, extending oliviaTestClass with extends IDAnalyticsController, assigning variable controller a value.... but I continue to get error: Error:(1, 1) Unknown constructor 'oliviaTestClass.oliviaTestClass(IDAnalyticsController controller)' What am I missing with constructors and class extensions? I have followed the documentation below with no success.

*note: I did not include IDAnalyticsController for it is over 1000 lines long

Answer 1

Although the constructor argument is often an ApexPages.StandardController because an SObject type is specified in the controller argument, where you specify a specific class as the controller argument it is that class name that needs to be the argument to the extension class constructor:

public class oliviaTestClass {
    private IDAnalyticsController ac;
    public oliviaTestClass(IDAnalyticsController ac) {
        this.ac = ac;
    }
    ...
}
