When following the steps on this page to make an example VF page with the Ideas Controller https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_pages_ideastandardcontroller.htm

I get the following error

Unknown constructor 'MyIdeaExtension.MyIdeaExtension(ApexPages.StandardController controller)'

Does anyone know how to fix this? My controller looks exactly like the example, as does my VF page... with "standardController="Idea" extensions="MyIdeaExtension"" in the apex:page. Any help would be appreciated!

Edit: Found part of the issue, although it leads to another error

In the docs for the extension it has

public MyIdeaExtension(ApexPages.IdeaStandardController controller) { ideaController = (ApexPages.IdeaStandardController)controller; }

when it should be using the ApexPages.StandardController for the argument in the constructor.

public MyIdeaExtension(ApexPages.StandardController controller) { ideaController = (ApexPages.IdeaStandardController)controller; }

But then this gives me an error on the actual VF page saying

Invalid conversion from runtime type ApexPages.StandardController to ApexPages.IdeaStandardController

If someone can successfully implement the example in the docs I linked, I would love to know.

    Did you save the class with the filename MyIdeaExtension? You should.

  • @DougB Yes, the name is the same MyIdeaExtension.cls

    Can you post your whole extension and page please?

  • @BrianMansfield it was the exact same as the docs like I said in the post, and I just found the issue which I answer.

  • @BrianMansfield nevermind, that fix creates another issue which I've mentioned in my post, this is very frustrating.

"The IdeaStandardSetController and IdeaStandardController classes are currently available through a limited release program. For information on enabling these classes for your organization, contact your Salesforce representative."

Have you checked with Salesforce that it is enabled in your Org?

  • I will look into this thanks. May be the issue. Do you know how I would check if its enabled myself?

    I'm going to delete my answer because after a quick search, this seems like it's definitely the explanation. Nice catch!

  • @MikeNorthorp I suspect that the fact that your code is giving those errors suggests that it isn't enabled but I don't know any way to check without contacting SF. Good luck!

    @BrianMansfield your answer made a lot of sense too, I hadn't heard of these new controllers before today. Every day is a school day! :-)

  • It wasn't enabled in the Org, had to contact Salesforce to get it enabled, thanks all!
