Hi Developers,

I try to customize the create content wizard as per the following url which is provided by alfresco.

Hi,

I can't explain this one, I have just tried the CustomWizard sample against the latest Community code and it works as advertised.

Could you possibly have some old classes hanging around in your environment? The exception is occurring when the wizard manager is trying to setup the custom wizard bean. This bean must implement the IWizardBean interface, which I'm presuming the one being picked up in your environment is not.
